Full textAbstract:
The purpose of this study was to determine the correlation among three hand strength measurement methods: Hand dynamometer, MDD (Middle Digital Extension Isokinetic Dynamometer), and Cybex. Five students (2 males, 3 females) from Ball State University were asked to participate in this study. Both right and left lower arm data were collected from these subjects. A Cybex 340 (Lumax Cor.) was employed to determine wrist flexion and extension isokinetic peak torque, total work, and power at 30 degrees/second and 60 degrees/second. A MDD was used to determine third digit eccentric torque, work, and power. A hand dynamometer (Lafayette Instrument Co., Model 76618) was used to determine grip force. Pearson product moment correlation coefficients were used to determine correlation among these variables. Significant correlations were noted between isometric grip strength and isokinetic 30 and 60 degrees/second wrist flexion power, as well as between isometric grip strength and isokinetic 30 degrees/second wrist extensor power. The results of this study indicate there is very little relationship between the three clinically used measurement tools.School of Physical Education

Full textAbstract:
The purpose of this study was to explore utility of handgrip strength measured by the hand-grip dynamometer for assessment of nutritional status in protein-calorie malnutrition. The first study included six subjects (all right-handed), who had grip strength measured daily for five days, then weekly for three weeks. Intra-individual variability was approximately 10%. No learning or training effect was observed. Change in leg position from feet on the floor to elevation of feet made no significant difference in grip-strength measurement. In Phase Two, 43 healthy adult subjects (three left-handed) prior to elective surgery, height was significantly related to handgrip strength (r = 0.82, p < 0.001). Males were stronger than females. After surgery, the non-dominant hand lost significant strength (2.68 kilograms) and recovered more quickly than the dominant hand. Multiple regression analyses provided predictive equations for pre-surgery left hand-grip strength using age, sex, and height (R² = 0.77); from age, sex, hand measured, and grip strength two days after surgery or three days after surgery (R² = 0.89 for each). Ten sequential grip-strength measurements analyzed by repeated measures analysis of variance with orthogonal comparisons showed a difference in measurements between hands as well as before and after surgery. The slope of the measurement line was more linear before and three days after surgery, but more quadratic in shape two days after surgery. The effects seen by type of surgery were inversion of the slope of right hand sequential measurements two days after knee surgery and before-surgery drop and increase from trial five to trial seven in left hand sequential measurements of knee and vaginal hysterectomy subjects. In a six-month-long case study, grip-strength measurements were followed in a seriously-ill 68-year-old patient hospitalized for surgical repair of hiatal hernia and mucous fistula who underwent several periods of nutritional depletion. Grip strength varied throughout the period (although not differently from healthy subjects), but did not directly parallel changes in serum albumin or prealbumin. The conclusion was that hand strength measured by the handgrip dynamometer did not change enough with fasting and surgery from normal day-to-day variability to be useful for nutritional assessment.

Full textAbstract:
Bakgrund: Bålstabilitet är nödvändigt för att hålla balansen och möjliggör kraftöverföring genom kroppen. Detta gör bålstabilitet viktigt i vardagliga sysslor, sportutföranden och för att minska risken för skada. En bättre förståelse över bålstabiliteten i olika sporter kan utveckla träningsprogram, inte bara för att förbättra bålstabiliteten, utan även för att förbättra den generella prestationen. Syfte: Syftet med denna studie var att undersöka skillnader i båluthållighet mellan unga kvinnliga ryttare och fotbollsspelare, och associationen med handgrepp styrka och rotationsrörlighet i ryggen. Metod: Båluthålligheten undersöktes med McGill’s båluthållighets test, mellan kvinnliga ryttare (n = 10) och fotbollsspelare (n = 10), ålder 16 – 20. Handgreppsstyrkan undersöktes med en handdynamometer och användes som en indikation av generell styrka. Ryggrotations testet undersöktes men en Myrinmätare. Shapiro-Wilks användes för att bekräfta normalfördelning av data. Oberoende t-test användes för att jämföra båluthållighet (sek.) mellan ryttarna och fotbollsspelarna. Signifikansnivån fastställdes till <0,05. Ett styrkeförhållande räknades ut (kg/kg kroppsvikt) och Pearsons korrelationskoefficient användes sedan för att undersöka associationen med båluthållighet (sek.). Pearsons korrelationskoefficient användes också för att undersöka associationen mellan medelvärdet av ryggrotation (°) och båluthållighet (sek.). Hög korrelation fastställdes när r> (0,7), måttlig korrelation när r = (0,3 – 0,7) och låg korrelation när r <0,3. Resultat: Resultaten visade att ryttarna hade bättre uthållighet i bålextensionen, jämfört med fotbollsspelarna (p = 0,006). Lateralflexionen av bålen visade ingen skillnad mellan ryttarna och fotbollsspelarna (p = 0,924; p = 0,423). Handgrepp styrkan visade måttlig korrelation med bålextensionen (r = 0,631; r² = 0,398) och båda sidor av lateralflexionen av bålen (r = 0,411; r² = 0,169; r = 0,615; r² = 0,378). Rotationsrörligheten i ryggen visade låg korrelation med samtliga båluthållighets tester (r >0,3). Slutsats: Resultaten indikerar få skillnader mellan ryttare och fotbollsspelare, vilket inte är tillräckligt för att fastställa någon slutsats. Korrelationen mellan handgreppsstyrkan och båluthållighet indikerar att bättre bålstabilitet associerar med mer generell styrka.Background: Core stability is necessary to keep balance and enables force to be transmitted through the body. This makes core stability important in everyday chores, sport performance and to reduce risk of injuries. A better understanding of the core stability in different sports can develop athletes training programs, not only to improve the core stability itself, but also to improve overall performance. Aim: The aim of this study was to examine the differences in core endurance between young female horseback riders and soccer players, and the core endurance association with hand grip strength and spinal rotation mobility. Methods: The McGill’s core endurance test was used to examine the core endurance between female horseback riders (n = 10) and soccer players (n = 10), age 16-20. The hand grip strength was examined with a hand grip dynamometer and was used to get an indication of overall body strength. The spinal rotation mobility was examined with a Myrin goniometer. Shapiro-Wilks was used to confirm the normality of the data. Independent sample t-test was used to compare core endurance time (sec.) between the horseback riders and the soccer players. The significant level was set at < 0.05. A strength ratio was calculated (kg/kg body weight), and the Pearson’s correlation coefficient was used for examining the association to core endurance (sec.). Pearson’s correlation coefficient was also used to examine the association between the spinal rotation mobility (°) and core endurance (sec.). High correlations were set at r > (0.7), moderate when r = (0.3- 0.7) and low when r < (0.3). Results: The result showed that horseback riders had better endurance in the trunk extensor test than the soccer players (p = 0.006). Hand grip strength showed moderate correlation with the endurance time of the trunk extensor test (r = 0.631, r² = 0.398), and with the lateral flexor tests (r = 0.411, r² = 0.169; r = 0.615, r² = 0.378). Low correlation was shown with the trunk flexor test (r = 0.197, r² = 0.039). The spinal rotation mobility test showed low correlation with all the core endurance tests (r >0.3). Conclusion: The results indicates few differences between the horseback riders and the soccer players, which is not enough to draw a conclusion. The correlation between hand grip strength and the core endurance tests indicates that a better core stability might be associated to an increased overall body strength.

