Kee, Dohyung. "Characteristics of Work-Related Musculoskeletal Disorders in Korea." International Journal of Environmental Research and Public Health 20, no. 2 (2023): 1024. http://dx.doi.org/10.3390/ijerph20021024.
Full textAbstract:
This study aimed to analyze trends for work-related musculoskeletal disorders (WMSDs) from 1996 to 2020 in Korea and to investigate characteristics of WMSDs, including WMSD approval rates, distribution by WMSD names, and the effects of industry type and size, and workers’ age and gender on WMSD occurrence. The data included those obtained from the official yearbooks for industrial accidents published by the Ministry of Employment and Labor and those obtained personally from the Korea Workers’ Compensation & Welfare Service. The results showed that although the incidence of WMSDs differed by year, approximately 9500 cases of WMSDs occurred in 2019 and 2020, the incidence rate of WMSDs was approximately 5.0 per 10,000 workers, and the proportions of WMSDs among industrial accidents were almost 9%. Low back pain was the leading cause of WMSDs; WMSDs occupied 9.5–71.5% of total occupational diseases by year and occurred most frequently in the manufacturing industry, followed by construction, transportation/warehouse and communication, and mining industries, and nearly 60% of WMSDs occurred in small business with <50 workers. Among chronic WMSDs, rotator cuff syndrome in the shoulder ranked first, intervertebral disc disorders second, and rotator cuff and tendon injuries third. By body parts, the shoulder was most susceptible to chronic WMSDs, followed by the low back, leg, and elbow/lower arm. The chi-square test and logistic regression analysis showed that industry type and size and workers’ gender and age were significantly associated with WMSD approval. It can be concluded that the WMSD preventive efforts should focus on low back pain and rotator cuff syndrome by WMSD name, manufacturing by industry, small business by industry size, men by gender, and aged workers by age.

Full textAbstract:
Purpose The purpose of this paper is to review the prevalence and risk factors of work-related musculoskeletal disorders (WMSDs) among healthcare workers (HCWs) in order to ascertain the occupation with the highest susceptibility to WMSD in the health sector. This paper will also review the effective interventions which have been used to prevent WMSDs among HCWs. Design/methodology/approach This study is a literature review of 11 papers related to the prevalence and risk factors of WMSDs and 12 papers about the interventions being used to prevent WMSDs among HCWs. The papers were retrieved from respectable databases such as PubMed, Science Direct, Google Scholar and E-Thesis. Findings Nurses belong to the major group of HCWs who had the highest prevalence of WMSDs compared with other health professionals and other hospital workers. Although there are several interventions being commonly used to prevent WMSD risk factors, some interventions were unsuccessful in the prevention of WMSDs in healthcare tasks. Therefore, it is necessary that future research focuses on the tasks of HCWs that are WMSD risk factors and tries to innovate or redesign ergonomic workstations to prevent those risk factors. Originality/value The expected benefit of this study is to motivate ergonomists to provide appropriate and innovative interventions to ensure health and safety for nurses and other HCWs.

BackgroundAs the proportion of older workers in the U.S. increases, understanding the health and safety needs of an aging workforce is critical, especially in the hazardous and physically demanding construction industry. According to the Bureau of Labor Statistics (BLS), in 2016 the rate of work-related musculoskeletal disorders (WMSDs) in construction was 32.7 per 10 000 full-time equivalent workers, which was 11% higher than the rate for all industries combined. The objective of this study was to examine the rate and cost of WMSDs due to overexertion, the leading cause of WMSDs, among construction workers by age group in Ohio using workers’ compensation claims.MethodsOverexertion related WMSDs allowed claims, submitted to Ohio Bureau of Worker’s Compensation (OBWC) by workers in the construction industry for injuries occurring from 2007–2013 were analyzed to compute rates of allowed claims and claim costs by age group. The American Community Survey of the U.S. Census Bureau was used to determine the proportion of construction workers in each age group in Ohio. For this study, age was categorized as 14–24, 25–34, 35–44, 45–54 and ≥55 years old.ResultsThere were 7434 overexertion related WMSD claims accepted by OBWC for construction workers who were injured due to overexertion in 2007–2013. Workers 35–44 years old experienced the highest claim rate of 7.28 per 1000 for WMSDs due to overexertion. However, the highest mean medical compensation cost for WMSD claims due to overexertion was for construction workers 55 years and older.ConclusionOverexertion-related WMSD claims appear to rise and then fall with age (≥55). There is a need to understand how aging interacts with WMSDs risk factors. Age-specific interventions to reduce WMSDs may help to retain older and skilled workers whose knowledge and experience might otherwise be lost when workers need to leave work because of debilitating WMSDs.

Abstract Background and Purpose. Knowledge, skills, relationships, and attitudes of caring and working hard are all thought to be valued by physical therapists. This article explores how physical therapists see themselves, in light of some of these values, when they experience work-related musculoskeletal disorders (WMSDs). The article also explores the ways in which these values may compete with each other, and it suggests how this may contribute to the onset of WMSDs and to therapists' behavior following a WMSD. Subjects and Methods. Eighteen therapists who had made a career change after a WMSD participated in interviews that were designed to gain insight into the attitudes and beliefs of therapists who had had a WMSD. Results. Participants did not anticipate WMSDs, and they typically believed their physical therapy knowledge and skills would have prevented WMSDs from occurring. They saw themselves as knowledgeable and caring and indicated that these characteristics were highly valued by the profession. Their need to demonstrate these attributes sometimes resulted in behaviors that contributed to the development of their WMSDs and made them worse after their onset. Discussion and Conclusion. The cultural values of physical therapists may make it difficult for them to do their jobs in a way that minimizes the risk of WMSDs. The study identified a potential conflict between the therapists' need to (1) demonstrate their ability to work hard and care for their patients and (2) appear knowledgeable and skilled by remaining injury free.

BACKGROUND: A high prevalence of work-related musculoskeletal disorders (WMSDs) has been reported among flight attendants. Identifying the root causes of these disorders may improve the health conditions of flight attendants and further improve flight safety and service quality. OBJECTIVE: In this study, we aimed to identify WMSD risk factors for a specific population, namely Chinese female flight attendants. METHODS: A two-stage survey including an online questionnaire (46 flight attendants) and a semi-structured interview (16 flight attendants) was used to assess the WMSDs of Chinese female flight attendants. Text analysis tools in NVivo 11 were used to identify the main concerns and risk factors for WMSDs of Chinese flight attendants. RESULTS: In the online questionnaire, more than 86% of the participants reported discomfort in at least one body part. Biomechanical factors, work organizational factors, and psychosocial factors were reported by participants in this study. Chinese passengers were found to have an effect on WMSD development in Chinese flight attendants. CONCLUSIONS: The results of this study suggested that WMSDs are severe problems among Chinese flight attendants. General factors as well as the passenger-relevant factor were identified as the most influential causes of WMSDs.

Objective: This study aims to investigate the one-year prevalence and the associated factors of work-related musculoskeletal disorders (WMSDs) among furniture manufacturing workers in Guangdong, China. Methods: A cross-sectional study of 4181 (2953 males and 1228 females) furniture manufacturing workers was conducted between September 2019 and December 2019. All information about WMSDs was collected by the electronic version of Chinese Musculoskeletal Questionnaires (CMQ). Descriptive statistics and a binary logistic regression model were used to interpret the data. Result: The overall prevalence of WMSDs was 31.57%. The WMSD symptoms most commonly occurred in the neck (16.77%), followed by the shoulders (14.90%), ankles/feet (14.64%), hands/wrists (13.30%), upper back (11.48%), and lower back (10.95%). Multiple logistic regression analysis revealed that several individual, labor organization, and ergonomics-related factors conferred significant risks to WMSDs at different body sites. Conclusions: WMSDs remain the major occupational health problem for furniture manufacturing workers. Hence, some effective and feasible protective measures for furniture manufacturing workers are required in order to alleviate the health burden caused by WMSDs.

