Backgroundand Objectives: Disorders caused due to working patterns or work related stresses are called occupa-tional disorders.Work related neck disorders are common problems in office workers,especially among those who are intensive computer users.Banking occupation requires a lot of stereotyped movements of the arms, hands and fin-gers,and repetitive occupational tasks with short cycle times have become more and more frequent in modern tech-nology as seen in this type of occupation with many of them associated with increased rates of chronic neck pain. Work place rehabilitation is necessary for work related to chronic neck pain in bankers.The objective of the study was to evaluate the effectiveness of the Work hardening program along with Conservative treatment versus Conservative treatment alone in bankers having Chronic neck pain. Methods:60 bankers having Chronic neck pain were randomly allocated in two groups.Group A received Conservative treatment alone and Group B received a Work hardening program along with Conservative treatment.The outcome was assessed in terms of Neck Disability Scale (NDI) scores and Numeric Pain rating Scale (NPRS) scores pre interven-tion and post intervention. Results:Both the interventions of conservative treatment and conservative treatment with a work hardening pro-gram were individually effective.But,the subjects treated with a conservative with work hardening program was sig-nificantly effective than conservative alone. Interpretation and Conclusion:The present study concludes that both treatment protocols were effective in reduc-ing Chronic neck pain.Further it was also noticed that Group B was more effective in improving neck disability and in reducing pain than Group A.Thus applying for the treatment protocol Work hardening program along with Conserva-tive treatment was better than Conservative treatment applied alone.

The aim of the present study was to examine the prevalence of work-related musculoskeletal complaints and potential risk factors among Romanian surgeons. Ninety-five surgeons of different specialties (62.11% males) completed a questionnaire about work-related musculoskeletal complaints (WMSCs). Ninety-one surgeons (95.78%) experienced WMSCs at least in one body part in the last year. Most surgeons reported pain in four body parts (33.68%). The most common WMSCs were reported on the lower back (74.73%), followed by complaints in the neck region (55.79%), shoulder and upper back (46.32%), knee (31.58%), wrist–hand (16.84%), elbow (14.74%), hip (11.58%) and ankle–foot (4.21%). Surgeons rated their pain more severe on upper back, lower back and knees. A higher percentage of male surgeons reported upper back pain (χ2(1) = 5.818, p = 0.015). Significant age differences were found between the reported pain sites (F8,278 = 2.666, p = 0.008); the surgeons reporting wrist–hand pain were younger than those reporting neck, shoulders, elbows, dorsal and lumbar pain. Surgeons with significantly less experience in years reported significantly more WMSCs in wrist–hand, hip and ankle–foot regions compared with those more experienced (p < 0.05). Surgeons are at high risk of developing work-related musculoskeletal complaints, which affects both their professional and personal life. Further studies are needed to identify all risk factors and ergonomic strategies to reduce the prevalence and the negative impact of WMSCs.

Prevalence of neck-shoulder pain among sewing machine operators is well known. It may be due to the nature and incorrect posture used by sewing machine operators while performing sewing work. However, up till now there is no empirical evidence that can be used to relate the risk factors that would results towards the development of neck and shoulder pain among sewing machine operators. The main objective of this study is to identify and investigate the risk factors that result in neck and shoulder pain among Malaysian sewing machine operators. Twenty female sewing machine operators took part in answering a survey questionnaire to investigate the prevalence of neck and shoulder pain among sewing machine operators. The survey questionnaire was divided into five sections: socio-demographic, work background, workload information, physical exposures and physical musculoskeletal symptoms experienced by workers. Having done that, sewing machine operators who have been screened with neck and/or shoulder pain was evaluated with Rapid Upper Limb Assessment (RULA) to determine the level of workplace risk factors. Subjects without neck and/or shoulder pain were excluded. Results of the study shows that all sewing operators were expose to risk of prolonged sitting, repetitive task and working at high speed. Ninety five percent of sewing machine operators had experienced neck and/or shoulder pain and 80% of them were exposed to high work risk factors that require them to undergo further investigation. Shoulder pain was found to be strongly correlated with high work risk factor among sewing machine operators (p<0.05). In conclusion, occurrence of shoulder pain among sewing operators is due to posture and nature of sewing work.

Full textAbstract:
The emergence of the global pandemic novel coronavirus (COVID-19) has greatly changed the ways on how people live their lives from the usual and has significantly challenged every nation to deal with the economic struggle. Work-related musculoskeletal disorders (WMSDs) are musculoskeletal system abnormalities that are predominantly brought on by the execution of work tasks and the immediate work environment (Govaerts et al., 2021). The aim of this study was to determine the prevalence of work-related musculoskeletal pain in various anatomical areas and its association with individual, work area and ergonomic, and work spending hours among work-from-home medical billers. The questionnaire that was designed by the author is a web-based, self-reporting survey that was sent to all respondents by email and uses the convenience sampling method. The study has a response rate of 54.48% which was participated by thirty-four (34) respondents out of the sixty-four (64) work from home (WFH) employees in a medical billing company. The respondents are composed of 10 males (29.4%) and 24 females (70.6%) between the ages of 18 and 45 years, having both genders with a mean age of 31 who had been working from home for the last three months to one year before they joined the study. The results found that 72.6% of the participants experienced work-related musculoskeletal pain (WRMSP). It also showed that the highest percentage of pain experienced was the low back area, followed by the neck and shoulder and lastly by the upper back suggesting that these are the most prevalent sites. The data identified that 47% of the respondents that use a standard chair without armrest (40%) and no foot rest (68%) are prevalent with low back and neck pain areas. The results suggested that 82% of the participants experienced low back pain as the primary work related musculoskeletal pain in the last 12 months and this results to poor workplace ergonomics, long working hours in front of the computers and minimal to nonphysical activities and sedentary lifestyles.