Full textAbstract:
Bakgrund: Sportfysioterapeuter hjälper atleter att förbättra sport-specifika förmågor. Inom ishockey är slagskottet den skotteknik som producerar den snabbaste puckhastigheten. Handgreppsstyrka har visat sig vara viktig för en hockeyspelares sport-specifika förmågor och klubbrörelser. Skridskohastighet är en viktig variabel sett till hockeyspelares övergripande prestationsnivå. Syfte: Att undersöka den genomsnittliga maximala skotthastigheten, den genomsnittliga maximala handgreppsstyrkan och den genomsnittliga maximala skridskohastigheten hos en grupp manliga svenska elithockeyspelare och undersöka sambandet mellan den maximala skotthastigheten och den maximala handgreppsstyrkan samt skridskohastigheten. Metod: Ett lag på tjugotre manliga elithockeyspelare tillfrågades varav tjugo deltog i studien. Endast utespelare tillfrågades. Tvärsnittstudie med kvantitativ ansats bestående av enstaka mätningar på en grupp. Skotthastighet, handgreppsstyrka och skridskohastighet mättes en gång per testperson vid tre separata tillfällen. Resultat: Sjutton hockeyspelare slutförde studien. Den genomsnittliga maximala skotthastigheten var 128,167 km/h. Den genomsnittliga maximala handgreppsstyrkan var 60,2 kg. Den genomsnittliga skridskohastigheten var 1,405s mätt på en sträcka av 15 meter. Sambandet mellan skotthastighet och handgreppsstyrka var svagt negativt och ej statistiskt signifikant (r=-0,042; p=0,876). Sambandet mellan skotthastighet och skridskohastighet var svagt negativt och ej statistiskt signifikant (r=-0177; p=0,508). Konklusion: De genomsnittliga maximala värdena på skotthastighet, handgreppsstyrka och skridskohastighet är jämförbara med andra studiers värden. Sambandet mellan skotthastighet och handgreppstyrka samt skridskohastighet var svagt vilket pekar på att dessa faktorer inte är en indikator på skotthastigheten vid ett slagskott. Fler studier behövs för att stödja studiens resultat.Background: Sportsfysiotherapists help athletes improve their sport-specific abilities. In ice-hockey, the slap shot is the shot-technique that produces the greatest puck velocity. Hand grip strength have shown to be important to hockey players sport-specific abilities and stick movements. Skating speed is an important variable for the hockey players overall performance. Aim: To investigate the mean hand grip strength, skating speed and shooting speed on a group swedish male elite ice-hockey players and investigate the correlation between these factors. Methods: A team of twentythree male elite hockey players were asked to participate in the study. Twenty players participated. A cross-sectional study with a quantitative approach consisting of single measures on one group. Puck velocity, handgrip strength and skating speed were measured one time per player on three separate sessions. Results: Seventeen hockey players completed the studie. The mean puck velocity was 128,167 km/h. The mean hand grip strength were 60,2 kg. The mean shooting speed were 1,405s measured on a distance of 15 meters. The correlation between puck velocity and hand grip strength were not statistically significant weak negative (r=-0,042; p=0,876). The correlation between mean puck velocity and shooting speed were not statistically significant weak negative(r=-0,177; p=0,508). Conclusion: The mean maximal values of puck velocity, hand grip strength and shooting speed are comparable with similar values from other studies. The correlation between puck velocity and hand grip strength and shooting speed were weak which indicate that these factors do not affect the puck velocity from a slap shot. Further studies are needed to strengthen this study's result.