Full textAbstract:
AbstractWork-related musculoskeletal disorders (WMSDs) represent approximately one third of workers' compensation costs in US private industry, yet estimates of acceptable exposure levels for forceful and repetitive tasks are imprecise, in part, due to lack of measures of tissue injury in humans. In this review, the authors discuss the scope of upper-extremity WMSDs, the relationship between repetition rate and forcefulness of reaching tasks and WMSDs, cellular responses to injury in vivo and in vitro, and animal injury models of repetitive, forceful tasks. The authors describe a model using albino rats and present evidence related to tissue injury and inflammation due to a highly repetitive reaching task. A conceptual schematic for WMSD development and suggestions for further research are presented. Animal models can enhance our ability to predict risk and to manage WMSDs in humans because such models permit the direct observation of exposed tissues as well as motor behavior.

Full textAbstract:
Background/Aim: Work-related musculoskeletal disorders (WMSDs) develop due to exposure to physical and psycho-social factors in the work environment. The diagnostic criteria and prevalence of WMSDs are not well established. In this study, we aimed to determine which WMSDs occur in automotive industry workers and what the underlying risk factors may be.
 Methods: A cross-sectional study was designed that included 200 automotive industry workers who were diagnosed with a WMSD by physical and radiological examination in the physical therapy and rehabilitation outpatient clinic in the past year. We recorded demographic data, risk factors and WMSD diagnosis names for the patients.
 Results: In our study, the most common diagnosis was low back disorder (66.5%), followed by neck and shoulder (58%) and upper extremity (23%) disorders. There was a statistically significant increase in the occurrences of shoulder-neck diseases, upper extremity, and low back-lower extremity diseases in workers with inappropriate posture (P < 0.001). Workers who exerted heavy effort or performed repetitive motions were statistically more likely to experience upper extremity disorders (P < 0.001) as well as low back-lower extremity disorders (P = 0.020 and P < 0.001, respectively); there was no statistically significant change in the incidence of shoulder and neck diseases with heavy effort (P = 0.538).
 Conclusion: WMSD is a serious health and economic problem. In our study, we found that low back and lower extremities and neck and shoulder problems are the most common types of WMSDs in individuals working in the automotive sector. Not using proper posture while working causes health problems in the shoulders, neck, upper extremities and low back and lower extremities. Employees in this sector should be encouraged to use good work ergonomics.

Full textAbstract:
Background. Work-related musculoskeletal disorders (WMSDs) have a negative impact on quality of life, and dentists are at risk of WMSDs due to the nature of work being static, repetitious, and for a long duration. The study was aimed at measuring the prevalence and distribution of work-related musculoskeletal disorders and determining the risk factors associated with affliction among Pakistani dentists. Methods. An online cross-sectional survey was conducted using a validated questionnaire consisting of four sections. The first section had questions related to sociodemographic information, the second section had questions that assessed the intensity and frequency of musculoskeletal pain (MSP), third section questions were concerned with the effect of MSP on the respondents’ daily life, while the last section contained questions on whether they perceived their work in the dental clinic as a cause of their pain. Chi-square and one-way ANOVA tests were used for the analysis of the data in SPSS-23. Results. A total of 600 completely filled questionnaires were received with a response rate of 76.4%, and about 87% of the dental practitioners had some sort of MSD. The intensity and frequency of WMSDs were statistically significant ( p < 0.05 ) in association with all the sociodemographic characteristics. The lower back area was the most reported site of WMSD pain (51.3%) followed by the neck/upper back (21.3%) and shoulder (17.6%). The site of pain was statistically significant ( p < 0.05 ) in association with all the sociodemographic characteristics except gender ( p = 0.11 ). A majority of participants (95.4%) had sought medical treatment and taken sick leaves (70%) due to WMSDs pain during their life. Participants attributed a number of working years and working posture as the two main reasons behind WMSDs. Conclusion. Considering the high prevalence of WMSDs among dentists, preventive strategies that minimize the occurrence of WMSDs should be adopted by dental professionals. The impact of WMSDs can be reduced by maintaining good posture, taking breaks and rest in between work, doing regular exercise, and improving the work environment.

Background. The objective of this study is to determine the prevalence and predictors of work-related musculoskeletal disorders (WMSDs) among a sample of commercial minibus drivers in the Accra Metropolis of Ghana. Methods. The participating drivers (n=148) were recruited from various lorry terminals and assessed by using a semistructured questionnaire that included the Nordic Musculoskeletal Questionnaire (NMQ). Results. Of the 148 drivers, 116 (78.4%) reported having WMSDs during the previous 12 months. The prevalence of the various WMSD domains was low back pain (58.8%), neck pain (25%), upper back pain (22.3%), shoulder pain (18.2%), knee pain (14.9%), ankle pain (9.5%), wrist pain (7.4%), elbow pain (4.7%), and hip/thigh pain (2.7%). Multiple logistic regression analysis adjusted for possible confounders showed that less physical activity (OR = 4.9; 95% CI = 1.5–16.5; P=0.010), driving more than 12 hours per day (OR = 2.9; 95% CI = 1.1–7.8; P=0.037), and driving at least 5 days per week (OR = 3.7; 95% CI = 1.4–9.4; P=0.007) were significantly associated with WMSDs among this cohort of drivers. Conclusion. These modifiable factors may be targets for preventive strategies to reduce the incidence of WMSDs among occupational minibus drivers in Ghana.

Full textAbstract:
A recent development in ergonomics research is using machine learning techniques for risk assessment and injury prevention. Bus drivers are more likely than other workers to suffer musculoskeletal diseases because of the nature of their jobs and their working conditions (WMSDs). The basic idea of this study is to forecast important work-related risk variables linked to WMSDs in bus drivers using machine learning approaches. A total of 400 full-time male bus drivers from the east and west zone depots of Bengaluru Metropolitan Transport Corporation (BMTC), which is based in Bengaluru, south India, took part in this study. In total, 92.5% of participants responded to the questionnaire. The Modified Nordic Musculoskeletal Questionnaire was used to gather data on symptoms of WMSD during the past 12 months (MNMQ). Machine learning techniques including decision tree, random forest, and naïve Bayes were used to forecast the important risk factors related to WMSDs. It was discovered that WMSDs and work-related characteristics were statistically significant. In total, 66.75% of subjects reported having WMSDs. Various classifiers were used to derive the simulation results for the frequency of pain in the musculoskeletal systems throughout the last 12 months with the important risk variables. With 100% accuracy, decision tree and random forest algorithms produce the same results. Naïve Bayes yields 93.28% accuracy. In this study, through a questionnaire survey and data analysis, several health and work-related risk factors were identified among the bus drivers. Risk factors such as involvement in physical activities, frequent posture change, exposure to vibration, egress ingress, on-duty breaks, and seat adaptability issues have the highest influence on the frequency of pain due to WMSDs among bus drivers. From this study, it is recommended that drivers get involved in physical activities, adopt a healthy lifestyle, and maintain proper posture while driving. For any transport organization/company, it is recommended to design driver cabins ergonomically to mitigate the WMSDs among bus drivers.