Background: The number of individuals with work-related musculoskeletal disorders is increasing in Poland. Aim of the study: The aim of this study was to analyze and evaluate pain symptoms among upholsterers and to compare these ailments with a group of employees who do not perform physical work, as well as to examine the associations between pain intensity and frequency with age, length of employment, and somatic characteristics in both research groups.Materials and methods: Ninety-four men were examined, including 50 upholsterers and 44 non-physical workers, who were the control group. Pain location was assessed using the Nordic Musculoskeletal Questionnaire, pain intensity lower back was measured using a Visual Analog Scale (VAS), and the frequency of lower back pain was determined using the Jackson-Moskowitz Scale. Participants also provided information regarding their age, length of employment, and education. Body mass and height were measured.Results: Among the study participants, 94% of the upholsterers and 73% of the control group experienced pain in at least one area of the body. The largest percentage of the study participants from both groups reported pain in the lower back. Upholsterers experienced pain in their elbow joints and hands/wrists significantly more often than control group. The control group experienced pain in the upper back, neck, and hip joints significantly more often than upholsters. Significant positive correlations were found between age, length of employment, and the results of the VAS and Jackson-Moskowitz Scale in both groups.Conclusions: The locations of pain complaints in the group of upholsterers and in the group of employees who do not perform physical work differ. In both groups, lower back pain predominates. Working as an upholsterer promotes pain in the elbow joints, and wrists/hands. Performing mental and mixed work is associated with neck, upper back and hips/thighs pain. Future studies should aim to assess the prevalence and analyze the risk factors for work-related musculoskeletal disorders.

ABSTRACT Introduction Dentists are at a very high risk of developing work-related musculoskeletal pain. The present study aimed at studying the prevalence of musculoskeletal pain among different dental specialists in the United Arab Emirates (UAE), and correlating the region of pain with the type of clinical work done by the specialists. Materials and methods A sample of more than 100 dentists was chosen randomly from different emirates in UAE. An interview questionnaire was administered regarding the number of years of experience and the presence, region, duration, and type of musculoskeletal pain they experienced. Results Musculoskeletal pain is experienced by 83.3% of periodontists, 80% of conservative dentists, 77.8% of endodontists, 72.7% of orthodontists, 70% of oral surgeons, 63.6% of prosthodontists, 63% of general dental practitioners, and 50% of pedodontists. The results have also indicated that the region of experienced musculoskeletal pain does vary according to the specialty. From those dentists who experience work-related musculoskeletal pain, 80% of conservative dentists experience pain in neck and shoulders, 66.7% of periodontists, and 54.5% of orthodontists experience pain in the lower back region. More than 50% of endodontists experience pain in the neck and shoulders regions, and 39% of general dental practitioners who experience pain in the neck region. Conclusion Preventive measures need to be taken to decrease the risk of dentists and dental specialists developing workrelated musculoskeletal pain. Clinical significance The prevalence and distribution of musculoskeletal disorders (MSDs) among registered general dental practitioners and dental specialists in UAE was not clearly documented. The study results indicated that the region that experienced musculoskeletal pain does vary according to the specialty.

Full textAbstract:
Computer technology has advanced rapidly in the past few decades and computers have become a very important and powerful tool in our everyday lives. Prolonged computer use by office workers has been reported to result in an increased risk of developing Work-related Neck and Upper Limb Disorders (WRNULD) (Bernard et al.. 1994: Faucett & Rempel. 1994: Tittiranonda et al.. 1999). The occupational risk factors associated with prolonged computer use include static posture and the speed and force of keyboard operation. Past studies have examined different aspects of these risk factors through measuring muscle electrical activity (EMG), kinematics and keyboard forces. However, most of these studies have been conducted on healthy painfree subjects and even the few Case-Control studies have not clearly established any direct relationships between the risk factors and WRNULD. The present research project consisted of a series of three studies aimed at investigating whether there were intrinsic differences among different individuals in response to different physical stressors. These intrinsic differences may have important implications to help explain why some individuals would develop WRNULD while others do not. The individuals' responses to the demands of three physical stressors: static posture, speed and force of keyboard operation were assessed. The internal exposure measures of kinematics, EMG, keyboard dynamics and subjective discomforts were used to evaluate the inter-individual differences. Study I was a field investigation comparing the neck-shoulder kinematics between symptomatic ("Case", n=8) and asymptomatic ("Control", n=8) office workers. Results showed trends for consistently greater head tilt and neck flexion angles, and greater ranges of movements in the Case Group than the Control Group.The Case Group also exhibited a trend for increased acromion protraction compared to the Control Group. The Case Group also reported significantly greater discomfort scores compared to the Control Group. Neither the discomforts nor the kinematics displayed any significant changes over a working day. Study 2 was a laboratory study comparing the responses of Case and Control Groups in terms of EMG, kinematics and subjective discomforts, while a standardised computer task was performed continuously for one hour. The responses of Case (n=23) and Control (n=20) Groups were compared to examine the effects of static posture. The results showed similar trends to those in Study I, with increased neck flexion mean angles and ranges of movements in the Case Group compared to the Control Group. In terms of EMG results, there were trends for EMG amplitude differences in the right upper trapezius (UT) and cervical erector spinae (CES) muscles between Case and Control Groups. These trends became statistically significant when the Case subjects were sub-divided into the High (n=15) and Low (n=8) Groups based on their mean discomfort scores. Study 3 was also a laboratory study to compare the Case (n=21) and Control (n=20) Groups when they were challenged by the physical stressors of speed and force of keyboard operation. In this study, each subject's EMG and discomforts were examined in three typing conditions of normal speed and force, increased typing speed and increased typing force. The Case Group showed trends for higher increases in both UT and CES muscle activities than the Control Group, and when divided into the High-Low Groups, the High Group (n=8) showed trends for much higher muscle activities in all three conditions.Beside muscle activity changes, the High Group subjects also demonstrated a trend for much higher within-subject Speed and Force Variabilities in their keystroke performance, compared to the Low Group and the Control Group. This result implied that the High Group subjects had a more erratic motor control of the keystroke actions. Based on these results, conceptual models were developed to describe the relationships among the physical stressors, internal exposure responses and discomforts. The Altered Motor Control Model refers to the programmed changes in motor control strategies involving muscle recruitment and joint movement patterns, and these changes were closely related to the subjects' musculoskeletal discomforts. The Heightened Sensitivity Model describes the higher sensitivity levels of individuals with more severe discomforts, in response to the demands of physical stressors. These models are closely related and heightened sensitivity may be an 'effect-modifier" of the motor control mechanisms and the perception of discomforts or pains within the individual. In conclusion, the present research has identified important differences between individuals on the basis of their motor control strategies which may contribute to the development of WRNULD. While the present research has mainly examined the individual responses to three physical stressors, it is possible that the models developed may be applicable to other physical stressors. These findings may also have important implications for future ergonomic research, emphasising the need to address interindividual differences in ergonomic interventions to workers. Further research should be directed towards better understanding of these intrinsic individual differences in both physical and non-physical factors that contribute to the development of WRNULD.

