ABSTRACT

Muscle strength can be measured through different methods and handgrip strength is one of the most used techniques in epidemiological studies. Given its easy application, high reliability, and low cost, it is considered an important health biomarker. Handgrip strength is associated with adverse health outcomes such as mortality and risk of developing chronic diseases, cardiovascular, respiratory, cancer and dementia. There is a paucity of evidence in Chile about the association of handgrip strength with these health outcomes limiting its visibility and implementation in clinical settings. Therefore, this narrative review summarizes the scientific evidence about the association of grip strength with non-communicable chronic diseases and mortality in middle age and older adults.

ABSTRACT

Abstract This article aims to analyze the association between sleep time and handgrip strength in adolescents belonging to the 1997/1998 São Luís Birth Cohort. This was a cross-sectional study nested in a birth cohort study. One thousand two hundred sixty-nine individuals (18 and 19 years) wore an Actigraph® GTX3+ accelerometer on their wrist 24 hr/day for 7 consecutive days. Handgrip strength was measured using a digital hand dynamometer. We used directed acyclic graphs (DAG) to identify confounding variables. This sample of adolescents was mostly composed of men, with brown skin color, economic class C, which did not work, did not consume alcohol, did not smoke, and never used drugs. The mean value of handgrip strength was 28.2 (±9.3) kgf, and the mean of sleep time was 6 (±1.0) hours per day. The crude analysis showed an association between sleep time and muscle strength. An increase of one hour of sleep reduced the handgrip strength by 1.95 kgf (95%CI:-2.51;-1.39). However, after adjustment for confounders, the association was not maintained (β:-0.07; 95%CI:-0.48;0.36). Sleep time is not associated with handgrip strength in adolescents in São Luís.


Resumo O objetivo deste artigo é analisar a associação entre tempo de sono e força de preensão manual em adolescentes da Coorte de Nascimentos de São Luís 1997/1998. Estudo transversal aninhado a um estudo de coorte de nascimentos. Mil duzentos e sessenta e nove indivíduos (18 e 19 anos) usaram um acelerômetro Actigraph® GTX3 + em seu pulso 24 horas/dia por sete dias consecutivos. A força de preensão manual foi medida por meio de um dinamômetro digital de mão. Usou-se gráficos acíclicos direcionados (DAG) para identificar variáveis ​​de confusão. A amostra de adolescentes foi composta em sua maioria por homens, de cor da pele parda, classe econômica C, que não trabalhava, não consumiam álcool, não fumavam e nunca usaram drogas. O valor médio da força de preensão manual foi de 28,2 (±9,3) kgf, e a média do tempo de sono foi de seis (±1,0) horas por dia. A análise bruta mostrou associação entre tempo de sono e força muscular. O aumento de uma hora de sono reduziu a força de preensão manual em 1,95 kgf (IC95%:-2,51;-1,39). No entanto, após o ajuste para fatores de confusão, a associação não foi mantida (β:-0,07; IC95%:-0,48;0,36). O tempo de sono não foi associado à força de preensão manual em adolescentes de São Luís.

ABSTRACT

Objectives: To understand the importance of hand grip strength (HGS) as a survival predictor in nonagenarians and centenarians. Methods: Longitudinal, observational and analytical study, using HGS measurements obtained during a first evaluation performed in 2016. Participants were nonagenarians and centenarians, randomly selected in various neighborhoods of Porto Alegre (RS) and evaluated in their homes. The time elapsed between the first evaluation and the date of death or last contact (for survivors) was used to calculate the hazard ratio (HR) using survival analysis on simple and adjusted Cox regression models. Results: The sample comprised 212 participants (155 women), of whom 83 (39%) died during follow-up (until August 30, 2019). Using the lowest quartile (25%) for HGS, participants with < 10 kgf for women and 17 kgf for men were considered to have poor HGS performance. In the simple regression model, participants with lower HGS presented a HR of 2.75 (1.76­4.30, p < 0.001) for death. Also in the simple model, participants aged between 90 and 94 years old presented an HR of 0.37 (0.16­0.85, p = 0.019) compared to those aged 100 or older. In the adjusted model, age lost its significance in the presence of HGS. The following were significant predictors in both simple and adjusted models: cognitive performance, calf circumference, ability to participate in social activities, shop, and prepare meals alone, performance in the Timed Up and Go test, and ease to perform activities requiring upper limb strength. Conclusions: HGS was an important independent and modifiable predictor of survival among nonagenarians and centenarians.