Introduction Work-related musculoskeletal disorder (WMSD) is a leading causes of occupational injury and disability among drivers and workers in the transport industry. This study evaluated the ergonomically assessed WMSD and its determinants among Nigerian commercial mini bus drivers (BD) and mini bus conductors (BC) Method A total of 379 participants (BD = 200, BC = 179) were purposively sampled for this exploratory cross-sectional study. Participants’ WMSD and work related variables were respectively assessed using the standardized Nordic questionnaire and a content-validated, Driving Work Station Assessment (DWSA) form. Data were analyzed descriptively and inferentially using chi-square and logistic regression. The level of significance was set at α = 0.05. Results The participants were aged between 20 and 66 years, with a mean age of 33.26±10.76years (BD = 38.42±10.22years, BC = 27.50±8.13years); most of whom consumed alcohol (84.4%) and experienced severe job stress (73.4%). There was a high prevalence (95.8%; BD = 94.5%, BC = 97.8%) of WMSDs, the lower back (66.8%) and upper back (54.1%) had the highest regional prevalence of WMSD. The BC (BC vs BD) had significantly (p<0.05) higher prevalence of Neck (47.7% vs 21.5%) and upper back (80.4% vs 30.5%) WMSDs. Conversely, the BD (BD vs BC) had significantly (p<0.05) higher prevalence of low-back (85.0% vs 46.4%), knee (25.0% vs 9.5%), elbow (11.5% vs 3.9%), and wrist (10.5% vs 3.4%) WMSD. There was a significant association between WMSD and each of work duration (X2 = 11.634, p = 0.009), work frequency (X2 = 8.394, p = 0.039), job dissatisfaction (X2 = 10.620, p = 0.001) and job stress (X2 = 16.879, p = 0.001). Working beyond 4days/week (OR = 10.019, p = 0.001), job dissatisfaction (OR = 1.990, p = 0.031), constrained working postures (OR = 5.324, p = 0.003) and fatigue (OR = 4.719, p = 0.002) were the predictors of WMSD. Conclusion Job stress, work duration and work frequency, posture and fatigue are important determinants of WMSDs among mini bus drivers and their assistants in Nigeria. Ergonomics training intervention for this population is recommended.

Highlights Neck and shoulder discomfort found to be most prevalent in veterinary technicians. REBA posture analysis identifies areas of significant risk and provides a benchmark for improvements. Patient restraint and handling put veterinary technicians at significant risk for musculoskeletal disorders. Continuous improvement through the implementation of engineering and administrative controls is mandatory. Abstract. Research addressing work-related musculoskeletal disorders (WMSDs) among veterinary technicians is limited. Veterinary technicians are exposed to several activities that require lifting and the adoption of non-neutral postures associated with WMSDs. It is essential to design interventions aimed at reducing WMSDs in this population. The goal of this study was to identify typical, prevalent work tasks that pose high ergonomic risk factors to veterinary technicians, as well as to determine the WMSD risk associated with the work tasks identified in order to implement interventions. A small-animal veterinary clinic in central Wisconsin was contacted for this study. Nine veterinary technicians and assistants participated in assessing musculoskeletal symptoms and identifying tasks with ergonomic risk factors. The tasks with a high count of risk factors were evaluated using the Rapid Entire Body Assessment (REBA). All participants in this study experienced musculoskeletal discomfort in five or more body regions. They also reported being unable to perform work over the last 12 months due to WMSDs on shoulders, ankles, and feet (33%, n=3), neck and lower back (22%, n=2), and wrists, hands, hips, thighs, and knees 11% (n=1). One of the respondents reported no discomfort over the last seven days, while eight of them indicated discomfort in three or more body areas. Restraining and handling animals, sedation and recovery, and dental procedures were chosen for REBA analysis. Restraining and handling animals had a high-risk REBA score (ranging from 8 to 10). Sedation and recovery had a low to medium-risk REBA score (ranging from 3 to 5). Dental procedure recovery had a low to very high-risk REBA score (ranging from 2 to 11). Our findings suggest that most veterinary technicians come to work experiencing musculoskeletal discomfort and are exposed to significant WMSD risk levels when performing common tasks. This job assessment allows us to recommend administrative and engineering controls to reduce the risk of WMSDs associated with high-risk tasks. Keywords: Ergonomic risk factors, Musculoskeletal symptoms, Rapid Entire Body Assessment (REBA), Veterinary technicians, Work-related musculoskeletal disorders (WMSDs).

To assess the prevalence of upper extremity work-related musculoskeletal disorders (WMSDs) among surgical device mechanics compared to a control group, a total of 70 employees were included and assigned to three occupational groups (grinders, packers, and control). Personal factors, work exposure, manual skill, and complaints were assessed by two self-administered questionnaires and an industry test. WMSDs were diagnosed in a standardised clinical examination. The two-one-sided t-tests (TOST) procedure was used to test the clinical equivalence of the respective grinding and packaging groups vs. the control group in terms of the Disabilities of the Arm, Shoulder and Hand (DASH) score. Thirty-nine study participants (56%) experienced at least one WMSD at the elbow, forearm, and/or wrist, mainly with signs of epicondylitis and nerve entrapment at the medial elbow. The risk of grinders developing upper extremity WMSD was about 2.5-times higher and packers had an 8.6-fold higher risk of a clinically relevant DASH > 29 compared to the control group. However, these differences were not statistically significant. The groups were also proven to be clinically equivalent in terms of DASH score. Surgical device mechanics do not seem to have worse DASH values or be at higher risk of upper limb WMSDs compared to a control group. This is the first study to analyse and compare different workplaces in this industry that are also common in other industries.

Full textAbstract:
BACKGROUND: Work-related musculoskeletal disorders have become a great health issue among dentists. However, it is never been examined among dentists in the State of Kuwait. OBJECTIVES: The purposes of this study were to define the prevalence of work-related musculoskeletal disorders (WMSD) among dentists in the State of Kuwait, to identify risk factors for WMSD, and to explore relationships between WMSD and absenteeism/productivity. METHODS: A descriptive cross-sectional design was used in this study. A self-administered questionnaire was distributed to dentists at government, private, and academic dental clinics. RESULTS: A total of 186 questionnaires were returned (80% response rate). The results showed that 88 (47%) of responding dentists experienced WMSDs. Dentists self-reporting WMSD were older (36.4 (10.3) years vs. 32.6 (9.33); P = 0.01), in practice longer (11.7 (10.4) years vs. 8.2 (8.4); P = 0.013), and worked longer hours (34.9 (10.6) hours vs. 30.4 (11.5); P = 0.08) than dentists not reporting WMSD. A significant association was found between rating of pain and lost days from work (x2 (10, n = 85) = 20.96, ρ = 0.021). CONCLUSIONS: Dentists’ occupational procedures expose their bodies to prolonged and awkward postures, thereby subjecting the dentists to unnatural forces and stresses on crucial movement and functioning joints. Cumulative exposures to such postures lead to WMSDs. Generally, WMSD has a considerable impact on the health and economic status of the individual, family, and workplace. WMSD increases absenteeism and reduces productivity.

This paper aimed to demonstrate the contribution of the research performed by the musculoskeletal disorders (MSD) Research Axis group of the Quebec Occupational Health and Safety Research Network towards better understanding of work-related MSD (WMSD) development and prevention. Although the group targets its work to the Quebec population, its work has significant impact around the world, placing MSD axis members and knowledge and expertise created in Quebec on the international map. Results from the contribution of members are relevant, primarily in the demonstration of the implication of physical workload as well as organizational and psychosocial work-related factors in the development of WMSDs. Also, members have demonstrated that gender, sex, social class, age and ethno-cultural groups interact in various ways with WMSD determinants. Efforts are devoted towards improving understanding of the physiological responses linked with MSDs, which could also lead to new workplace practices in rehabilitation. The group emphasizes the integration of prevention procedures from the design stage to the workplace intervention. Members have proposed research-based tools for best practices at work and also an original conceptual model as a key, novel element of a theoretical conceptualization of WMSDs. Moreover, the group focuses on improving WMSD surveillance, using multiple sources of information, providing information on newly identified health risks and developing new methods of assessing risk in order to effectively prevent disability in the working population. Finally, results from research of the MSD axis group have implications for orienting legal processes, improving legal recognition of MSDs as occupational diseases, and contributing to the evolution of legal thinking. However, much remains to be done. To that end, the group plans and encourages new initiatives for further advancement. In conclusion, the originality of the work places the group in a favourable position to address the complexity underlying WMSDs, combining expertise that enriches fundamental, clinical and population-based research.