Full textAbstract:
Prolonged computer work is associated with high rates of neck and shoulder pain symptoms, and as computers have become increasingly more common, it is becoming critical that we develop sustainable interventions targeting this issue. Static muscle contractions for prolonged periods often occur in the neck/shoulder during computer work and may underlie muscle pain development in spite of rather low relative muscle load levels. Causal mechanisms may include a stereotypical recruitment of low threshold motor units (activating type I muscle fibers), characterized by a lack of temporal as well as spatial variation in motor unit recruitment. Based on this theory, although studies have postulated that individuals with chronic neck-shoulder pain will show less variation in muscle activity compared to healthy individuals when engaged in repetitive/monotonous work, this has seldom been verified in empirical studies of actual computer work.
Studies have rarely addressed temporal patterns in muscle activation, even though there is a consensus that temporal activation patterns are important for understanding fatigue and maybe even risks of subsequent musculoskeletal disorders. This study applied exposure variation analysis (EVA) to study differences in temporal patterns of trapezius muscle activity as individuals with and without pain performed computer work. The aims of this study were to: Assess the reliability of EVA to measure variation in trapezius muscle activity in healthy individuals during the performance of computer work; Determine the extent to which healthy subjects differ from those with chronic pain in trapezius muscle activity patterns during computer work, measured using EVA.
Thirteen touch-typing, right-handed participants were recruited in this study (8 healthy; 5 chronic pain). The participants were asked to complete three 10-minute computer tasks (TYPE, CLICK and FORM) in two pacing conditions (self-paced, control-paced), with the healthy group completing two sessions and the pain group completing one. Activation of the upper trapezius muscle was measured using surface electromyography (EMG). EMG data were organized into 5x5 EVA matrices with five amplitude classes (0-6.67, 6.67-20, 20-46.67, 46.67-100, >100% Reference Voluntary Exertion) and five duration classes (0-
1, 1-3, 3-7, 7-15, >15 seconds). EVA marginal distributions (along both amplitude and duration classes) for each EVA class, as well as summary measures (mean and SD) of the marginal sums along each axis were computed. Finally, “resultant” mean and SD across all EVA cells were computed. The reliability in
EVA indices was estimated using intra-class correlation coefficients (ICC), coefficient of variation (CV) and standard error of measurement (SEM), computed from repeated measurements of healthy individuals (aim 1), and EVA indices were compared between groups (aim 2).
Reliability of EVA amplitude marginal sums ranged from moderate to high in the self-paced condition and low to moderate in the control-paced condition. The duration marginal sums were moderate in the self-paced condition and moderate to high in the control-paced condition. The summary measures (means and
SDs) were moderate to high in both the self-paced and control-paced condition. Group comparisons revealed that individuals with chronic pain spent longer durations of work time in higher EVA duration categories, exhibited larger means along the amplitude, duration and in the resultant, and higher EVA SD
in the amplitude and duration axes as compared to the healthy group.
To our knowledge, this is the first study to report on the reliability of EVA applied specifically to computer work. Furthermore, EVA was used to assess differences in muscle activation patterns as individuals with and without chronic pain engaged in computer work. Individuals in the pain group seemed to exhibit prolonged sustained activation of the trapezius muscle to a significantly greater extent than controls, even though they did not experience pain during the performance of the computer tasks (as obtained through self-reports). Thus, these altered muscle recruitment patterns observed in the pain subjects, even in the absence of task-based pain/discomfort, are suggestive of chronic motor control changes occurring in adaptation to pain, and may have implications for the etiology of neck and upper-limb musculoskeletal disorders.<br>Master of Science<br>This study aims to assess the reliability of exposure variation analysis (EVA) to measure variation in trapezius muscle activity in healthy individuals during the performance of computer work, and to determine the extent to which healthy subjects differ from those with chronic pain in trapezius muscle activity patterns during computer work, measured using EVA. Muscle activation was recorded for eight healthy individual and five suffering from chronic neck-shoulder pain. The data were then categorized into amplitude and continuous time categories, and summary measures of resulting distributions were calculated. These measures were used to assess the reliability of participant responses to computer work of healthy individuals, as well as quantify differences between those with and without chronic pain. We found that individuals with pain activated their neck-shoulder muscles for longer continuous durations than healthy individuals, thus showing an inability to relax their muscles when performing work.