Elektroneurografi är en undersökningsmetod som används för att undersöka nervledingskapaciteten i perifera nerver. Det är en metod som ofta används på sjukhuskliniker vid diagnostisering av perifera nervsjukdomar. Syftet med studien är att undersöka om det finns en signifikant skillnad i motorisk och sensorisk nervledningshastighet, amplitud och F-respons mellan dominant och icke-dominant hand. I studien undersöktes det även om en korrelation finns mellan handgreppsstyrka och svarsamplitud från motorisk elektroneurografi. I studien deltog 26 testpersoner från biomedicinska analytikerprogrammet i termin 6. Testpersonernas genomsnittsålder är 24 år (range 21-32 år), och testpersonernas kroppslängd är i genomsnitt 169 cm (range 155- 185). Elektroneurografi utfördes motoriskt och sensoriskt på nervus medianus bilateralt. Handgreppsstyrka undersöktes bilateralt med Jamar Hydraulic Hand dynamometer. För samtliga mätvariabler bestämdes signifikantnivån till α=0,05. Resultatet visar att det finns en signifikant skillnad i sensorisk nervledningshastighet, motorisk amplitud och sensorisk amplitud mellan dominant och icke-dominant hand. Sensorisk nervledningshastighet är högre i icke-dominant hand, medan motorisk och sensorisk amplitud är högre i dominant hand. Däremot kan inte en signifikant skillnad påvisas i motorisk nervledningshastighet, FM-latens samt antalet F-svar mellan dominant och icke-dominant hand. Resultatet visar att det inte finns någon korrelation mellan handgreppsstyrka och amplitud i motorisk elektroneurografi. I dag används samma referensvärden för dominant och icke-dominant hand. Den här studien visar att det kan finnas ett värde i att utforma referensintervall som baseras på handdominans.Electroneurography is an examination method used for examining the nerve conduction capacity of the peripheral nerve. The method is often used in hospitals in the diagnosis of peripheral nerve injuries. The aim of this study is to examine if there is a significant difference in motor and sensory nerve conduction velocity, amplitude, and F-response between dominant and non-dominant hands. The correlation between hand grip strength and the amplitude in motor electroneurography was also examined in this study. The study involved 26 students from Biomedical Scientist Programme term 6. The average age of the participants is 24 years (range 21-32 years), and the participants body length is on average 169 cm (range 155-185 cm). Electroneurography was performed on the median nerve bilaterally. Hand grip strength was examined bilaterally with Jamar Hydraulic Hand dynamometer. For all measurement variables, the significant level was determined to α=0,05. The result shows that there is a significant difference in sensory nerve conduction velocity, motor amplitude, and sensory amplitude between dominant and non-dominant hands. Sensory nerve conduction velocity is higher in non-dominant hand, while motor and sensory amplitude is higher in dominant hand. However, a significant difference cannot be detected in motor nerve conduction velocity, FM-latency, and the number of F-responses between dominant and non-dominant hands. The result shows no correlation between hand grip strength and the amplitude in motor electroneurography. Today, the same reference values are used for dominant and non-dominant hands. This study shows that there may be a value in creating reference intervals based on hand dominance.

Falls, Candice. "FRAILTY IN PATIENTS UNDERGOING LEFT VENTRICULAR ASSIST DEVICE IMPLANTATION." UKnowledge, 2019. https://uknowledge.uky.edu/nursing_etds/47.
Full textAbstract:
Heart failure is a progressive condition that affects over 5.7 million Americans and costs associated with heart failure account for 2-3 % of the national health care budget. The high rates of morbidity and mortality along with increased costs from readmissions associated with advanced heart failure have led to the exploration of advanced treatments such as left ventricular assist devices (LVADs). LVADS have demonstrated morbidity and mortality benefit but cost remains extensive with costs per quality-adjusted years > $400,000. With this in mind, it is important to identify those who are most likely to benefit from an LVAD to avoid unfavorable outcomes and cost. Although general guidelines and criteria for patient eligibility have been established, choosing patients for LVAD implantation remains challenging. A new focus on patient selection involves the presence of frailty. While frailty has been studied in the elderly population and in patients undergoing cardiac surgery, frailty in patients undergoing left ventricular assist device (LVAD) remains controversial. The purpose of this dissertation was to examine measures of frailty in patients undergoing LVAD implantation. The specific aims of this dissertation were to: (1) identify a feasible frailty measure in adults with end-stage heart failure who underwent LVAD implantation by testing the hypothesis that frailty would predict 30 day rehospitalization rates using Fried’s criteria, Short Physical Performance Battery test, handgrip strength, serum albumin and six minute walk test (2) Determine whether frailty measures improve 3 months post LVAD implantation (3) compare sensitivity of these three measures to change in frailty.
Surgical approaches, including heart transplantation and LVAD implantation, for patients with end-stage heart failure was discussed in this dissertation. Data from two subsets of participants who underwent LVADS at the University of Kentucky between 2014 and 2017 were included in the analysis for this dissertation. In the first study, we found that none of the measures are good predictors of frailty in patients with advanced heart failure who undergo LVAD implantation. Handgrip was the only marker of frailty that predicted 30 day readmission but the relationship was a negative association. In the second study, six-minute walk and low serum albumin levels reflect short-term improvement in frailty. These simple measures may be used to determine those patients who are responsive to LVAD implantation.
The findings of these studies filled some gaps in our understanding of markers of frailty in patients undergoing LVADs. We gained a better understanding of which markers of frailty are likely to improve in most people after LVAD implantation and thus frailty should not preclude candidate selection for an LVAD. Subsequently, more research is needed to investigate these markers and outcomes.