BACKGROUND: Work-related musculoskeletal disorders (WMSDs) represent a significant problem for nurses. It is thus important to investigate nurses’ WMSDs prevalence and comprehensive predictors including motor, mental, and lifestyle factors. OBJECTIVES: To investigate the prevalence and predictors of lower quadrant WMSDs among Jordanian nurses. METHODS: A cross-sectional design, using self-administered questionnaires, was utilized. Outcome measures included Nordic Musculoskeletal Questionnaire (NMQ), Depression Anxiety Stress Scale (DASS21), Pittsburgh Sleep Quality Index (PSQI), sociodemographic data, and self-reported work ergonomics. Descriptive analyses were used to determine lower quadrant WMSDs prevalence and regression analyses were used to assess their predictors. RESULTS: A total of 597 nurses participated in the study. Twelve-month prevalence of lower quadrant WMSDs were 77.4% in lower back, 22.3% in hips, 37.5% in knees, and 28.5% in ankles and feet. Older age, longer years of experience, high workload, poor work habits and ergonomics, high physical activity level, availability of patient handling equipment, handling policies, stress, and anxiety were significant predictors (p< 0.05) of lower quadrant WMSDs. CONCLUSIONS: Jordanian nurses have a high prevalence of lower quadrant WMSDs. Many modifiable risk factors of WMSDs were identified. Future studies need to design effective treatment and preventive strategies for nurses’ WMSDs to improve their work efficiency and wellbeing.

Introduction: Healthcare professionals, especially those with in direct contact of patient are at the highest risk of work-related musculoskeletal disorders (WMSDs), physical therapists being one of them. Aim: Our aim was to review current knowledge relating to the prevalence, risk factors and prevention of WMSDs among physiotherapists. Method: Google Scholar and PubMed were searched for terms relating to WMSDs in Physiotherapists from inception to 2021. Result: The prevalence of WMSDs among Physiotherapist was high, with the lower back as the most frequently affected followed most often by the neck, upper back and shoulders. Knee joint was commonly affected joint in lower extremity. Multiple risk factors have been found responsible for WMSDs in physiotherapist and some of them are modifiable. Conclusion: Implementing preventive strategies for WMSDs in early stage of a physiotherapist’s career may help to prevent WMSDs and maintain good quality of treatment for patients. Keywords: Pain, Musculoskeletal disorders, Ergonomics, Prevention.

Full textAbstract:
Plumbing work is more manually driven in low-and-middle income countries (LMICs), and the prevalence of work-related musculoskeletal disorders (WMSDs) among workers who engage in plumbing in LMICs may be worse than earlier reports from developed countries. This study aimed to assess the prevalence, pattern and risk factors for work-related musculoskeletal disorders (WMSDs) among Nigerian plumbers. A total of 130 consenting plumber participated in this cross-sectional study. The Nordic Musculoskeletal questionnaire and the Job Factor Questionnaire were used to assess information on prevalence and pattern of WMSDs; and perceptions regarding work-related risks factors for WMSDs. Descriptive (mean, frequency, range, percentage and standard deviation) and inferential (Chi-square) statistics were used to analyze data. Alpha level was set at p<0.05. The mean age of the respondents is 36.56 ± 10.418 years. The mean years of experience and working hours per day are 14.15 ± 9.161 years and 8.28 ± 2.512 hours. Job characteristics were mostly installation of pipes and fixtures (99.2%), equipment and fixtures prior to installation (96.9%), and testing of plumbing system for leaks (88.5%). 12-month and 7-day prevalence of WMSDS were 84.6% and 50.8%. Low-back (63.8%), neck (55.4%) and knee (50%) were the most affected body sites. Having WMSDs limits normal activities involving the low-back (32.3%), knee (25.4%) and neck (23.8%). There was significant association between 12-month prevalence of WMSDs and use of saws and pipe cutters (χ2 = 4.483; p = 0.034), while sites of affectation had significant association with 12-month and 7-day prevalence of WMSDs (p<0.05) respectively. Nigerian plumbers have a high prevalence of WMSDs affecting most commonly the low back, neck and knee. Plumbing job factors pose mild to moderate risk to developing WMSDs, and use of saws and pipe cutters significantly influence WMSDs.

BACKGROUND: Work-related musculoskeletal disorders (WMSDs) represent a significant health challenge facing nurses. However, very few studies investigated the prevalence of WMSDs among nurses and their predictors comprehensively using a valid and reliable set of standardized outcome measures. OBJECTIVE: This study aimed to investigate the prevalence WMSDs of upper quadrants and their predictors among registered nurses in Jordanian hospitals. METHODS: A cross-sectional study recruited 597 registered nurses from different hospitals in Jordan. A self-administered survey distributed in targeted hospitals wards. Outcome measures included Nordic Musculoskeletal Questionnaire (NMQ), Depression Anxiety Stress Scale (DASS), Pittsburgh Sleep Quality Index (PSQI), International Physical Activity Questionnaire (IPAQ), sociodemographic data, and manual handling and work habits. Prevalence of musculoskeletal complaints was reported using descriptive analysis. Logistic regression analyses were used to identify predictors of WMSDs at each upper quadrant body site. RESULTS: Twelve-month WMSDs prevalence was the highest at the neck (61.1%), followed by the upper back (47.2%), shoulders (46.7%), wrist and hands (27.3%), and finally at the elbow (13.9%). Being a female, poor sleep quality, high physical activity level, poor ergonomics, increased workload, and mental stress were significant predictors of increased upper quadrant WMSDs among nurses. CONCLUSIONS: Upper quadrant WMSDs among nurses in Jordan are highly prevalent. Identified significant predictors of these WMSDs should be given full consideration by clinicians and health policymakers. Future studies are needed to reveal the progressive nature of upper quadrant WMSDs and strategies to modify their risk factors.

Full textAbstract:
Objectives: Musculoskeletal disorders (MSDs) are the most common occupational health problem accounting for a larger number of compensation days and disability among workers. An invisible workforce of female domestic workers (FDWs) is involved in back-breaking jobs in the informal job sectors, and yet, there are no studies to quantify their work-related MSD’s (WMSDs). The objective of the study is to determine the prevalence of WMSDs among FDWs employed at private houses in Bengaluru, South India. Material and Methods: A cross-sectional study was conducted among 408 randomly selected FDWs with a comparative group. The trained interviewer assessed WMSDs using a standardized Nordic Musculoskeletal questionnaire and psychosocial distress using the general health questionnaire–12. Results: A high prevalence of WMSD was reported in the neck (19.6%), shoulder (23.8%), elbow (12%), upper back (31.9%), and ankle (26%) in domestic workers than the non-domestic workers. Age above 37 years (AOR: 1.77, 95% CI: 1.03–3.06), house cleaning ([>1715 h/year – AOR: 1.30, 95% CI: 0.60–2.84] [1714–555 h/year – AOR: 1.30, 95% CI:0.66–2.59]), and clothing ([Care >1460 h/year – AOR: 2.44, 95% CI: 1.12–5.35] [109–1459 h/year – AOR: 1.98, 95% CI: 0.95–4.10]) were factors associated with neck pain in FDW. Moreover, work experience of more than 10 years (AOR: 2.10, 95% CI: 1.32–3.34) and distress (AOR: 2.13, 95% CI: 1.25–3.61) was a factor associated with lower back pain in FDW. Conclusion: FDWs are substantially affected by WMSDs in the neck and lower back due to house cleaning and clothing care tasks performed in the workplace setting, respectively.

Objective. To investigate the status of work-related musculoskeletal disorders (WMSDs) in nurses working in the hospitals in Xinjiang Uygur Autonomous Region. Methods. The prevalence of WMSDs since working and in the previous 12 months was evaluated using self-administrated modified musculoskeletal questionnaire based on North European questionnaire. In this cross-sectional study, 6674 nurses involved in the nursing profession were selected from 16 hospitals using the stratified cluster sampling method. Results. The most commonly affected regions by WMSDs were lower back, neck, shoulder, and back, with an annual prevalence of 62.71%, 59.77%, 49.66%, and 39.50%, respectively. Statistical differences were noticed in the annual prevalence of WMSDs in those with different ages (P<0.01) and working durations (P<0.01). Logistic regression analysis indicated that the following risk factors were associated with the prevalence of WMSDs: working duration of ≥6 years; working in the Emergency Department, Department of Anesthesia, or Supply Room; night shift of more than once, working duration of >40 hrs per week; poor health status; and feeling of fatigue. Rest time of >10 min and no history of WMSDs were the protective factors of WMSDs. Conclusions. Shift and working/rest duration was closely related to WMSDs.