Full textAbstract:
Clinical and somatosensory characteristics of patients with nerve-related neck-arm pain were investigated. This research demonstrated that clinical classification systems are useful in differentiating presentations of nerve-related neck-arm pain and in identifying neuropathic pain components in these cohorts. Distinct clinical and somatosensory profiles were documented for patients with cervical radiculopathy and patients with non-specific neck-arm pain, suggesting differences in the underlying pain types and pain mechanisms. Findings may assist clinicians in better targeting patient management.

Full textAbstract:
Introduction: Musculoskeletal pain is a common problem in the working population. In Sweden, 40% of women and 30% of men report suffering from neck and shoulder pain weekly. The underlying cause for neck pain is often not known and the treatment is commonly guided by the individual’s symptoms. However, there is a lack of knowledge on how to receive the best effect based on the individual’s symptoms and functional limitations, and therefore this has been scarcely evaluated in research. Furthermore, the impact of work exposure and stress on long-term treatment for persons with neck pain is not clear. Aims: To develop (paper 1) and to evaluate a decision model for tailored treatment in women with neck pain (paper 2). Moreover, to determine if risk factors at work and stress influence intermediate and long-term treatment results (paper 3). Further, to investigate if changes in self-reported pain and disabilities are associated with changes of physical test outcomes of the neck and shoulder region after treatment (paper 4). Methods: In an RCT, 120 working women with non-specific neck pain were randomized to three different groups – tailored treatment (TT), non-tailored treatment (NTT) or treatment-as-usual (TAU) for an 11 weeks intervention with short-term, intermediate-term and long-term follow-ups. The TT group was guided by a decision model with cut-off levels to indicate impairments. The NTT group received two established treatment components randomly from those not indicated, and TAU group did not receive any treatment within the study. The RCT primary outcomes were self-reported neck pain and neck disability. A linear mixed model was used for analysing the effects. One week after the end of intervention work exposure and stress were assessed at a work-place visit and associations to treatment results were tested for, and mixed models were used to estimate longitudinal associations. Associations between self-reported neck problems and physical outcomes were estimated with univariate and multiple regressions analysis. Results: No differences between TT and NTT were revealed for neck pain and disability. In comparison to TAU, the TT and NTT groups both showed improvements at short-term follow-up, but not at intermediate and long-term follow-up. High stress level and low self-estimated control at work were associated with more pain and disability at the intermediate and long-term follow-ups. After intervention and at the intermediate-term follow-up, reduced neck pain, disability and frequency of symptoms were associated with increased peak speed of head rotation and cervical range of motion. Conclusion: Tailored treatment according to the decision model was not superior to the non-tailored treatment in women with non-specific neck pain. One explanation for this can be the weak relationships found between neck pain and disability and physical test outcomes. Further, perceived stress and psychosocial work exposure were associated with self-reported neck problems and should be taken into account to optimize the effects in neck pain rehabilitation.<br>Bakgrund: Nack- och skulder-smärta är ett vanligt tillstånd som förekommer över hela världen. I Sverige skattar 30-40% besvär från nacke och skuldror mätt under en veckas tid. Generellt rapporterar kvinnor mer nack- och skulder-besvär än män. I avhandlingen är det ospecifik nacksmärta som har studerats, det inkluderar inte t.ex. Whiplash-skador, diskbråck eller andra mer specifika diagnoser. Den bakomliggande orsaken till ospecifik nacksmärta är, precis som beteckningen antyder, ofta inte känd och individens symptom och funktion är istället vägledande i undersökning och behandling samt utvärdering av behandling. Studier har visat att i jämförelse med friska har individer med ospecifika nackbesvär ofta sämre muskulär nackstyrka, minskad rörlighet i nacken och är något långsammare vid test av huvudrörelser. Behandlingen riktar sig ofta mot något av dessa fynd med bl.a. styrketräning av nackmuskler och/eller manuella tekniker för rörelseökning. Studier har dock visat att behandlingen endast ger måttliga resultat och att de positiva resultaten bara är kortvariga. I kliniken försöker man individanpassa behandlingen utifrån patientens behov men det finns väldigt lite forskning om detta utan studier utvärderar likadan behandling för hela grupper. Det saknas fortfarande kunskaper om hur man på bästa sätt individanpassar behandling så att den blir skräddarsydd utifrån individens symptom och funktion samt utvärderar detta. Syftet med avhandlingen var att undersöka om en intervention med skräddarsydd behandling (som också innehöll specifik aktiv träning) utifrån en beslutsmodell med fysiska tester och frågor om symtom är effektivt för att uppnå positiva effekter i självskattad smärta och funktion (artikel 1 och 2). Den skräddarsydda behandlingen jämfördes mot en grupp som fick samma upplägg men inte skräddarsydd behandling. Vidare undersöktes om båda dessa behandlingsgrupper var effektivare än en grupp som inte fick någon behandling i studien. Dessutom undersöktes om påverkan från arbetsmiljön i form av fysisk och psykosocial belastning samt upplevd stress påverkade behandlingsresultaten efter interventionen (artikel 3). Slutligen undersöktes om de fysiska testerna och den självskattade smärtan, funktionen och symptomen hade koppling till varandra dels före interventionen och dels i termer av förändringar efter interventionen (artikel 4). Metod: I en randomiserad kontrollerad interventionsstudie (RCT) inkluderades 120 kvinnor i åldrarna 20-65, alla i arbete, och som hade ospecifika nackbesvär. De lottades till tre grupper, (1) skräddarsydd behandling (Tailore treatment, TT), (2) icke-skräddarsydd behandling (Non-tailored treatment, NTT) och (3) en kontrollgrupp (Treatment-as-usual, TAU) som inte fick någon behandling i studien men var fria att söka vård på egen hand. Kvinnorna i TT-gruppen fick behandlings-komponenter utifrån testresultaten i beslutsmodellen. Det kunde läggas till någon behandlingskomponent om det visade sig behövas utifrån individens behov i vardagen. Detta undersöktes genom en strukturerad intervju-teknik som kallas Problem Elicitation Technique (PET). Kvinnorna i NTT-gruppen fick två lottade behandlings-komponenter som inte matchade deras behov utifrån testerna i beslutsmodellen. För båda behandlings-grupperna var interventionen 11 veckor med inbokade behandlingstillfällen 2-3 gånger per vecka, samtliga tillfällen vägledda av fysioterapeut. Data för alla tre grupper samlades in innan interventionen samt 3, 9 och 15 månader efter start av interventionen. Gruppskillnaderna analyserades med en ”linear mixed model”. En vecka efter intervention gjordes ett arbetsplatsbesök hos individerna i alla tre grupper. En erfaren ergonom observerade individernas fysiska arbetsbelastning med ett ergonomiskt bedömningsinstrument, Quick Exposure Check (QEC), och individerna skattade också den psykosociala arbetsmiljön i ett frågeformulär, QPS Nordic, samt upplevd stress. För att undersöka om den fysiska och psykosociala arbetsbelastningen samt stress påverkade resultaten från interventionen analyserades data med linjär regression och mixed model. För att undersöka om de fysiska testerna och den självskattade smärtan, funktionen och symptomen hade något samband användes linjär regressionsanalys. Resultat: Att skräddarsy behandlingen utifrån den testade beslutsmodellen var inte effektivare än att inte skräddarsy. I jämförelse med kontrollgruppen självskattade båda behandlingsgrupperna mindre smärta, bättre funktion och mindre symptom efter interventionen. I de länge uppföljningarna (9 och 15 månader) var dock skillnaderna mellan grupperna inte längre signifikanta förutom att båda behandlingsgrupperna, till skillnad från kontrollgruppen, upplevde sig bättre än innan behandling. Det visade sig att upplevd hög stressnivå och låg kontroll på arbetet hade samband med mer självskattad nacksmärta, sämre funktion och lägre arbetsproduktivitet. De fysiska testerna och självskattade nackbesvär hade bara svaga samband. På baslinjenivå, innan interventionen, fanns det samband mellan hög nackstyrka och låg självskattad funktion och låg frekvens på symptomen, samt mellan att vara långsam i testet av snabba huvudrörelser och hög smärta. Efter interventionen hade individernas förändring i självskattad smärta fortfarande bara samband med snabba huvudrörelser. Förbättring i självskattad funktion och symptom hade samband till ökad hastighet i snabba huvudrörelser och ökat rörelseutslag nackrotation. Sammanfattning: För kvinnor i arbete med ospecifika nackbesvär var det inte mer effektivt att skräddarsy behandling/träning utifrån en beslutsmodell jämfört med att slumpmässigt välja ut behandlingskomponenter från samma behandlingsarsenal. En förklaring kan vara att det fanns endast låga samband mellan självskattad smärta och funktion och de fysiska testerna. Upplevd stress och kontroll i arbetet visade sig ha samband med självskattad smärta, funktion och arbetsproduktivitet och bör tas i beaktande i framtida interventioner för individer med nacksmärta.