Objetivos: Compreender a importância da força de preensão palmar (FPP) como preditor em nonagenários e centenários. Metodologia: Estudo, longitudinal, observacional e analítico, utilizando os resultados da FPP medidos na primeira avaliação realizada em 2016. Os participantes eram nonagenários e centenários, selecionados aleatoriamente em vários bairros de Porto Alegre (RS) e avaliados em suas residências. Os participantes com 10 kgf para mulheres e 17 kgf para homens foram considerados com menor desempenho da FPP. O tempo entre a primeira avaliação e a data do óbito ou último contato (entre sobreviventes) foi calculado para avaliar a Razão de Dano (RD) usando análise de sobrevida por modelos simples e ajustados da Regressão de Cox. Resultados: A amostra foi composta por 212 participantes, 155 mulheres, 83 (39%) faleceram durante acompanhamento (até 30 de agosto de 2019). Na regressão simples, os participantes com menor desempenho na FPP apresentaram RD de 2,75 (1,76 ­ 4,30, p < 0,001). No modelo simples, participantes com idade entre 90 e 94 anos, apresentaram RD de 0,37 (0,16 ­ 0,85, p = 0,019) em relação aos centenários. No modelo ajustado, a idade perdeu sua significância na presença da FPP. Foram preditores significativos nos modelos simples e ajustados: desempenho cognitivo, circunferência da panturrilha, ser capaz de participar de atividades sociais e fazer compras e preparar refeições sozinho, desempenho no teste Timed Up and Go, e a facilidade para realizar atividades que exijam membros superiores. Conclusões: Concluímos que a FPP foi um importante preditor independente de sobrevida entre nonagenários e centenários, o que poderia ser melhorado por uma intervenção clínica.

ABSTRACT

Abstract Aim: To evaluate the chronic effects of resistance training on resting blood pressure, handgrip strength, gait speed, and Timed Up and Go test (TUG) in normotensive and hypertensive elderly individuals. Methods: Experimental study based on TREND. Hypertensive patients were diagnosed by an independent doctor. Before and after 12 weeks of progressive resistance training, we evaluated blood pressure, heart rate, body composition, Timed Up and Go test, gait speed, and handgrip strength. Results: Sample consisted of 41 participants divided into two groups (normotensive n = 28; hypertensive n = 13). We observed significant values in the reduction of blood pressure levels only in the group of hypertensive participants. In functionality outcomes, we observed significant values in all tests and both groups. Outcomes contemplate effect sizes ranging from small to moderate. Conclusion: Progressive resistance training lowers resting blood pressure levels, increases handgrip strength, and improves physical functional performance. Although the normotensive group did not show a reduction in blood pressure levels, an improvement was observed in the functional physical tests.

ABSTRACT

Introducción: Durante el envejecimiento se observa involución de algunos sistemas corporales. Entre estos cambios, los que afectan al sistema osteomuscular como la sarcopenia y la debilidad muscular, pueden alterar el desarrollo de actividades de la vida diaria, y por lo tanto, afectar la calidad de vida relacionada con la salud. Objetivo: Determinar la relación entre la fuerza de prensión manual y la calidad de vida relacionada con la salud en personas mayores. Métodos: Estudio descriptivo, correlacional. Evaluó 79 personas mayores (63 mujeres y 16 hombres) entre 65 y 78 años, de tres organizaciones sociales de la ciudad de Talca, Chile, seleccionados a través de un muestreo no probabilístico por conveniencia. Para medir la fuerza de prensión manual se utilizó un dinamómetro de mano y el cuestionario SF-36 fue usado para valorar la calidad de vida relacionada con la salud. Resultados: Se observaron relaciones significativas entre la fuerza de prensión manual y las dimensiones de la calidad de vida función física (p = 0,03; r = 0,76), dolor corporal (p = 0,01; r = 0,44) y salud general (p = 0,05; r = 0,48). Conclusiones: Existe relación entre la fuerza de prensión manual y tres dimensiones de la calidad de vida relacionada con la salud de personas mayores. Estos hallazgos corroboran la relevancia de evaluar la fuerza muscular en personas mayores como un marcador de salud y calidad de vida en estas(AU)