OBJECTIVE: This study aimed at investigating the relationships between health and work-related musculoskeletal disorders (WMSDs) in dentists, and the relationship with socio-demographic, work and health variables.METHODS: We conducted a cross-sectional study of 204 dentists who work in public clinics in the state of São Paulo, Brazil. We used a self-administered survey that included questions on sociodemographic and health aspects, work-related factors, and the Nordic questionnaire.RESULTS: WMSDs were often reported in the neck, shoulder, lower back, and hand/wrists. Logistic regression analysis revealed that there was a correlation between reports of WMSD in the neck and age (OR = 9.48) and health problems (OR = 6.71). Moreover, strong associations were found between MSDs in the shoulders, gender (OR = 5.88) and breaks between appointments (OR = 4.17).CONCLUSION: We concluded that the health problems diagnosed, work-related activities and gender contributed to musculoskeletal disorders in dentists in this clinic.

Full textAbstract:
Although physical factors are accepted as risks in the development of work related musculoskeletal disorders (WMSDs), psychosocial factors may explain some of the remaining differences in susceptibility to WMSDs. The following study examined the effects of two psychosocial factors, mental workload and time pressure, on typing performance, perceived workload, and key strike force while typing. The majority of the key strike force measures increased with increases in time pressure and mental workload. Perceived overall workload (as measured using SWAT) increased with mental workload and time pressure, and typing performance decreased. Additionally, gender, locus of control, and perceived stress level did not influence outcomes. Physical risk factors may be mediated by psychosocial factors to increase risk for WMSD development in the upper extremities. Therefore, both physical and psychosocial aspects of work environments should be considered when designing jobs and work tasks to prevent injuries and improve productivity.

Full textAbstract:
Work-related musculoskeletal disorders (WMSDs) persist as the leading occupational injury, accounting for nearly half of nurses’ total occupational injuries. Musculoskeletal pain is a known cause of sleep disruption, and individuals with WMSDs that interfere with sleep often report more pain. Evening chronotype has been associated with poor sleep among nurses. However, the associations among chronotype, sleep, and WMSDs are still unclear, and were explored in the present study. A cross-sectional survey was administered to 397 nurses, with 47.4% reporting WMSDs. Robust Poisson regression modeling suggested that evening type (PR = 1.32, p < .05), prolonged sleep onset latency (PR = 1.37, p < .05), and using sleep-promoting substances (PR = 1.35, p < .01) were associated with increased risk of WMSDs among nurses, after adjusting for shift work, regular exercise, body mass index, and other covariates. This study suggests that well-designed evidence-based nonpharmacological interventions to improve sleep may reduce the risk of WMSDs among nurses.

Full textAbstract:
Little is known about how nursing assistants (NAs) perceive the nature of their work and how their work contributes to work-related musculoskeletal disorders (WMSDs). This qualitative study addressed these gaps. Twenty-four NAs with WMSDs working in four nursing homes participated in semistructured focus group interviews. Their WMSDs were not limited to the lower back but involved several body parts. The risk factors for WMSDs included physical, psychosocial, organizational, and personal factors as well as coworkers and clients. However, it is the synergistic effects of long work hours without sufficient rest, work even with musculoskeletal pain because of staff shortages, ineffective management with insufficient prework training and inadequate equipment maintenance, and an aging workforce with strong commitment to resident care that play a crucial role in WMSDs among NAs working in nursing homes. The study found that multidimensional intervention strategies using engineering, administrative, and personal controls should be developed to reduce WMSDs among NAs working in nursing homes.

Full textAbstract:
Available data show that work stress and work-related musculoskeletal disorders (WMSDs) are the leading occupational health burdens in Member States of the European Union. Cross-sectional data do no provide a clear indication of the impact of work stress upon WMSDs. Studies have used different indicators for stress and this makes comparison between them more difficult. Similar workplace risk factors, including physical and psychosocial, seem to be associated with work stress and WMSDs. Stress has been implicated in the pathology of WMSDs but many hypotheses require further investigation. There is some epidemiological evidence to support work stress reactions as a predictor of WMSDs and a weighted reciprocal relationship may also exist between these two health problems. However, more longitudinal studies are required to clarify this issue.

Background. Work-related musculoskeletal diseases (WMSDs) have been associated with job burnout. Currently, few studies have investigated the relationship between job burnout and WMSDs among coal miners. Methods. In this cross-sectional study, 1,325 staff were selected from 6 coal mining companies using a stratified cluster sampling method. The Chinese version of “Musculoskeletal Questionnaire” and “Occupational Burnout Scale” were used to investigate the link between WMSDs and job burnout. Logistic regression was conducted to analyze the factors influencing WMSDs. Results. A total of 1,500 questionnaires were distributed, with a response rate of 88.33%. The prevalence of WMSDs in coal miners was 65.58%, while the prevalence of total, mild, moderate, and severe burnout were 90%, 39.77%, 43.77%, and 6.49%, respectively. The average score for job burnout was 50.78 ± 11.93. The prevalence of WMSDs among coal miners varied significantly with the length of service ( χ 2 = 14.493 , P = 0.001 ), type of work ( χ 2 = 11.438 , P = 0.022 ), shift system ( χ 2 = 6.462 , P = 0.040 ), and annual income ( χ 2 = 6.315 , P = 0.043 ). The proportions of male coal miners with moderate and severe burnout were 45.1% and 6.8%, respectively, which were higher compared with 28.6% and 2.9%, respectively, for women. The proportion of male coal miners with mild burnout was 38.1%, which was lower compared with 59.0% for women P < 0.05 . Coal miners who work more than two shifts had the highest burnout, while those who work day shifts had the lowest burnout P < 0.001 . The prevalence of WMSDs in the severe burnout group and in 9 body locations was significantly higher than that in other burnout groups P < 0.001 . Logistic regression results showed that length of service, type of work, annual income, and burnout level are associated with WMSDs among coal miners P < 0.05 . Conclusions. The prevalence of job burnout and WMSDs among coal miners in Xinjiang is relatively high. Job burnout is a risk factor for WMSDs among coal miners.

A wide range of endpoints and methods of analysis can be observed in occupational health studies in the context of work-related musculoskeletal disorders (WMSDs). Comparison of study results is therefore difficult. We investigated the association between different clinical endpoints and the presence of upper extremity WMSDs in a healthy working population. Furthermore, the influence of socio-demographic, work-related, and individual predictors on different endpoints was examined. Two self-administered questionnaires were distributed to 70 workers and employees. In addition, a standardized physical examination and an industry test were performed in this cross-sectional study. Correlations between WMSDs and clinical endpoints were analyzed with the Spearman method and prediction ellipses. Multiple regression models were used to study the strength of associations with a pre-defined set of potential influencing factors. The prevalence of WMSDs was 56% (39/70). Disabilities of Arm, Shoulder, and Hand (DASH) score/pain under strain showed the strongest correlations with WMSDs. When analyzing the correlation between WMSDs and pre-selected predictors, none of the predictors could be identified as a risk factor. The DASH score remains a close candidate for best surrogate endpoint for WMSDs detection. Standardized analysis methods could improve the methodological quality of future occupational health studies.