The grasp is recognized as a useful tool to identify the level of development and the degree of disability of an individual on clinical practice; however the data available in the literature about the maximum grip strength in children and adolescents should be periodically extended. In addition, there is no quantitative researches on literature about the pattern of development grasp of typical children. Objective: To characterize the handgrip of typical children aged between 5 and 10 years. Methods: The project was divided into two studies. On study 1, healthy children, aged between 5 and 10 years were divided into six groups according to age. Participants were subjected to a single assessment to obtain the anthropometry data (height and weight) and grip strength data (maximum grip strength). On study 2, a device was developed to characterize, both qualitatively and quantitatively, the standard grip for the task of drinking water. To test the device, they were randomly selected 16 participants from the study 1. Results:(Study 1) Significant increase in maximum grip strength throughout the ages was observed. The boys were stronger than girls. The dominant hand was stronger than the non-dominant hand for both genders. For girls, there was a strong correlation between maximum grip strength with the hand length and body mass. For boys, therewas a strong correlation with the length of the hand and height. (Study 2) The grip pattern data were measured using a device whose shape was made to a similarly transparent glass. Final Considerations: This study provides reference values for maximum grip strength of children aged between 5 and 10 years. The maximum grip strength increases throughout the ages. The boys are stronger than girls, regardless of age and tested hand. In addition, it was developed a prototype device that ultimately could providea detailed evaluation of the strategies used in the handgrip for a functional task. Thus expanding the understanding of the mechanisms related to modulation of grip when handling objects will assist in identifying the pathogenesis of motor disorders in children with developmental disorders without the values are underestimated by the expected for their age.
Embora seja reconhecida a importância clínica da preensão como ferramenta útil para identificar o nível de desenvolvimento e o grau de deficiência de um indivíduo, os dados disponíveis na literatura quanto à força de preensão palmar máxima em crianças e adolescentes devem ser periodicamente ampliados. Além disso, não há na literaturaestudos quantitativos sobre o desenvolvimento do padrão de preensão de crianças típicas em idade escolar. Objetivo: Caracterizar a preensão de crianças típicas com idade entre 5 e 10 anos. Métodos:O projeto foicomposto por dois estudos. No estudo 1, participaram criançassaudáveis, com idade entre 5 e 10 anos, divididas em seis grupos, de acordo com a faixa etária. Os participantes foram submetidosa uma única avaliação, na qual foram obtidosos dados referentes à antropometria (estatura e massa corporal) e dinamometria (força de preensão palmar máxima). No estudo 2, foi desenvolvido um dispositivo que caracterizaqualitativa e quantitativamente, o padrão da preensão durante a tarefa de beber água. Para testar o dispositivo, foram selecionados aleatoriamente (sorteio) 16 participantes do Estudo 1. Resultados: (Estudo 1) Foi observado aumento significativo da força de preensão palmar máxima ao longo das idades. Os meninos foram mais fortes do que as meninas. A mão dominante foi mais forte do que a não dominante para ambos os gêneros. Para as meninas, houve forte correlação da força de preensão palmar máxima com o comprimento da mão e a massa corporal. Para os meninos, houve forte correlação com o comprimento da mão e a estatura. (Estudo 2)Os dados referentes ao padrão de preensão palmar foram aferidos por meio de um dispositivo, cujo formato foi confeccionado similarmente a um copo transparente. Considerações Finais: Este estudo fornece valores de referênciada força de preensão palmar máximade crianças com idade entre 5 e 10 anos. A força de preensão palmar máxima aumenta ao longo das idades. Os meninos são mais fortes do que as meninas, independente da idade e da mão testada. Além disso, foi desenvolvido o protótipo de um dispositivo que futuramente poderá fornecer uma avaliação detalhada das estratégias utilizadas na preensão manual durante uma tarefa funcional.Assim, a ampliação do entendimento dos mecanismos relacionados à modulação da preensão duranteamanipulação deobjetosauxiliará na identificação da patogenia das alterações motoras de crianças com distúrbios do desenvolvimento sem que os valores obtidos sejam subestimados pelo esperado para a sua idade.

Full textAbstract:
Patients in the intensive care unit (ICU) setting are prone to develop muscle weakness and the causes are multi-factorial. Muscle strength in adult, critically ill patients on mechanical ventilation decreases with immobility. The influence of muscle strength on different muscle groups and its influence on progressive mobility in the adult, critically ill patient on mechanical ventilation has not been examined. Identifying muscle strength in this patient population can benefit overall muscle health and minimize muscle deconditioning through a progressive mobility plan. The objective of this dissertation was to describe muscle strength in different muscle groups and to describe the influence of muscle strength on mobility in critically ill adult patients on mechanical ventilation (MV). Fifty ICU patients were enrolled in this descriptive, cross sectional study. Abdominal core, bilateral hand grip and extremity strength was measured using three measurement tools. Mobility was measured using the following scale: 0=lying in bed; 1=sitting on edge of bed; 2=sitting on edge of bed to standing; 3=walking to bedside chair and 4=walking >7 feet from the standing position. Predictors of mobility were examined using stepwise regression. Abdominal core, bilateral hand grip and extremity strength demonstrated statistically significant relationships with all variables. Extremity strength accounted for 82% of the variance in mobility and was the sole predictor (β=0.903; F=212.9; p=0.000). Future research addressing the outcomes of implementing a mobility protocol in this patient population and prioritizing when such a protocol should be implemented would be beneficial to ongoing plans to decrease MV, ICU and hospital days. Muscle strength tests implemented at the bedside are crucial to implementing a progressive mobility plan for critically ill adults while they are on MV therapy.

Full textAbstract:
Human ageing is accompanied by characteristic metabolic and endocrine changes, including altered hormone profiles, insulin resistance and deterioration of skeletal muscle. Obesity and diabetes may themselves drive an accelerated ageing phenotype. Untangling the causal web between ageing, obesity and diabetes is a priority in order to understand their aetiology and improve prevention and management. The role of biological ageing in determining the risk of obesity and associated conditions has often been examined using mean leukocyte telomere length (LTL), a marker of replicative fatigue and senescence. However, considering phenotypes which represent different domains of biological and functional ageing as exposures for obesity and related traits could allow the elucidation of new understudied phenotypes relevant to cardio-metabolic risk in the wider population. This PhD considers the causal role of (1) hand grip strength (HGS), a marker of overall strength and physical functioning, and (2) resting energy expenditure, an indicator of overall energy metabolism and the major component of daily energy expenditure, in cardio-metabolic risk. I also characterise a new and readily-quantifiable marker of age-related genomic instability, mosaic loss of the Y chromosome (mLOY). Observational evidence implicates each of these phenotypes in cardio-metabolic conditions and intermediate phenotypes. However, it is not possible to infer causality from these observational associations due to confounding and reverse-causality. Mendelian randomisation offers a solution to these limitations and can allow the causal nature of these relationships to be investigated. Using population-based data including UK Biobank, this thesis presents the first large-scale genetic discovery effort for each trait and provides new biological insight into their shared and separate aetiology. I used identified variants to investigate the bidirectional causal associations of each trait with cardio-metabolic outcomes, intermediate phenotypes and other related traits such as frailty and mortality. In total I identified 16 loci for hand grip strength, 19 for mLOY, and one signal for REE. I have shown that HGS is likely to be causally linked to fracture risk, and I have identified the important shared genetic architecture between mLOY, glycaemic traits and cancer. I have also demonstrated that at least one known genetic variant contributing to obesity risk acts partially via reduced REE. Overall the findings of my PhD contribute to our wider understanding of the aetiological role of ageing processes in metabolic dysfunction, and have implications for both basic science and translational applications.