The fundamentals of kinematics and dynamics of transport piston internal combustion engines made using different layout schemes are presented. Along with the traditional in-line, V-shaped, including oppositional, arrangement of cylinders, schemes with "staggered" arrangement of cylinders in the block at the displaced connecting rod necks of the crankshaft of the engine are considered. The kinematics of the coaxial crank mechanism is considered in detail. The questions of dynamics with reduction of calculated dependences of forces, moments, a choice of a rational order of work of cylinders in relation to the considered kinematic schemes are in detail stated. Considerable attention is paid to the unevenness of the crankshaft rotation speed and engine balancing. The loads on the main and connecting rod bearings of the crankshaft, the knowledge of which is necessary in determining the bearing capacity of bearing units, are also considered.

Full textAbstract:
Sure to be welcomed by the thousands suffering persistent pain, this volume explores what physicians often ignore—how psychological and social issues can influence health, illness, pain, and recovery. "Pain is everywhere and everyone is talking about it," says Dr. Hillel Finestone, M.D., a researcher and rehabilitation specialist whose work has been featured in publications as diverse as The Lancet, and USA Today. The key to understanding causes and solutions for many apparently mysterious, recurring aches, he explains, lies in understanding the mind-body relationship and the ""real meaning"" behind symptoms with no immediately obvious cause. Taking the reader into several diagnostic sessions to illustrate what he sees as a ""detective"" process to find the source of pain, Finestone explains how psychological and social issues can influence health and healing, for better or worse. Low back and neck pain, fibromyalgia and even work related pains are delved into.In addition to vignettes that illustrate the ideas discussed and show dramatic incidences of how healing the mind can also heal the body, Finestone uses unique and useful diagrams which explain how mind and body are physiologically connected and reactive to each other. In these pages, readers can follow Dr, Finestone through patient sessions and understand, step by step, how the ""pain detective"" works to help his patients—and perhaps his readers, too—find lasting relief.