Purpose The demanding nature of firefighting exposes firefighters to unprecedented work stress and work-related musculoskeletal disorders (WMSDs). Even though relationships among work demand, work stress and WMSDs have been examined, the mediating role of work stress in the relationship between work demand and WMSDs requires more attention, particularly among emergency workers. The purpose of this paper is to therefore assess the mediation role of firefighters’ work stress in the pathway of work demand and WMSDs. Design/methodology/approach A quantitative research design was used. Convenient sampling was employed to select 320 firefighters from the Greater Accra region of Ghana. Data were analyzed using descriptive, correlation and regression. Findings The findings revealed that work demand and stress significantly affect WMSDs. Also, work demand has a significant positive effect on work stress. It was further found that work stress partially mediates the relationship between work demand and WMSDs. Research limitations/implications The usage of cross-sectional data limits the strength of causality and observation of changes within units of observation over time, hence the need to use longitudinal data in future studies. Originality/value The novelty of this study lies in the revelation of the influence of stress in the pathway of work demand and WMSDs among emergency professionals, using an African lens.

ObjectiveThis study aims to define appropriate domains and items for the development of a self-administered questionnaire to assess the risk of developing work-related musculoskeletal disorder (WMSD) and the risk of its progression to chronicity.DesignLiterature review and survey study.Setting and participantsA literature review and a two-round interview with 15 experts in musculoskeletal pain were performed to identify the available domains for WMSD assessment.Interventions and outcomeTo ensure quality, only validated questionnaires were included for the Delphi process. A three-round Delphi method, with three round steps, was used to select the most pertinent and relevant domains and items.ResultsNine questionnaires were identified through the expert discussion and literature review, comprising 38 candidate domains and 504 items. In the first round of the Delphi group, 17 domains reached more than 70% agreement and were selected. In the second round, 10 domains were rejected, while 11 were selected to complete the pool of domains. In the third and final round, 89 items belonging to 28 domains were defined as significant to develop a WMSDs risk assessment questionnaire.ConclusionsNo specific risk assessment questionnaires for WMSDs were identified from the literature. WMSD risk of presence and chronicity can be defined by an assessment tool based on the biopsychosocial model and the fear-avoidance components of chronic pain. The present study provides the formulation and operationalisation of the constructs in domains and items needed for developing and validating the questionnaire.

Background According to Washington State workers’ compensation data, construction as an industry ranked first in its compensable claims rate of work-related musculoskeletal disorders (WMSD) injuries (Anderson, Adams, Bonauto, Howard, & Silverstein, 2015). Many current physical job assessment tools available for ergonomics practitioners to evaluate work-related musculoskeletal disorder risks of the back, shoulder, hand/wrist and knee are mostly of general purposes. This project sought to identify risk factors pertinent to given industries. The construction industry is used as an example in this demonstration. Approach Four hundred thirty-six construction employees from sixteen companies in the State of Washington were observed and evaluated using commonly used exposure assessment tools: Washington State Checklists (Washington State Department of Labor and Industries, 2004a, b), Strain Index (Moore & Garg, 1995), American Congress of Governmental Industrial Hygienists Lifting Threshold Limit Values (ACGIH, 2005), Liberty Mutual Manual Materials Handling Guidelines (Snook & Ciriello, 1991), Quick Ergonomics Checklist (David et al, 2005; David et al, 2008), and the European Union Vibration Directives (EU, 2002). The physical risk factors that were evaluated are those that have been associated with WMSDs. These risk factors included: awkward postures of the back, shoulder, hand/wrist; lifting; pushing, pulling, carrying; high hand forces (pinching, griping); highly repetitive motions of the hand/wrist; repeated impacts of the hand or knee; vibration (whole body, hand); and any specific tasks with potential WMSD risks but were otherwise not covered in any of the common assessment tools. Following the results of the exposure assessments, a comprehensive physical job evaluation checklist was created by retaining items sensitive to differentiate levels of risks within jobs in the construction industry. From our job evaluations, WMSD risk factors may not be the same between industry groups and as such, industry-specific tools may simplify the evaluation process by focusing on unique exposures. The final Physical Job Evaluation Checklist is currently presented in the form of a spreadsheet available for download and use ( www.lni.wa.gov/Safety/Research/Wmsd/WMSD2010.asp ). Accompanying reference guide is also available to provide instructions how data fields can be obtained or measured. The user can print out a paper form first, record the assessment at a job site, then enter the necessary data into the spreadsheet. The algorithm then generates all the evaluation reports and highlight areas that should receive attention. The goals are to raise general awareness of industry-specific physical factors that contribute to work-related musculoskeletal disorders (WMSDs), and help identify specific aspects of the job that pose a risk for back, shoulder, hand/wrist and knee injury common in the construction industry. Using the Physical Job Evaluation Checklists can help prioritize injury prevention efforts by identifying the jobs, or the aspects of the job that pose the greatest risk of injury. It is also possible to evaluate the impact that proposed jobsite changes have on WMSD risk (before and after exposures). And finally, it is possible to compare exposures between workers performing the same or different tasks. Limitation Due to the study design, the Physical Job Evaluation Checklist IS NOT intended to predict the occurrence of WMSDs or to provide guidance or suggestions on how to mitigate exposure to risk factors of WMSDs.

Introduction. Globally, work-related musculoskeletal disorders (WMSDs) have resulted in occupational disability and injury. Of these, restaurant workers are among the high-risk professionals usually affected by WMSDs. In Ethiopia, evidence on the burden of musculoskeletal disorder and contributing factors among restaurant workers were very limited. Therefore, this study was aimed at assessing the prevalence of self-reported WMSDs and contributing factors among restaurant workers in Gondar city, northwest Ethiopia, 2020. Methods. An institutional-based cross-sectional study was conducted from February 2020 to March 2020 among restaurant workers in Gondar city. A two-stage sampling technique was used to choose 633 study subjects. A structured Nordic questioner was used to collect the data. Data was entered into EpiData version 3.1 and exported to Stata version 14.0 for analysis. Both bivariable and multivariable logistic regression analyses were computed. An adjusted odds ratio with a 95% confidence interval was used to measure the association between WMSDs and independent variables. In the multivariable analysis, a P value of <0.05 was used to declare a statistically significant association. To check the goodness of fit, the Hosmer and Lemeshow test was used. Results. The prevalence of WMSDs among restaurant workers in the past 12 months was 81.5% [95% CI (78.18–84.44)]. Attending primary education [AOR: 2.14, 95% CI (1.17–3.90)], attending secondary education [AOR: 1.71 (1.02–2.86)], and job satisfaction [AOR: 1.90, 95%CI (1.13–3.19)] were significantly associated with WMSDs. Conclusion. In this study, the prevalence of WMSDs among restaurant workers was high. The upper back, lower back, elbow, and wrist were the most affected body parts. Age above 30 years, educational status being primary and secondary, and being dissatisfied by their job were positively associated with a high prevalence of WMSDs.

Work-related musculoskeletal disorders (WMSDs) are a common health problem in many industries. National Occupational Research Agenda (NORA) is a research framework for the nation and for the National Institute for Occupational Safety and Health (NIOSH). The process for developing the 2016-2026 NORA for the Prevention of WMSDs is presented along with the identified five critical areas of research: (1) defining the incidence and impact of MSDs; (2) understanding the risk factors for WMSDs; (3) describing the underlying mechanism of MSDs; (4) developing and evaluating interventions to prevent MSDs and limit disability due to MSDs; and (5) disseminating and implementing interventions to prevent WMSDs and limit disability. The research agenda is being promoted by the NORA Musculoskeletal Health Council which is comprised of 32 volunteer members from universities, businesses, professional societies, worker organizations and government agencies. Stakeholders for the prevention of WMSDs are encouraged to collaborate with the NORA Musculoskeletal Health Council on addressing the research agenda.