Contexte :Le conditionnement précédant la greffe de cellules souches hématopoïétiques (CSH) a été associé avec des taux élevés de malnutrition meme à 100 jours après la greffe. Objectif: Cette étude évalua l'impact du conseil nutritionel fournie à la sortie de l'hôpital sur l'état nutritionnel,100 jours après la greffe de CSH (dit T4).Conception: Il s'agissait d'un essai contrôlé randomisé monocentrique. Les patients adultes étaient randomisés à un groupe témoin (GT) recevant des soins habituels et un groupe d'intervention (GI) recevant des conseils nutritionnels mensuels après la sortie de l’hôpital. Le résultat principal était le score de l'évaluation globale subjective générée par le patient (PGSGA) à T4. La malnutrition était évalué aussi par le score de la société américaine de nutrition parentérale et entérale/Académie de nutrition et diététique (AND-ASPEN).Résultats: 52 participants ont été randomisés (août 2016 jusqu'en août 2017) et 46 ont été analysés [65% d'hommes, 63% de greffes autologues, GI (n = 22), GT (n = 24)]. Les deux groupes etaient comparable au moment de randomization.A T4, le pourcentage de patients bien nourris n'était pas significativement différent entre les groupes selon le PGSGA (72% GI vs 43% GT, p = 0,063). Le pourcentage de patients bien nourris selon AND-ASPEN s'est améliorré à T4 dans le GI (50% vs 14%, p = 0,02) et non pas dans le GT par rapport aux valeurs d'admission. A T4, le GI avait un apport de protéines et de calories plus élevé que le GT(p<0.05).Conclusion:Le conseil nutritionnel après la greffe de CSH a amélioré l’apport en protéines et calories ainsi que le score AND-ASPEN mais non pas le score PGSGABackground: Conditioning preceding Hematopoietic Stem Cell Transplantation (HSCT) has been associated with elevated rates of malnutrition until 100 days post HSCT.Objective: This study aimed to assess the impact of nutritional counseling provided at hospital discharge on nutritional status 100 days post HSCT (defined as T4). Design: This was a single center randomized controlled trial among adult HSCT patients. Around discharge from the hospital, recruited patients were randomized to a Control Group (CG) receiving usual care and to an Intervention Group (IG) receiving nutritional counseling on a monthly basis post discharge.The primary outcome was the Patient Generated Subjective Global Assessment (PGSGA) scores at T4. Malnutrition was also assessed though the American Society for Parenteral and Enteral Nutrition/ Academy of Nutrition and Dietetics malnutrition score.Results: 52 participants were randomized (August 2016 until August 2017) and 46 were analyzed [65% males, 63% autologous HSCT, IG (n=22), CG (n=24)]. Groups were comparable at randomization. At T4, the percent of well-nourished patients was not significantly different between groups when assessed via PGSGA (72% IG vs. 43% CG, p=0.063).The percent of wellnourished patients as per AND-ASPEN criteria improved in IG at T4 (14% vs. 50%, p=0.02) and remained the same in CG (48% vs. 50%, p=1) compared to admission values. IG had higher protein and caloric intake (p<0.05). Conclusion:Nutritional counseling post HSCT improved patients’ protein and caloric intake and AND-ASPEN score but did not significantly improve PGSGA score

Dinamômetros biomédicos são equipamentos utilizados para medir forças exercidas pelas mãos. Com o uso deste tipo de equipamento, é possível realizar avaliações biomecânicas das mãos de pacientes que após cirurgias, acidentes ou patologias osteomioarticulares, tiveram redução na sua capacidade de exercer forças com as mãos. O objetivo deste trabalho foi a implementação de um dinamômetro biomédico ergonômico, de fácil utilização, com capacidade de comunicação com diferentes tipos de dispositivos móveis, como smartphones e tablets. O projeto realizado se constitui no aprimoramento de duas versões anteriores de dinamômetros implementadas no Laboratório de Instrumentação Eletrônica e Engenharia Biomédica da UNESP –Campus de Ilha Solteira. Testes em voluntários utilizando o dinamômetro desenvolvido e um dinamômetro comercial da marca SAEHAN, e posterior análise estatística dos dados revelam uma excelente confiabilidade intra-examinador para o dinamômetro desenvolvido, com coeficiente de correlação intraclasse médio de 0,95 entre os diferentes grupos analisados, e de 0,98 para o dinamômetro SAEHAN. A análise estatística revela também uma excelente confiabilidade concorrente para as medidas realizadas pelo dinamômetro desenvolvido em relação às do dinamômetro SAEHAN, sendo de 0,93 para mãos dominantes e 0,92 para mãos não dominantes. Assim, o dinamômetro desenvolvido é confiável, válido e comparável com o dinamômetro SAEHAN quando adotados os mesmos procedimentos de exame de preensão palmar.