Introduction: During aging, involution of some body systems is observed. Among these changes, those that affect the musculoskeletal system such as sarcopenia and muscle weakness can alter the development of activities of daily life, and therefore affect health-related quality of life. Objective: to determine the relationship between hand grip strength and quality of life in elderly. Methods: Cross-sectional study. A total of 79 elderly (63 women and 13 men) between 65 and 78 years of age from three social organizations of Talca, Chile was included. A non-probabilistic convenience sample was used. To measure manual grip strength and the SF-36 questionnaire was used. Results: Significant relationships between hand grip strength and dimensions of quality of life, physical function (p = 0,03; r = 0,76), body pain (p = 0,01; r = 0,44) and general health (p = 0,05; r = 0,48) were observed. Conclusions: There is a relationship between hand grip strength and three measurements of quality of life in elderly. These findings corroborate the relevance of evaluating muscle strength in older people as a marker of health and quality of life in elderly(AU)

ABSTRACT

OBJECTIVE: To evaluate the relationship between respiratory muscle strength and grip strength in institutionalized and communitydwelling older adults. METHODS: This convenience sampled cross-sectional study had 64 voluntary participants with a good general health status and without limiting chronic diseases: 33 were institutionalized and 31 lived in the community. Maximal inspiratory pressure, maximal expiratory pressure, peak expiratory flow, grip strength, anthropometric data, and physical activity level were assessed. The data were subjected to descriptive analysis, Pearson's correlation test, and linear regression analysis. RESULTS: In the institutionalized group, there was no between respiratory variables and grip strength, but maximal expiratory pressure was the respiratory predictor most strongly associated with grip strength (p = 0.04). In the community-dwelling group, there was a correlation between maximal inspiratory pressure and grip strength (r = 0.54), maximal expiratory pressure and grip strength (r = 0.62), and peak expiratory flow and grip strength (r = 0.64); peak expiratory flow and maximal expiratory pressure were the respiratory predictors most strongly associated with grip strength (p < 0.05). In a joint group analysis, there was an association between maximal inspiratory pressure and grip strength (r = 0.40), maximal expiratory pressure and grip strength (r = 0.57), and peak expiratory flow and grip strength (r = 0.57); peak expiratory flow and maximal expiratory pressure were the respiratory predictors most strongly associated with grip strength (p < 0.05). CONCLUSIONS: Peak expiratory flow and maximal expiratory pressure seem to be good predictors of grip strength in community-dwelling older adults, but this relationship does not seem to be maintained in institutionalized patients, possibly because of a greater loss of respiratory function.


OBJETIVO: Avaliar a relação entre força muscular respiratória e força de preensão palmar em idosos institucionalizados e da comunidade. METODOLOGIA: Caracteriza-se por um estudo transversal com 64 voluntários, sendo 33 institucionalizados e 31 da comunidade. Avaliou-se a pressão inspiratória máxima, pressão expiratória máxima, pico de fluxo expiratório, força de preensão palmar, dados antropométricos e nível de atividade física.Os dados foram submetidos a uma análise descritiva, teste de correlação de Pearson e análise de regressão linear. RESULTADOS: No grupo de institucionalizados, não houve correlação entre as variáveis respiratórias e as de força de preensão palmar, porém o preditor respiratório mais fortemente associado à força de preensão palmar foi a pressão expiratória máxima (p = 0,04). No grupo da comunidade, verificou-se correlação entre pressão inspiratória máxima e força de preensão palmar (r = 0,54), pressão expiratória máxima e força de preensão palmar (r = 0,62), pico de fluxo expiratório e força de preensão palmar (r = 0,64), e o preditor respiratório mais fortemente associado à força de preensão palmar foi pico de fluxo expiratório e pressão expiratória máxima (p < 0,05). Na análise conjunta dos grupos, verificou-se associação entre pressão inspiratória máxima e força de preensão palmar (r = 0,40), pressão expiratória máxima e força de preensão palmar (r = 0,57), pico de fluxo expiratório e força de preensão palmar (r = 0,57), e o preditor respiratório mais fortemente associado à força de preensão palmar foi pico de fluxo expiratório e pressão expiratória máxima (p < 0,05). CONCLUSÕES: Em idosos da comunidade, o pico de fluxo expiratório e a pressão expiratória máxima parecem ser bons preditores da força de preensão palmar, enquanto, em institucionalizados, essa relação parece não se manter possivelmente por conta de maior acentuação de perda da função respiratória.