The performance of workers is a very important factor that could affect the overall productivity result. In the industrial repetitive task, the performance of direct workers has a significant impact on the work productivity. In this kind of task, the work productivity loss is not only seen from time loss but also due to functional incapacity of the workers. The workers are present at work but functionally limited due to work-related musculoskeletal disorders (WMSDs). There are various studies which have reported on the effects of WMSDs on the work productivity, but few attempts have been made to investigate the relationship. This study aims to develop a conceptual model of work productivity associated with WMSDs as an aid to identify the relationship between the risks of WMSDs and the work productivity. The knowledge on the relationship is important to reduce the risk of WMSDs and at the same time can optimize the work productivity. A conceptual model of work productivity associated with WMSDs in the industrial repetitive task was developed based on the review on the existing models and theories. The factors involved in the model were discussed. The factors involved were work-related physical risk factors, muscle fatigue, work-related musculoskeletal disorders and work productivity.

Abstract Background Work-related musculoskeletal disorders (WMSDs) affect a significant percentage of the neurosurgical workforce. The aim of the current questionnaire-based study was to examine the prevalence of WMSDs amongst neurosurgeons, identify risk factors, and study the views of neurosurgeons regarding ergonomics. Methods From June to August 2020, members of the “European Association of Neurosurgical Societies,” the “Neurosurgery Research Listserv,” and the “Latin American Federation of Neurosurgical Societies” were asked to complete an electronic questionnaire on the topics of WMSDs and ergonomics. Results A total of 409 neurosurgeons responded to the survey, with a 4.7 male to female ratio. Most of the surgeons worked in Europe (76.9%) in academic public hospitals. The vast majority of the participants (87.9%) had experienced WMSDs, mainly affecting the shoulder, neck, and back muscles. The most common operations performed by the participants were “Craniotomy for convexity/intrinsic tumors” (24.1%) and “Open lumbar basic spine” (24.1%). Neurosurgeons agreed that ergonomics is an underexposed area in the neurosurgical field (84.8%) and that more resources should be spend (87.3%) and training curricula changes should be made (78.3%) in order to alleviate the burden of WMSDs on neurosurgeons. Univariate analysis did not reveal any associations between the development of WMSDs and age, gender, tenure, average duration of operation, operating time per week, type of operation, and surgical approach. Conclusions The problem of WMSDs ought to be more closely addressed and managed by the neurosurgical community. More studies ought to be designed to investigate specific ergonomic parameters in order to formulate practice recommendations.

Background Work-related musculoskeletal disorders (WMSDs) have a significant impact on physical therapists, but few studies have addressed the issue. Research is needed to determine the scope of the problem and the effects of specific risk factors. Objectives The objectives of this study were: (1) to determine the 1-year incidence rate of WMSDs in physical therapists and (2) to determine the effects of specific risk factors. Design This was a prospective cohort study with 1-year follow-up. Methods Subjects were randomly selected American Physical Therapy Association members (N=882). Exposure assessment included demographic data, physical risk factors, job strain, and specific physical therapy tasks. The primary outcome was WMSDs, with a severity rating of at least 4/10 and present at least once a month or lasting longer than a week. Results The response rate to the baseline questionnaire was 67%. Ninety-three percent of the subjects who responded to the baseline questionnaire responded to the follow-up questionnaire. The 1-year incidence rate of WMSDs was 20.7%. Factors that increased the risk for WMSDs included patient transfers, patient repositioning, bent or twisted postures, joint mobilization, soft tissue work, and job strain. Limitations The primary limitation of this study was the number of therapists who had a change in their job situation during the follow-up year. Conclusions Work-related musculoskeletal disorders are prevalent in physical therapists. Physical therapy exposures, patient handling, and manual therapy, in particular, increase the risk for WMSDs.

A preshift stretching program was implemented to evaluate its effectiveness in preventing work-related musculoskeletal disorders (WMSD). Workers in a Midwestern factory were assessed for WMSDs before and after the new 8-min stretching program was implemented. Aggregate WMSD data were evaluated and sick days used from the start of the new program were compared with the same 60-day period the previous year. Potential cost savings were also assessed. The researchers found a significant decline in injury rates and time-off requests. Cost savings were noted for both the employer and employees. Additional studies with more workers, as well as longitudinal designs are recommended to verify the findings in this program evaluation study.

Objectives: The most common work-related diseases are musculoskeletal system disease. This study aims to determine the prevalence of work-related musculoskeletal disorders (WMSDs) in a high-hazard factory and to determine sociodemographic, occupational, and ergonomic risks. Methods: The research is cross-sectional and was conducted in a high-hazard factory, in Hatay, in 2017. The research population was all factory employees (N=190), and it was aimed to reach the whole population. Of the (97.3%), 185 employees participated in the study. Anthropometric measurements, the Cornell Musculoskeletal Discomfort Scale, the observation-based Rapid Upper Limb Assessment (RULA) Ergonomic Risk Analysis Scale, and a questionnaire developed by the researchers are used for data collection. In the statistical analyses p&lt;0,05was accepted as significant. Results According to the Cornell Scale, the frequency of WMSDs was 58.9%. The most common WMSDs were in the lumbar region (34.1%). According to the RULA Scale, 31.9% of the employees had 3rd and 4th-degree ergonomic risk. There were linear relationships between the Cornell Waist Score and each of the three RULA scores (p&lt;0.001). The risk factors for WMSDs in the lumbar region were the presence of chronic disease (OR=5.35), hand tool use (OR=2.63), not having had a work accident (OR=0.04) and RULA scores (OR=1.61), Conclusion: Approximately one-third of the high-hazard factory employees had a high ergonomic risk. WMSDs existed in more than half of the employees. As the ergonomic risk increases, WMSDs increase.

Abstract Objectives Varied work-related musculoskeletal disorders (WMSDs) claim rates were found between companies even when they were in the same sectors with similar sizes. This study aimed to (i) identify common risk factors for back, shoulder, hand/wrist, and knee WMSDs among manufacturing jobs, and (ii) characterize the biomechanical exposures in jobs and work organizational practices between high and low WMSD claim rate companies so that more focused, industry-specific intervention strategies may be developed. Methods Using historical workers’ compensation data, manufacturing companies were divided into two paired groups (low and high in the lower 25%ile and higher 75%ile, respectively). On-site job evaluations were conducted in 16 companies to determine job biomechanical risk levels. Management and workers’ representatives in 32 paired companies were interviewed to identify possible differences between management strategies and management/worker relationships. A total of 39 injured workers were also interviewed to gather information of self-reported injury causes and suggested preventive measures. Results Analyses of 432 job evaluations showed that more jobs had higher risk levels of prolonged standing and heavy lifting in the high back WMSD claim rate companies than the low claim rate ones. No high biomechanical risk factors were found to be associated with jobs in high shoulder claim rate companies. High repetition, pinch force, and Strain Index were associated with high hand/wrist WMSD claim rate companies. High work pace and job stress were common among high knee WMSD claim rate companies. There were no statistically significant differences for the organizational factors between high and low WMSD claim rate companies. Heavy lifting, fast work pace, high hand/wrist repetition, high hand force, and awkward shoulder postures were identified as major contributing factors by the injured workers. Conclusions High WMSD claim rate companies appeared to have more high biomechanical exposure jobs than low WMSD claim rate companies. Available job evaluation methods for the low back and hand/wrists are satisfactory in quantifying job risk levels in the manufacturing industry. Research into more sensitive job evaluation methods for the shoulder and knee are needed.

Physiotherapists are primary health care Professionals who diagnose and treat individuals of all ages, who have medical problems or other health related conditions, illness, or injuries that limit their abilities to move and perform the daily functional activities. Our aim was to review current knowledge associated with prevalence, risk factors, and preventive strategies of WMSDs among physiotherapist according to their work of specialization. Google Scholar and PubMed were searched for terms relating to WMSDs in Physiotherapists of various specialization from inception to 2021. There are many physiotherapy specialties including musculoskeletal, pediatrics, neurological, cardio- respiratory, rehabilitation, sports etc. and each one has its unique purpose and set of responsibilities. According to area of specialization in physiotherapy, occurrence of WMSDs at different body part may vary. Therefore, implementing preventive strategies for WMSDs in early stage of a physiotherapist’s career according specialization is needed.