Previous issue date: 2012-03-02BACKGROUND: Protein energy wasting commonly occur in patients with chronic kidney disease. Changes in muscle function arise even before changes in anthropometric and biochemical parameters.Thus, a method for evaluating muscle function and strength becomes essential for these patients. OBJECTIVES: To evaluate the handgrip strength (HGS) and its association with nutritional status of patients with chronic kidney disease on hemodialysis. METHODS: A cross-sectional study conducted between May and July/2011. The sample included 90 patients, 48.8% male and 51.2% female. The HGS was performed three times with a hydraulic hand dynamometer (Takei) in the arm without fistula. For each patient were considered the best strength measure. Values lower than percentile 10 were considered as low HGS. The nutritional status diagnosis was given by Subjective Global Assessment (SGA). RESULTS: The average age was 52 ± 14.7 years. The hypertensive nephrosclerosis was the most frequent cause of chronic kidney disease (31.1%). The average HGS was among 32.0 ± 8.7kgf in men and 20.7 ± 6.1kgf in women (p<0.001). 11.3% of men and 21.7% of woman were classified as moderatey malnourished by SGA, 31.8% and 34.8% of men and women, respectively, were classified with low muscle function. Low HGS was associated with time on hemodialysis for men and showed good sensitivity (73.3%) and specificity (74.7%) for malnutrition diagnosis. In multiple logistic regression analysis, low-power handgrip strength prevalence was two times higher (PR =2.00, 95% CI: 1.19 to 3.34) for patients classified as moderate malnourished by SGA. CONCLUSION: This study showed high prevalence of low muscle function and good association between HGS and SGA in patients with chronic kidney disease on hemodialysis classified by dynamometry. It is suggested that HGS, an inexpensive and noninvasive measurement, can be used in clinical practice as a screening tool of nutritional status. It is sensitive for malnutrition diagnosis.
INTRODUÇÃO: A desnutrição energética proteica é frequente nos pacientes com doença renal crônica. As alterações da função do músculo surgem antes das modificações dos parâmetros antropométricos e bioquímicos. Assim, torna-se importante um método para avaliar a função e força muscular. OBJETIVOS: Avaliar a força de aperto de mão e sua associação com estado nutricional de pacientes com doença renal crônica em hemodiálise. MÉTODOS: Estudo transversal, realizado em maio a julho de 2011. Foram incluídos no total 90 pacientes. A Força de Aperto de Mão (FAM) foi realizada três vezes com dinamômetro hidráulico no braço sem a fístula. Considerou o melhor desempenho da medida da FAM. Os valores menores que o percentil 10 foram considerados como baixa FAM, de acordo com ponto de corte proposto para população para população de Niterói, Rio de Janeiro, Brasil. O diagnóstico do estado nutricional foi realizado por meio da Avaliação Subjetiva Global (ASG). RESULTADOS: Do total da amostra 48,8% eram do sexo masculino e 51,2% do sexo feminino. A média de idade foi 52±14,7 anos. A nefroesclerose hipertensiva foi a causa mais frequente de doença renal crônica (31,1%). A FAM média entre os homens foi de 32,0 ± 8,7kgf e entre as mulheres 20,7 ± 6,1kgf (p=<0,001). Pela classificação da ASG, 11,3% dos homens e 21,7% das mulheres foram classificados como desnutridos moderados; 31,8% e 34,8% dos homens e mulheres, respectivamente, foram classificados com baixa força de aperto de mão. Os homens com maior tempo em hemodiálise apresentaram baixa FAM. A sensibilidade (73,3%) e especificidade (74,7%) da FAM para o diagnóstico de desnutrição foi adequada. Na regressão logística múltipla a prevalência de baixa força de aperto de mão foi duas vezes maior (RP=2,00; IC95%: 1,19-3,34) para os pacientes classificados com desnutrição moderada pela ASG. CONCLUSÃO: Este estudo mostrou alta frequência de baixa FAM e associação da FAM com a ASG em pacientes com doença renal crônica em hemodiálise. Sugere-se que a FAM, uma medida barata e não invasiva, possa ser usada na prática clínica como ferramenta de triagem do estado nutricional, pois apresenta boa capacidade de predizer a desnutrição.

Full textAbstract:
Hand grip strength (HGS) is a new nutritional assessment parameter proposed by American Society for Parenteral and Enteral Nutrition (ASPEN) and the Academy of Nutrition and Dietetics (the Academy) for diagnosis of adult malnutrition related to acute illnesses, chronic diseases or starvation. Identification of ≥2 of the following conditions is considered to be malnourishment – weight loss, loss of muscle mass, loss of subcutaneous fat, fluid accumulation, diminished HGS and inadequate energy intake. HGS is also a marker of sarcopenia, a condition defined by low muscle mass and low muscle strength or performance, as identified by the European Working Group on Sarcopenia in Older People. It has also been shown that lower HGS is associated with deficits in activities of daily living (ADL) and mobility. HGS is emerging as an important screening tool especially in the malnourished and aging population. This research evaluates the applicability of HGS as a nutrition screening tool in long-term care older adults.
Data from a total of 129 participants age ≥60 years involved in an ongoing walking program in long-term care facilities in Saskatoon available for analysis at the time this work was undertaken. Participants were randomly assigned for an intervention period of 16 weeks to one of three study groups: 1) Usual Care Group, 2) Interpersonal Interaction Group, and 3) Walking Program Group. Activity of daily living, cognition and depression scores and hand grip strength were recorded at baseline and every eight weeks. Information on vitamin D intake status prior to study commencement was also collected. This study provides values of low grip strength similar to those defined for the risk of sarcopenia in frail older adults. Stronger baseline HGS was correlated with greater ADL independence in females (B=0.079, P=0.044). Greater ability to eat at baseline was also associated with stronger grip in females when cognition status was taken into consideration. Baseline ADL (B=-0.024) and HGS (B=1.004) were significant predictors of subsequent ADL and HGS, respectively, in males (P<0.01). Baseline HGS was associated with subsequent ADL and HGS in females, but such association was modified by other covariates. In summary, if grip strength is to be used as a nutritional screening tool in long-term care facilities, dietitians shall be cautious of other factors such as the residents’ cognitive status and age and use in conjunction with other nutrition assessment methods.