ABSTRACT

BACKGROUND@#There is little data on the association between the lower nutrition represented by serum albumin levels and related factors in a general population. The present study aimed to determine whether the albumin level positioned as some kind of biomarker with frailty measures, trace elements, and an inflammation marker.@*METHODS@#In 2018, we performed an epidemiological survey in 1368 subjects who resided in Tanushimaru, Japan, in which we examined the blood chemistry including albumin, trace elements, hormone levels, and carotid ultrasonography. Albumin levels were categorized into 4 groups (G1 [3.2-3.9 mg/dL], G2 [4.0-4.3 mg/dL], G3 [4.4-4.6 mg/dL], and G4 [4.7-5.3 mg/dL]). The participants underwent measurements of handgrip strength and were tested by asking to walk 5 m. Their cognitive functions were evaluated by the mini-mental state examination (MMSE).@*RESULTS@#Multiple stepwise regression analysis demonstrated that albumin levels were significantly and independently associated with age (inversely), systolic blood pressures, estimated glomerular filtration rate (eGFR), MMSE score, frailty measures (handgrip strength), an inflammation marker (high-sensitivity C-reactive protein), hormones (growth hormone (inversely) and insulin-like growth factor-1), and trace elements (calcium, magnesium, iron, and zinc), with a linear trend.@*CONCLUSIONS@#Lower albumin levels, even in the normal range, were found to be related factors of frailty measures, trace elements, and an inflammation marker in a general population.

ABSTRACT

SUMMARY: This study evaluated the effect of resistance exercise training (RET) on body composition and muscle strength in 16 older women during summer holidays (70.5 ± 8.4 years old; Range 60-87). Exercise sessions were carried out for twelve weeks, two sessions per week, with 60 minutes of exercise per session. We measured body mass index (BMI), fat mass percentage (FM%, by bioimpedance) and grip strength with a dynamometer before and after the intervention. The participants showed a significant increase in BMI (p<0.05), FM% (p<0.001), and a significant gain in grip strength (p<0.05). The RET program could be an important strategy for improving strength for older women, but we would suggest combining it with other interventions, such as aerobic exercises with gradually increasing intensity and nutrition interventions, in order to maintain a steady weight during holiday periods.


RESUMEN: Este estudio evaluó el efecto del entrenamien- to con ejercicios de resistencia (EER) sobre la composición corpo- ral y la fuerza muscular en 16 mujeres adultas mayores durante las vacaciones de verano (70,5 ± 8,4 años; Rango 60-87). Las sesio- nes de ejercicio se llevaron a cabo durante doce semanas, dos ve- ces por semana, con 60 minutos de ejercicio por sesión. Se evaluó el índice de masa corporal (IMC), el porcentaje de masa grasa (% MG, por bioimpedancia) y la fuerza de presión con un dinamómetro manual antes y después de la intervención. Las participantes mos- traron un aumento significativo en el IMC (p< 0,05), % de MG (p<0,001) y un incremento significativo en la fuerza prensil (p <0,05). El programa de EER podría ser una estrategia importante para mejorar la fuerza de mujeres adultas mayores durante el periodo estival. El EER se sugiere combinarlo con otras variables, como ejercicios aeróbicos con intensidad gradualmente creciente y una intervención nutricional, para mantener un peso constante durante los períodos de vacaciones.