Full textAbstract:
The aim of this study was to evaluate the prevalence of upper body quadrant pain among ultrasonographists and to evaluate the association between individual ergonomics, musculoskeletal disorders, and occurrence of neck pain. A hundred and ten Belgian and Dutch male and female hospital ultrasonographists were consecutively enrolled in the study. Data on work-related ergonomic and musculoskeletal disorders were collected with an electronic inquiry, including questions about ergonomics, symptoms and work related factors. Subjects with the screen on their left had significantly more neck pain. Depending on the work space, high-low tables increased the chance on developing neck pain. A screen on eye level caused less neck. Employees with a fixed working space were less susceptible to arm pain. The prevalence of arm pain was significantly higher on the vascular department compared to the radiology, urology and gynecology departments. In the prevention of upper limb pain in ultrasonographists, attention should be paid to the work environment in general, and to the more specific aspects of the ultrasound workstation layout. Primary ergonomic prevention could help the ultrasonographist to work painless during his medical tasks.

Full textAbstract:
Repetitive and monotonous work is often associated with neck pain, potentially resulting in sick leave and reduced productivity. Establishing appropriate muscle activity patterns, including duration and frequency of breaks that can prevent development of neck pain is important for providing workplace guidance. While several smaller studies of monotonous neck-loading work have indicated that such breaks can reduce the risk of neck pain, studies with a higher number of participants are necessary to confirm an association, and if so, to improve the precision of a possible association. The purpose of this protocol is to describe and discuss the background, methods and challenges of a study pooling several datasets with measurements of upper trapezius muscle activity during work and associated measurements of neck pain. Methods: Seven Scandinavian research institutes provided surface electromyographic (EMG) data of upper trapezius muscle activity recorded during working hours along with questionnaire data with information about neck pain and other health-related factors, from a total of 750 participants. The different data sets of the EMG data will be merged into a common format. Various questions on neck pain will be harmonized. Associations between EMG variables and neck pain will be examined with linear mixed model regressions controlled for various confounders. Discussion: Aiming to provide further insight into the possible association between trapezius muscle activity pattern and neck pain, this study protocol highlights the challenges that arise when creating a pooled data set. Solving these challenges may help to increase the knowledge about appropriate muscle activity patterns during work.

Full textAbstract:
Work-related chronic neck pain is a growing condition in the United States that accounts for 56% to 65% of all occupational disabling injuries [1]. Fifty-four percent of working adults suffer from chronic neck pain within any six-month period and 5% of working adults report that neck pain significantly inhibits daily activities [2]. These conditions have been linked to poor posture in the cervical spine and shoulder [3]. Poor cervical spine posture commonly includes simultaneous extension in the upper vertebrae (C1-C3) and flexion in lower vertebrae (C7-C4). This posture moves the head anterior to the torso and increases the load carried by the upper trapezius (UT) [4]. To maintain this posture, the UT is activated and elevates the scapula. Chronic activation of the UT has been correlated to chronic neck pain [5]. Although there is an apparent correlation between poor posture and neck pain, it is unclear whether neck pain causes poor posture or if poor posture causes neck pain.

Musculoskeletal disorders (MSD) are incredibly common and are often related to work load. For any occupational or public health intervention, injury prevention is preferred to injury treatment. Occupational health and injury prevention research has the potential to help mitigate MSD in the workplace. The aim of this study was to determine how the work demands of ski instructors may affect the health of their musculoskeletal system. Material and Methods A cross-sectional study involved the participation of 87 ski instructors (age = 34.61 ±10.67) in Bosnia and Herzegovina (ATUS in Bosnia and Herzegovina). Observed variables were the prevalence of MSD measured using a modified Nordic questionnaire about injuries during the previous ski season (neck, shoulders, elbows, wrist, upper back, lower back, one or both hips, one or both knees, and ankle). Means and standard deviations for each of the variables were calculated, and differences between genders were examined using an independent sample t-test. Results Prevalence of MSDs in ski instructors was most common in neck (13.8%), shoulders (12.6%), elbows (4.6%), wrist (9.2%), upper back (10.3%), lower back (46.0%), one or both hips (9.2%), one or both knees (29.9%), and ankle (9.2%). The results showed statistically significant differences in MSD between genders in the neck (p=.034); shoulders (p=.017); upper back (p=.027); one or both knees (p=.003) and in the ankle joint (p=.011).