Full textAbstract:
This research concerns the workplace design methodology, involving digital human models, that prevents work-related musculoskeletal disorders (WMSDs). We propose an approach that, in conjunction with one of the classic WMSD risk assessment methods, allows one to simplify simulations in a three-dimensional digital environment. Two real-life workstations from a manufacturing industry were modelled in a 3D Studio Max environment by means of an Anthropos ErgoMax system. A number of simulations show that, for the examined cases, classic boundary mannequins’ approaches can be replaced by using 50th percentile of a population individual, with a minimal impact on the WMSD risk. Although, the finding might not be suitable in all situations, it should be considered, especially where compromise solutions are being sought due to other criteria.

Musculoskeletal disorders (MSDs) represent a significant occupational problem among health care professionals; however, data on prevalence of work-related musculoskeletal disorders (WMSDs) are limited in our country for referencing. A descriptive cross sectional study was conducted during January to December 2016 among 160 health care professionals (doctors, nurses) working in a tertiary care hospital in Dhaka city. The aim of the study was to determine the prevalence, distribution and to find out the multiple risk factors that contribute to the development of WMSDs among the sample population. Data were collected with semi structured questionnaire based on a validated research instrument Standardized Nordic Questionnaire (SNQ) which records the prevalence of MSDs in terms of musculoskeletal symptoms (ache, pain, discomfort) in the preceding 12 months. The statistical analysis was done by using the SPSS software 21 version. The study result revealed that out of 160 (100.0%) health care professionals 109 (68.1%) had musculoskeletal pain or discomfort in the last 12 months and 51 (31.9%) had not, and it was also found that 57 (61.3%) doctors and 52 (77.6%) nurses had musculoskeletal pain or discomfort in the last 12 months and the prevalence of work-related musculoskeletal disorders in different body region in the last 12 months, where more than 1 site involvement 46 (42.2%) followed by neck 19 (17.4%), shoulder 15 (13.8%), lower back 13 (11.9%), hips 8 (7.3%), hand/fingers 5 (4.6%). About the self reported risk factors among the health care professionals for WMSDs were found working the same position for long periods 48 (29.8%),followed by treating excessive number of patients in a day 47 (29.1%), inadequate training on injury prevention 25 (15.9%), working awkward or cramped position18(11.6%).There were no statistically significant association found in age and years of experience of the health care professionals with the WMSDs (p value .281, .083 respectively), but significant association found in sex and occupation of the health care professionals with WMSDs (p value .045, .031 respectively). As because a high proportion of health care professionals had WMSDs and they are on the risk for development of WMSDs, it can be recommended that education programmes on prevention and coping strategies for musculoskeletal disorders be made mandatory for health care professionals in order to reduce the rate of WMSDs among them and to promote efficiency in patient care.Update Dent.

Full textAbstract:
BACKGROUND: Previous studies have observed that psychosocial factors are associated with an increase in work-related musculoskeletal disorders (WMSDs) in European countries. However, the influence of psychosocial factors on the WMSD symptoms has not been studied in detail. Additionally, working conditions differ between developing and developed countries. OBJECTIVE: In this study, the influence of psychosocial factors on WMSD symptoms among men and women in the footwear industry in northeastern Brazil is investigated. METHODS: A questionnaire survey was conducted to evaluate workers’ perceptions of psychosocial factors and WMSD symptoms. The influence of psychosocial factors on WMSD symptom trends was observed through ordinal logistic regression models. RESULTS: It was found that different psychosocial factors are related to WMSD symptom intensification. Factors such as “job insecurity” and “low social support,” which are not associated with the worsening of WMSD symptoms in developed countries, showed a noticeable influence in the sample analyzed. CONCLUSION: These findings may be associated with differences in working conditions and economic problems in developing countries, suggesting that some psychosocial factors have a different effect on workers’ perceptions in developing countries.

This study surveyed 114 Taiwanese and 57 Thai workers in a tape manufacturing factory in Taiwan and evaluated their symptoms of work-related musculoskeletal disorder (WMSD) and associated risk factors by using the revised Nordic Musculoskeletal Questionnaire. Task-appropriate biomechanical and body load assessment tools were also employed to examine biomechanical and body load during four specified daily tasks. The results indicated that the prevalence of discomfort symptoms in any body part within one year was 81.6% for the Taiwanese workers and 72.3% for the Thai workers. The body part in which the Taiwanese workers most frequently experienced discomfort was the shoulders (57.0%), followed by the lower back (47.4%), the neck (43.9%), and the knees (36.8%); where the Thai workers most frequently experienced discomfort was the hands or wrists (42.1%), followed by the shoulders (36.8%) and the buttocks or thighs (31.6%). These locations of discomfort were associated with task characteristics. Heavy-material handling (>20 kg) more than 20 times per day was the most significant risk factor for WMSDs for both groups, and this task must thus be urgently improved. We also suggest that providing wrist braces for Thai workers may assist in alleviating their hand and wrist discomfort. The biomechanical assessment results indicated that the compression forces acting on the workers’ lower backs exceeded the Action Limit standard; administrative controls must thus be instituted for two heavy-material handling tasks. In the factory, some tasks and workers’ movements when completing these tasks must be assessed and improved immediately by using appropriate tools. Although the Thai workers were engaged in more physically demanding tasks, their WMSDs were milder than those of the Taiwanese workers. The results of the study can serve as references for the prevention and reduction of WMSDs in local and foreign workers in similar industries.

Background: Rehabilitation clinicians have a high risk of occupational injury. Work-related musculoskeletal disorders (WMSDs) are one of the most frequent injuries for rehabilitation clinicians due to repeated heavy lifting and other forceful tasks. The primary objective of this study was to identify factors that caused or contributed to WMSDs for clinicians specifically working in rehabilitation settings (e.g., acute care, inpatient rehabilitation, long-term care, outpatient therapy). Methods: An, in person, proctored questionnaire was conducted of physical therapists (PTs), occupational therapists (OTs) and therapy assistants working at a rural community hospital. Information on general workload, work-related pain or discomfort, patient handling, and clinical experience were gathered using both a scripted interview questionnaire and a semi-scripted post-interview discussion. The questionnaire was analyzed using both descriptive and inferential statistical methods to determine the 1-year prevalence of WMSDs and factors associated with WMSDs and use of safe patient handling techniques. Results: Respondents (n=27) included 18 PTs, 6 OTs and 3 therapy assistants. On average, rehabilitation clinicians spent over eight hours per day delivering “hands-on” care to patients. During a typical workday, therapists spent more than 20% performing heavy lifting, physically fatiguing tasks, or were in a static or awkward posture. Bending or twisting, repetitive tasks, and kneeling or squatting were each performed 30% or more of a typical workday, especially bending or twisting (38%). More than half (63%) suffered musculoskeletal pain/discomfort during the past year. Inadequate lifting devices were reported to be available in the working environment. A negative association was observed between the availability of multiple lifting devices and WMSDS (p-values<0.05). Less than a third of clinicians (31.5%) reported complete confidence to use mechanical lifting devices during rehabilitation activities. Conclusion: Rehabilitation clinicians are at higher risk for WMSDs due to patient handling tasks. More ongoing training must be provided to ensure clinicians have confidence to use the technologies available for rehabilitation tasks. However, additional research is still needed to understand the causal factors of WMSDs related to patient handling, particularly for rural care settings that lack access to technology and adequate staffing.

A survey of Washington State employers was conducted in 1998 to ascertain employer perceptions about the presence of work-related musculoskeletal disorders, risk factors, measures taken to address these problems, their benefits and where employers turned for help on these issues. Almost 5,000 employers responded to the survey (75% response rate). About one-third reported experiencing musculoskeletal disorders in the workplace, 56% reported employees exposed to at least one risk factor more than 2 hours per day. Of those who reported taking steps to prevent WMSDs, most were successful in reducing WMSD incidence or severity and experienced collateral benefits.