ABSTRACT

Introducción: este artículo presenta la predicción de tres tipos de movimientos básicos de la mano mediante un algoritmo inteligente para extraer características imprescindibles para el reconocimiento de patrones de movimiento a partir del análisis de señales electromiográficas superficiales adquiridas con el dispositivo Myo. Objetivo: reconocer y predecir patrones básicos de movimiento de la articulación del brazo utilizando electromiografía de superficie para aplicarlo sobre un prototipo de prótesis. Métodos: se tomaron datos de 13 estudiantes de 22 y 23 años de la Universidad Politécnica Salesiana, cada uno de los cuales ejecutó tres tipos de agarre: cilíndrico, pinza y pinza planar. Se trabajó con una frecuencia de 10 Hz y se tomaron 5 muestras por tipo de agarre durante 60 segundos. Para el análisis estadístico de los datos se utilizó la herramienta Anova, estableciendo un valor de significancia mayor a 0,65. Resultados: En ciertos voluntarios hay una mayor reacción en el electrodo 1 debido a que su antebrazo es mayor. El tiempo de respuesta para el reconocimiento varía dependiendo del número de variables que se tenga que comparar. Cuando se analiza un solo movimiento es de 2,6 segundos, en cambio, cuando se analizan los 3 movimientos el tiempo de respuesta incrementa a 7,8 segundos por la cantidad de electrodos que se quieran analizar. Conclusiones: la respuesta del sistema propuesto empieza a ser más lenta a medida que se analizan más movimientos a la vez y por tanto, es menos efectiva. El tiempo de ejecución y respuesta de nuestro sistema, en comparación al estado del arte, es más alto, debido a que se utilizan menos métodos de caracterización de la señal. Adicionalemtne, una limitante del proyecto es la frecuencia de muestreo del dispositivo Myo (200Hz)(AU)


Introduction: the paper presents the prediction of three basic hand movement types by means of a smart algorithm to draw characteristics indispensable for identification of movement patterns based on the analysis of surface electromyographic signals obtained with the Myo device. Objective: recognize and predict basic movement patterns of the arm joint using surface electromyography with a view to applying them over a prosthesis prototype. Methods: data were taken from 13 students aged 22 and 23 years from the Salesian Polytechnic University, each of whom performed three types of grasp: cylindrical, pincer and palmar pincer. A 10 Hz frequency was used and 5 samples were taken of each grasp type during 60 seconds. Statistical analysis was performed with the tool ANOVA, establishing a significance value > 0.65. Results: in certain volunteers a greater reaction was observed in electrode 1, due to their larger forearms. Response time for identification varies with the number of variables to be compared. When only one movement is analyzed, response time is 2.6 seconds, but when the three movements are examined it rises to 7.8 seconds by the number of electrodes intended to be studied. Conclusions: the response of the system proposed starts to slow down as more movements are analyzed simultaneously, which makes it less effective. The performance and response time of our system is higher than in state-of-the-art systems, since fewer signal characterization methods are used. On the other hand, a limitation of the project is the sampling frequency of the Myo device (200 Hz)(AU)

ABSTRACT

Background: Moderate isometric handgrip exercise is an effective tool in the management of systemic hypertension. Aim: To evaluate the effectiveness of a high intensity isometric handgrip exercise protocol for the reduction of blood pressure in older people with pre or stage-1 hypertension. Material and Methods: Twenty-three participants aged 73.8 ± 6.6 years (range 61-90) completed eight weeks of high intensity isometric handgrip training 2 times per week, performing 32 contractions maintained for 5 seconds, with breaks of 5 seconds. Blood pressure (BP) was measured at baseline and at the end of the intervention. Results: Systolic blood pressure decreased from 141 ± 11 to 127 ± 10 mmHg (p < 0.01). The decrease in diastolic blood pressure was from 79 ± 7 to 74 ± 6 mmHg (p < 0.01). Conclusions: A blood pressure reduction was recorded in these participants after a period of high intensity isometric handgrip exercise.