Full textAbstract:
The enrichment of the garments industry in Bangladesh has given employment to millions of people, especially women. With cellular manufacturing, enhanced productivity accompanies increased musculoskeletal disorders risk (Shaheen A., Mohammad Z.R, 2014). Sewing operators working posture is a vital factor related to musculoskeletal symptoms (Dianat et al., 2015). However, there is limited research on the ergonomic needs evaluation among Bangladesh female sewing machine operators.Seven female sewing machine operators in a garment manufacturing unit in Dhaka, Bangladesh, were recruited for this pilot study. A combined survey sheet was developed to record demographic information and CMDQ questionnaires. The demographics included age, weight, height, marital status, and education level. CMDQ is a survey sheet to evaluate the rating of symptoms in specific body parts (neck, shoulder, arm, upper back, lower back, leg) by multiplying the frequency, severity, and interference scores. Anthropometric measurement and sewing facilities (table and chair) dimension measurement were conducted. Subjects were interviewed about their subjective opinions on the ergonomic functions of sewing machine facilities.Participants were 31.6±8.8 years old, 56.4±8.4 kg, and 5.27±0.35ft. They are married, and their educational levels range from class 5 to 8. A typical daily work process of a female sewing machine operator in a garment manufacturing unit in Bangladesh is constantly sitting for more than 10 hours with a 1-hour lunch break. They hardly move around, only to pick up their work in the morning and submit their production to their supervisor at the end of the day. After a whole day of work, four people reported lower back pain, while three reported neck pain, 2 with leg pain, and 1 with arm pain. Lower back got the highest discomfort score (26.5), followed by neck (10), arm (7), and leg (3). The mismatch computations between body and facility dimensions showed that the current design of sewing facilities is unsuitable for female workers. The seat height is too low, and the hip width is too narrow for them. According to interviews, subjects complained about their current working chair without elbow rest which was quite uncomfortable for them to work. It could be one of the reasons that a worker is facing severe arm pain. Consistent with anthropometric measurement results, several subjects mentioned that the seat and desk height was inappropriate for them. They had to use a cushion on the seat to make them more comfortable.In conclusion, female sewing operators in Bangladesh's garment industry face a high risk of musculoskeletal disorders with mismatched facility dimensions and little consideration of their ergonomic design. A better understanding of their ergonomic needs involving sewing operations can potentially impact workers' quality of life and national productivity.

"Evaluation of electromagnetic hypersensitivity (EHS) of Business Process Outsourcing (BPO) employees under traditional and remote work environments." In AHFE 2023 Hawaii Edition.

Full textAbstract:
Following the success of remote work in the Business Process Outsourcing (BPO) industry during the Covid-19 pandemic, several organizations have considered choosing a permanent remote work policy for their employees over the traditional face-to-face setup. The primary determinants that dictate adopting a permanent working environment are often centered on cost-related considerations with little regard for the slow onset of occupational health hazards. Studies have identified various health hazards experienced by BPO personnel, including headaches, back pain, neck and shoulder discomfort, wrist and hand pain, eye strain, overweight, hearing loss, and digestion issues. Electromagnetic hypersensitivity (EHS) is a term used to describe such symptoms that manifest in response to exposure to electromagnetic field (EMF)-emitting devices. In the context of the Philippines, most are unaware of the potential implications of EMF exposure, hence it is worthwhile to closely investigate the EHS of BPO employees. This study aims to investigate the health-effects of EMF-emitting devices on BPO personnel in both traditional and remote work setups. The study used a web-based questionnaire to collect and assess data from two discrete populations. A self-reporting questionnaire (SRQ-20) was used to pre-assess the respondents’ general wellness and health status. Statistical significance was established using the independent t-test. Principal component analysis was used to identify the major symptoms associated with EHS, whereas the EMF sources were analyzed using an independent sample t-test with bootstrapping. Based on the SRQ-20, traditional BPO personnel encounter health risks with statistically higher severity (p < 0.05) than their remote counterparts which may infer that the two different working settings possibly have distinct effects on the health of the workers. However, upon further evaluation, the two distinct populations both exhibited negligible to moderate indications of EHS symptoms in separate environments. A significant difference in the perception of BPO workers is observed regarding the intensity of the effects of EMF across all possible sources except three specific devices: a computer, a television, and a television or radio transmitter. However, the source analysis indicates that the influence of EMF-emitting devices on the EHS of employees is low to negligible in both occupational settings. The study concluded that there is an absence of potential health risks stemming from exposure to EMF in both occupational settings for BPO employees. Considering the negligible impact of EMF exposure on EHS symptoms, BPO industries possess the flexibility to choose between the two work setups, as both environments do not pose significant EMF-related occupational health and safety threats.

Full textAbstract:
The aviation maintenance mechanic faces a multitude of occupational hazards each day due to the complex nature of the work they perform on aircrafts. The most common problem reported by aviation maintenance mechanics was work related musculoskeletal disorders (WMSDs). Studies have shown that aviation maintenance mechanics suffer WMSDs, most often affecting the back, head, neck and lower extremities. The objective of this study is to assess the risk of WMSDs and propose innovative engineering control of ergonomic hazards associated with aviation maintenance work in a local aviation maintenance hanger. The ergonomic assessment tool used was the Rapid Entire Body Assessment (REBA). This ergonomic assessment tool uses a systematic process to evaluate whole body postural and risks associated with job tasks. Using the REBA worksheet, the evaluator assigns a score for each of the following body regions: wrists, forearms, elbows, shoulders, neck, trunk, back, legs, and knees. The scores for each of these body parts vary. The lower arm score can either be valued as a 1 or 2. The neck and wrist REBA score can range from 1 to 3. The legs are scored 1 to 4. The trunk is on a scale of 1 to 5 with the upper arm stretching as high as a score of 6. Although these scores have different boundaries, the lower they are, the better. Scoring a 1 in all these categories would ensure the workplace is ergonomically friendly and free of wide exposure to WMSDs. The assessment body region score was complied with the risk factor variables, (force/load score, coupling score and activity score) generating a single score that represents the risk level of WMSDs. This individual number tells the evaluator how urgent change is needed. After observing the aviation maintenance mechanics repairing an aircraft engine, an ergonomic risk assessment of the mechanic was conducted using the REBA tool. The final ergonomic assessment resulted in an average REBA score of 9, which represents the risk level of WMSDs. This score indicates that aviation mechanics are at a high risk of WMSDs. Interventions are recommended to reduce the risk of harm to aviation maintenance mechanics. Our study results show that aviation mechanics working at the assessed maintenance hanger are at high risk of WMSDs due to improper engineering controls. The aviation mechanics are subjected to musculoskeletal pain while working in awkward positions and repetitively repeating tasks with no ergonomic benefits. Implementing the recommended engineering controls that re-engineer work practices, processes, posture and body movement will reduce the potential risk of WMSDs. Utilizing ergo chairs, anti-fatigue mats, and ergonomically designed tools will improve the REBA score, resulting in low risk. The common theme of poor posture and lack of ergonomic friendly tasks throughout the worksite will be reduced to an acceptable level through ergonomic interventions.