This study investigated the effects of hand size on grip force for school children. A total of 114 subjects (61 males and 53 females) were recruited. A completely randomized design was conducted for grip strength. The size of the hand and other body parts were assessed via direct measures, measuring handedness and non-dominant hand grip strength values under 180 degrees and 90 degrees, two kind of posture.The results showed that Fifth and sixth grade students handedness small size differences of the non-dominant hand hand, the average 11-year-old children the hand size larger than the 10-year-old children, with increasing age, the size of the hand lengthas well as with growth.The maximal grip strength for the subjects was 43.5kgf on dominant hand with the 180 degree posture. The minimal was 7 kgf on non-dominant hand with the 180 degree posture. There was no significant difference between males and females. The sixth graders had significantly higher values than the fifth graders on all four grip measures conditions. The results also showed that the grip strength was significantly (p<0.01) associated with hand length, palm length, hand width, hand circumstance, and the length of the tiger's mouth and the length of all the fingers. A linear regression model was established using hand size, age, gender, and elbow posture as independent variables and grip strength as the dependent variable. The coefficient of determination of this model was 67.3%.

Cumulative trauma disorders（CTDs）of the upper extremities are one of the major ergonomics parts of research. Gripping and pinching both are the common risk factors which are caused the hand and wrist CTDs. The evaluation of grip strength and pinch strength are essential in order to provide information which is related to work capacity. If the muscle strength doesn’t match the tasks, it can cause serious overuse injuries. This information can be used for designing equipments and workstations to fit the strength in order to reduce the force relative to the muscular strength available. This study evaluates the effect on the grip strength and the key pinch strength on the glove material and the glove thickness. Three commercially available glovebox gloves, namely butyl, hypalon and neoprene in 0.015 and 0.03 inch thickness. Using the stepwise regression and back-propagation neural network（BPNN）to model the grip and key pinch strength. The results show that the gloved hands decrease the grip strength. Both male grip and key pinch strength are batter than female. Thin gloves retain better grip and key pinch strength compared to thick gloves. Butyl material retains better grip strength than hypalon and neoprene materials. Based on the results, 0.015 inch butyl glove is recommended to minimize the effects on grip and key pinch strength. To use the BPNN can get better prediction on grip and key pinch strength.

This study aimed to investigate the effects of glove thickness, hand length and body mass index on grip strength. Thirty-six participations between the age of 20 and 27 were sampled equally from three hand length (ranged between 14.24 and 19.04 cm) strata, and grouped into slim, medium and obese figure types by their body mass index (BMI) ranged between 15.5 and 44.6 kg/m2. The grip strengths of dominant hand of these participations were measured bare-handed, wearing gloves 500, 1000, 2000 and 4000µm thick using T.K.K.5101 grip dynamometer manufactured by Takei Scientific Instruments Co., Ltd. The results of three factors analysis of variance showed significant effects of glove thickness, hand length, BMI and hand length*BMI interaction. The post hoc glove thickness effect analysis indicated that the mean grip strength of 4000µm glove wearing significantly lower than that of bare-handed. The mean grip strength differences between the other glove thickness wearing and bare-handed were insignificant. The results of pair comparison of hand length-BMI interaction effect indicated that for slim group, only the difference between long and medium hand length subgroups was not significant. For obese group, only the difference between long and short hand length subgroups was significant. As for medium figure type group, the differences of all pairs of three hand length subgroups were all significant. Reviewing literature, the investigations of hand length-BMI interaction effect on grip strength were rare; and the results of this study about glove thickness effect on grip strength were roughly consistent with, yet some specifics need further discussions.

This study examines the effects of gender, hand skin temperature (HST) and effort level on the accuracy and precision of both reproduction and estimation of grip strength. Forearm EMGs of dominant hand were monitored on extensor digitorum muscles(ED) and flexor digitorum superficialis(FDS) during exertion. The experimental design is a combination of nested-factorial and split-plot designs. Ten men and ten women were recruited and nested within the gender. The HST includes initial temperature and 14°C , and it is considered as the whole plot. The effort level includes 15, 30, 45, 60, 75, and 90%MVC, and it is considered as the sub-plot. The results indicated the effects of gender, HST, and effort level had significant effects on the accuracy of grip strength reproduction, but only HST had a significant effect on the accuracy of grip strength estimation. For reproduction, females had more accuracy than males did. Around 60~75% MVC, males had a better ability to reproduce, and they overestimated and underestimated as the levels were less and greater than 60~75% MVC. Females had a similar trend but the boundary was around 45~60% MVC. As to the precision, the results revealed the effects of gender and effort level had significant effects on the precision of grip strength reproduction, but only gender had a significant effect on the precision of grip strength estimation. For reproduction and estimation, males had more precision than females did. For reproduction, there is the less precision for 60%MVC of effort level, but there are no significant differences in the others. In the case of EMG, the effects of gender, HST, effort level, and muscle were significant. Females had greater EMG activity than males did during the grip strength reproduction. The EMG activities at initial HST are greater than those at 14°C . As the effort level increased, the EMG activity increased.