ABSTRACT

ABSTRACT Objectives : to investigate the impact of oncological surgical procedures on the muscle function of patients with and without nutritional risk. Methods: cross-sectional study conducted with cancer patients undergoing major operations between July 2018 to March 2019 in Cuiabá, Mato Grosso, Brazil. Patients were assessed preoperatively for the nutritional risk by the Nutricional Risk Screening-2002, and handgrip strength (FPP) was assessed both on the pre- and 2nd and 5th postoperative days (PO). Results: 92 patients were evaluated, of whom 55.4% were men and 44.6% women, with a mean age (SD) of 64 (10.81) for patients at risk and 51 (12.99) for patients without nutritional risk. The preoperative nutritional risk evaluation indicated that 34.8% of the patients had no risk and 65.2% had a nutritional risk. The FPP was lower (p = 0.008) in the group with nutritional risk in the preoperative period. In both groups, there was a significant drop in FPP on the 2nd PO day. The preoperative FPP compared with the 2nd PO FPP was more pronounced in patients without nutritional risk (p = 0.039). Patients with nutritional risk had a longer hospital stay (p = 0.049). Conclusion: surgical trauma causes loss of muscle function in the early PO. Patients without nutritional risk have a more significant decrease in muscle strength after surgical oncological procedures than those with nutritional risk. These results may infer the need to implement pre-habilitation in all patients who will undergo major oncological procedures.


RESUMO Objetivo: investigar o impacto de procedimentos cirúrgicos oncológicos na função muscular de pacientes com e sem risco nutricional. Métodos: estudo observacional realizado com pacientes oncológicos candidatos a operações de grande porte entre julho de 2018 a março de 2019 em Cuiabá, Mato Grosso, Brasil. Os pacientes foram avaliados no pré-operatório quanto ao risco nutricional pela Nutricional Risk Screening-2002 e avaliou-se a força de preensão palmar (FPP) tanto no pré- quanto no 2º e 5º dia de pós-operatório (PO). Resultados: Foram avaliados 92 pacientes, dos quais 55,4% eram homens e 44,6% mulheres, com média (DP) de idade de 64 (10,81) para pacientes com risco e 51 (12,99) para pacientes sem risco nutricional. A avaliação nutricional pré-operatória mostrou que 34,8% dos pacientes não tinham risco e 65,2% apresentavam risco nutricional. A FPP foi menor (p=0,008) no grupo com risco nutricional no pré-operatório. Em ambos os grupos houve queda significativa da FPP no 2º dia de PO. A queda da FPP do pré-operatório para o 2º dia de PO foi mais pronunciada em pacientes sem risco nutricional (p=0,039). Pacientes com risco nutricional apresentaram maior tempo de internação (p=0,049). Conclusão: O trauma cirúrgico acarreta perda da função muscular no PO precoce. Pacientes sem risco nutricional apresentam queda da força muscular mais expressiva após procedimentos cirúrgicos oncológicos do que aqueles com risco nutricional. Esses resultados servem como argumento bastante forte para a implementação da Pré-habilitação em todos os pacientes candidatos a operações oncológicas de grande porte.

ABSTRACT

Objetivos: Avaliar a força de preensão palmar de mulheres com hipermobilidade articular, comparando-as com as sem hipermobilidade articular, relacionando idade, dominância manual e comportamento da força de preensão palmar ao longo das mensurações. Métodos: Trata-se de estudo transversal de caráter analítico. A amostra foi composta por 68 mulheres, das quais 42 formaram o Grupo Hipermobilidade Articular e 26 o Grupo Controle. Como instrumento de coleta, foi utilizado o dinamômetro Jamar®, tendo sido seguido o protocolo recomendado pela American Sociecity of Hand Therapists (ASHT). A análise estatística foi realizada utilizando o software BioEstat 5.0 e a análise de variância, para avaliar a significância das médias, seguido dos testes de Tukey e t de Student independente para as variáveis antropométricas, idade e força manual bilateral, considerando índice de significância de 95%. Resultados: Houve predomínio da força de preensão palmar da mão direita em relação à esquerda em ambos os grupos. Indivíduos portadores de hipermobilidade articular possuíam menor força em ambas as mãos quando comparados ao Grupo Controle. A força manual bilateral do Grupo Controle foi maior naqueles com idade igual e superior a 21 anos em relação aos indivíduos com idade igual e menor a 20 anos. Ainda, indivíduos hipermóveis com idade igual e menor a 20 anos possuíam menor força quando comparados ao Grupo Controle com idade igual e maior a 21 anos em ambas as mãos. Conclusão: Considerando os resultados concebidos por este estudo, sugere-se que há correlação entre força de preensão manual e hipermobilidade articular.