Full textAbstract:
In the original proposal we planned to focus on two proteins related to the actin cytoskeleton: TCH2, a touch-induced calmodulin-like protein which was found by us to interact with the IQ domain of myosin VIII, ATM1; and ERD10, a dehydrin which was found to associate with actin filaments. As reported previously, no other dehydrins were found to interact with actin filaments. In addition so far we were unsuccessful in confirming the interaction of TCH2 with myosin VIII using other methods. In addition, no other myosin light chain candidates were found in a yeast two hybrid survey. Nevertheless we have made a significant progress in our studies of the role of myosins in plant cells. Plant myosins have been implicated in various cellular activities, such as cytoplasmic streaming (1, 2), plasmodesmata function (3-5), organelle movement (6-10), cytokinesis (4, 11, 12), endocytosis (4, 5, 13-15) and targeted RNA transport (16). Plant myosins belong to two main groups of unconventional myosins: myosin XI and myosin VIII, both closely related to myosin V (17-19). The Arabidopsis myosin family contains 17 members: 13 myosin XI and four myosin VIII (19, 20). The data obtained from our research of myosins was published in two papers acknowledging BARD funding. To address whether specific myosins are involved with the motility of specific organelles, we cloned the cDNAs from neck to tail of all 17 Arabidopsis myosins. These were fused to GFP and used as dominant negative mutants that interact with their cargo but are unable to walk along actin filaments. Therefore arrested organelle movement in the presence of such a construct shows that a particular myosin is involved with the movement of that particular organelle. While no mutually exclusive connections between specific myosins and organelles were found, based on overexpression of dominant negative tail constructs, a group of six myosins (XIC, XIE, XIK, XI-I, MYA1 and MYA2) were found to be more important for the motility of Golgi bodies and mitochondria in Nicotiana benthamiana and Nicotiana tabacum (8). Further deep and thorough analysis of myosin XIK revealed a potential regulation by head and tail interaction (Avisar et al., 2011). A similar regulatory mechanism has been reported for animal myosin V and VIIa (21, 22). In was shown that myosin V in the inhibited state is in a folded conformation such that the tail domain interacts with the head domain, inhibiting its ATPase and actinbinding activities. Cargo binding, high Ca2+, and/or phosphorylation may reduce the interaction between the head and tail domains, thus restoring its activity (23). Our collaborative work focuses on the characterization of the head tail interaction of myosin XIK. For this purpose the Israeli group built yeast expression vectors encoding the myosin XIK head. In addition, GST fusions of the wild-type tail as well as a tail mutated in the amino acids that mediate head to tail interaction. These were sent to the US group who is working on the isolation of recombinant proteins and performing the in vitro assays. While stress signals involve changes in Ca2+ levels in plants cells, the cytoplasmic streaming is sensitive to Ca2+. Therefore plant myosin activity is possibly regulated by stress. This finding is directly related to the goal of the original proposal.

This case study engages with the journey of Dhwani Rural Information Systems, a social enterprise that traces its earliest origins back to 2012. Founded by the duo of Sunandan Madan and Swapnil Aggarwal – engineers by training who met while studying for a postgraduate course at the Institute of Rural Management Anand (IRMA) – Dhwani since its inception has been trying to help a range of social sector organizations effectively integrate technology without disrupting the core ways in which these organizations work. Notably, it has been amongst one of the early enterprises in the sector which has taken efforts to understand in-depth the technology-related “pain points” common across organizations, and to bring a degree of standardisation to their solutions. The case builds an appreciation towards the fact that at the core of a successful technology-centric social enterprise, which can offer relevant and affordable digital products and services to the sector, lies building a composite culture that can straddle both the developmental and technological landscapes. Such a culture seeks to combine engineering and consulting skills in equal measure, and seeks to solve problems mindful of the particularities of the developmental sector, while also retaining a service orientation. In particular, the case looks to draw attention to the ideas of hybridity and elasticity that are integral to such a culture and how these have to be sustained against continuous pressures of talent sourcing, compensation, retention, and learning and development. In a short period of time, Dhwani has become a mature set-up with a clear sector-agnostic product and service value proposition to the sector, with a team strength of over 120 people and over 50 projects, and a variety of organizations, including nonprofits, philanthropies, CSR divisions and governments as clients. Therefore, the experiences of the founders and members of the team offer valuable lessons for other like-minded practitioners. At the same time, to researchers in the field of social enterprise the case may provide a more granular view of important aspects of culture-building in emerging social enterprises. The fact that such enterprises have to draw from a talent pool in constant competition with their private sector counterparts imparts added force to the above considerations.