Losses of fat free mass (FFM) and muscular strength are closely related, and they are commonly associated with aging process. These reductions must be some of the most important reasons for muscular strength in elderly people, which associated with functional impairment. These FFM losses and muscular strength reduction are denominated sarcopenia. Loss of strength is greater than losses of muscle mass with aging, although disease state and obesity must play a role in this sarcopenic syndrome. It was our aim to analyze the relationship between the classical determinants of strength, such as nutrition, physical activity (PA) and body composition, and hand grip strength (HGS) in older people, additionally compare these parameters between groups with and without disease, healthy group and unhealthy group (HG vs. UHG) or sarcopenic obesity group and non sarcopenic obesity group (SOG vs. NSOG). We also explored determinants of HGS. Methods: A total of 103 subjects (61.16±7.74 years; 70.43±12.33 kg) participated in this transversal study. Body composition was assessed by tetrapolar bioimpedance. Physical activity and nutrition were estimated using questionnaires. Strength was assessed using digital hand grip dynamometer. Pearson’s and Spearman’s coefficients of correlation were used to analyze the relationship between variables. Independent sample T-test and Mann-Whitney’s non-parametric test were utilized to compare differences between groups. Finally, stepwise linear regression was carried in order to estimate the main determinants of handgrip strength.
Results: HG had positive correlation between HGS and activity score (r = 0.286; P< 0.05), total grams of protein intake (r = 0.543; P< 0.01), fat free mass (FFM) (r = 0.852; P< 0.005), fat free mass index (FFMI) (0.748; P 0.0). Negative correlation were found adjusting for age between score house and HGS in SOG (r = -0.391; P < 0.05) and in NSOG (r = -0.383; P < 0.01). The main predictor of HGS was FFM, which explain 68.8% of HGS variability.
In conclusion, these results suggest that high levels FFM and total grams of protein and low percentage of FM and low score of household physical activities are the major determinant of HGS in HG and UHG elderly people even adjusted for age.A perda de massa isenta de gordura (MIG) e a força muscular estão intimamente relacionadas, e estão associados com o envelhecimento. Estas reduções devem ser devidas a algumas das mais importantes razões para a diminuição da força muscular na população idosa, o qual se associa com “impairment” funcional. Estas perdas de MIG e força muscular são denominadas sarcopenia. Normalmente a perca de força de pressão manual (PM) é maior que as percas de massa muscular no envelhecimento; embora as doenças e a obesidade tem sido factores que influencia a perda de força, a sua associação com outros factores do estilo de vida tem sido pouco estudada. O objetivo deste estudo foi analisar as relações entre os determinantes clássicos de força, nutrição, actividade física (AF) e FM. Adicionalmente, comparar estes mesmos parâmetros entre grupos sem (GS) e com doenças (GNS), e com obesidade sarcopénica (GOS) e sem obesidade sarcopénica (GSOS). Também foram analisados os determinantes da FM. Métodos: Um total de 103 sujeitos (61.16±7.74 anos; 70.43±12.33 kg) participaram neste estudo transversal. A composição corporal foi avaliada com bioimpedância tetrapolar. Actividade física e ingestão nutricional foram estimadas com questionários. A FM foi avaliada usando dinamômetro manual. As associações entre variáveis foram avaliadas usando coeficientes de correlação Pearson e Spearman; as diferenças entre grupos foram analisadas utilizando Test-t para amostras independentes e/ou test de Mann-Whitney e procedimento regressão linear (stepwise) múltipla foram usados para estimar os determinantes da FM. Resultados: O GS teve correlações positivas entre FM y AF (r = 0.286; P< 0.05), a ingestão total de proteína em gramas (r = 0.543; P< 0.01), a MIG (r = 0.852; P< 0.005), e o índice de massa isenta de gordura (IMIG) (0.748; P< 0.05). Adicionalmente, correlações negativas ajustadas pela idade foram encontradas entre actividades da casa e FM no grupo de OG (r = -0.391; P < 0.05) e no GSOS (r = -0.383; P < 0.01). Finalmente o principal predictor da FM foi a MIG, que explicou o 68.8% da variabilidade da FM. Conclusões: Os nossos resultados sugerem que elevados níveis de MIG e a ingestão total de proteína em gramas e baixos níveis de massa gorda e actividade de casa são os maiores determinantes de FM em GS e GNS da população idosa ainda quando ajustamos para a idade.

Present study investigates the effect of hand skin temperature on grip strength, pressure-pain, subjective perception of cold, and difference threshold. Ten male and 10 female volunteers took part in this study. There were two experiments designed. The first evaluated the change on pressure-pain measured every 5 minutes and subjective perception of cold measured every minute during a 20min-12oC cold immersion, and the change in grip strength between prior and post this immersion. The pressure-pain additional measured prior to immersion. The second experiment investigated the discriminability of weight difference (measured by difference threshold) between hand skin temperatures at 34 oC and 12 oC as the standard weight was 250g. The results indicated that after 20-min cold immersion hand skin temperature decreased significantly, and grip strength reduced dramatically from 42.7 kg of prior to immersion to 31.7 kg of after immersion. Additionally, subjective perception of cold during this 20-min immersion was increasing and then decreasing. The pressure-pain increased after immersion. Finally, the difference threshold at 34℃ was 3.60％，which was significantly less than that at 12℃ (6.96％).

Objective: Muscle strength decreases as people age. Literature indicates that resistance training could increase muscle strength among the elders. Elastic band resistance training is appropriate for older adults to maintain their muscle strength. Evidence shows that handgrip strength is an crucial predictor for nutrition status and mortality among older people. In this study, a thorough review of studies, evaluating the effectiveness of elastic band resistance training to increasing handgrip strength among older populations was conducted. A meta-analysis on the findings of the selected studies was performed to further evaluate effectiveness of elastic band resistance training in improving handgrip strength. Methods: The following databases were selected: PubMed, EBSCO, Cochrane Library, PEDro, and Airiti Library. The overall effect size was using Review Manager 5.3 (RevMan5.3), which was calculated for all comparisons. Results: The results of the meta-analysis of the literature is I² = 21% and the SMD is 2.29 (95% confidence interval is between 1.44 and 3.13). Since the 95% confidence interval does not include zero, the results show that elastic band resistance training was effective in improving handgrip strength among older populations. Conclusions: Elastic band resistance training has a significant effect in improving the handgrip strength among the elderly.

"Grit” is an evolving concept that has been perceived in different ways, by different people, in different times. The question that should be answered with this WP, to address the risk that grit without ethics can present, is: “Where does the red line stand between grit being a strength or becoming an issue?”. The analysis of the answers to quantitative and qualitative surveys that were conducted will enable to better understand if, when and why people can lose their ethics along their academic or professional journey and grit can become a problem rather than a praised positive character trait.