Objective: To evaluate handgrip strength in women with joint hypermobility, comparing them with those who do not have joint hypermobility, relating age, hand dominance and behavior of the hand grip strength throughout the measurements. Methods: This is an analytical cross-sectional study. The sample consisted of 68 women, of which 42 formed the group Joint Hypermobility, and 26 the Control Group. As a collection instrument, the Jamar® dynamometer was used, and the protocol recommended by American Sociecity of Hand Therapists ­ ASHT was followed. Statistical analysis was performed using the software BioEstat 5.0, and the analysis of variance, to evaluate the significance of the means, followed by the Tukey e t-student tests, independent for the anthropometric variables, age and bilateral hand strength, considering a significance index of 95%. Results: There was a predominance of hand grip strength of the right hand in relation to the left in both groups. Individuals with joint hypermobility have less strength in both hands when compared to the control group. Bilateral hand grip strength of the Control Group is greater in those aged 21 years and over, compared to individuals aged less than 20 years. Moreover, hypermobile individuals aged less than 20 years had lower strength when compared to the Control Group with age equal to and greater than 21 years in both hands. Conclusion: considering the results conceived by this study, a correlation between hand grip strength and joint hypermobility is suggested

ABSTRACT

INTRODUÇÃO: As alterações musculares que acompanham o envelhecimento, traduzidas numa diminuição quer na massa quer na capacidade de trabalho da musculatura, condicionam diminuições na força e resistência ao esforço no idoso. OBJETIVO: Correlacionar a perda de capacidade de trabalho muscular com as possíveis alterações ventilatórias derivadas dessa perda em idosos. MÉTODOS: Estudo transversal com 18 adultos voluntários com idade superior a 65 anos (13 do sexo feminino e cinco do sexo masculino), incluídos no Projeto AGA@4life. Todos os participantes realizaram provas funcionais respiratórias com espirômetro Flowhandy ZAN 100, e foi-lhes avaliada a força de preensão com um dinamômetro apropriado. Avaliaram-se ainda a composição corporal por bioimpedância e o perfil nutricional. RESULTADOS: Observou-se associação significativa entre a percentagem de massa magra e diversos parâmetros espirométricos, nomeadamente o volume expiratório máximo no primeiro segundo (VEMS), a capacidade vital forçada (CVF), o débito expiratório máximo a 25% da CVF (DEM25), o débito expiratório máximo a 50% da CVF (DEM50), o débito expiratório máximo entre 25 e 75% da capacidade vital forçada (DEM25/75) e o débito expiratório máximo (PEF). Também, a autoeficácia no exercício se associou significativamente com VEMS, CVF, DEM25, DEM50, DEM75 e DEM25/75 e PEF. Constatou-se ainda correlação significativa e positiva da percentagem de massa magra com a força de preensão. CONCLUSÕES: Os resultados demonstram associação entre a função ventilatória e parâmetros funcionais e clínicos característicos da sarcopenia, sugerindo a partilha de mecanismos fisiopatológicos na limitação observada com o agravamento desses parâmetros.


INTRODUCTION: Age-related muscle changes, translated into a decrease both in muscle imass and functionality, are determinants of a decrease in strength and resistance to exercise in older adults. OBJECTIVE: To correlate the loss of muscle mass and functionality with the respiratory function in older adults. METHODS: Cross-sectional study including 18 volunteers with age above 65 years (13 women and 5 men) included in the AGA@4life Project. All participants performed functional respiratory tests with an Flowhandy ZAN 100 spirometer, and handgrip strength was assessed with an appropriate dynamometer. Nutritional profile was assessed and body composition was evaluated via bioimpedance. RESULTS: There was a significant association between the percentage of lean mass and several spirometric parameters, namely the FEV1, FVC, PEF25, PEF50, PEF25/75 and PEF. Significant associations were also found with the self-efficacy for exercise and the same respiratory parameters. A significant and positive correlation was observed between the percentage of lean mass and handgrip strength. CONCLUSIONS: The results show an association between respiratory function and functional and clinical parameters characteristic of sarcopenia, suggesting common pathophysiological mechanisms in the limitation observed with the worsening of these parameters.

ABSTRACT

OBJETIVO: Estudar a possível relação entre qualidade de vida e características sociodemográficas, antropométricas, funcionais e de atividade física em idosos da Estratégia Saúde da Família de Porto Alegre (RS). MÉTODOS: Estudo transversal e analítico com idosos (≥ 60 anos). Os dados foram coletados de forma prospectiva em amostra aleatória de 30 unidades de saúde. As variáveis pesquisadas foram: sociodemográficas (idade, estado civil, escolaridade); antropométricas (peso, altura, índice de massa corporal); e funcionais (velocidade de marcha, força de preensão manual, teste senta/levanta). Foi aplicada a escala de qualidade de vida de Flanagan e o questionário de Minnesota de atividade física e de lazer para o nível de atividade física. Analisaram-se os dados utilizando regressão logística pelo método backward conditional. RESULTADOS: Entre os 577 idosos avaliados (68,5 ± 6,4 anos; 63,7% mulheres), a qualidade de vida de 87% foi classificada como alta. No modelo multivariado inicial (saturado), foram consideradas variáveis preditoras de qualidade de vida: sexo, convivência marital, tempo gasto para caminhar 10 m, escore do teste senta/levanta, força de preensão manual e atividade física moderada, intensa e total. O modelo final (seis etapas) foi composto de quatro variáveis: conviver maritalmente, maior escore do teste senta/levanta, maior força de preensão manual e prática de atividade física intensa. CONCLUSÃO: Conforme observado, a alta qualidade de vida relacionou-se a idosos que convivem maritalmente, apresentam maior força de membros superiores e inferiores e despendem mais tempo na prática de atividade física intensa.


OBJECTIVE: To study the possible relation between quality of life and sociodemographic, anthropometric, functional and physical activity characteristics in older users of the Family Health Strategy in Porto Alegre-RS. METHODS: Cross-sectional and analytical study with older subjects (≥ 60 years). Data were prospectively collected in a random sample of 30 health units. The following variables were analyzed: sociodemographic (age, marital status, education); anthropometric (weight, height, body mass index); functional (walking speed, handgrip strength, Sit/Stand test). The Flanagan Quality of Life Scale and the Minnesota Physical Activity and Leisure Questionnaire (level of physical activity) were applied. Logistic Regression (Backward Conditional Method) was used for data analysis. RESULTS: Among the 577 older subjects evaluated (68.5 ± 6.4 years; 63.7% women), the majority (87%) presented high quality of life. In the initial multivariate (saturated) model, the following variables were considered as predictors of quality of life: gender, marital coexistence, time spent walking 10 m, higher Sit/Stand test score, handgrip strength, moderate, intense and total physical activity. The final model (6 steps) consisted of four variables: cohabitation, higher Sit/Stand test score, higher handgrip strength and engagement in intense physical activity. CONCLUSION: As observed, a high quality of life was related to older people who lived with a partner, presented higher upper and lower limb strength, and spent more time in the practice of intense physical activity.

ABSTRACT

In elite athletes, the palmaris longus (PL) presence has a potential contribution to hand strength, smaller reaction time, better shooting speed and power. The aim of this study was to investigate the prevalence of PL in elite competitive artistic gymnasts and its impact on grip strength compared to a control group of moderately active non-athletes. This prospective study included 370 subjects divided in two groups (170 elite artistic gymnasts and 200 moderately active non-athletes, students of medicine). The study consisted of two clinical sets of examination: a search for the clinical presence of PL was initially conducted followed by the assessment of maximal grip strength. Standard and six additional tests were performed to confirm PL tendon absence. Maximal grip strength was measured bilaterally with an electronic hand dynamometer. Bilateral absence was more common than unilateral, predominately noted on left side in both study groups. Unilateral PL absence was correlated to decreased grip strength in students, while the opposite was found in gymnasts. The mean value of grip strength in some age groups was higher on the side where the PL was absent. The results of our study show that the presence of the PL doesn`t affect the hand grip strength in gymnasts. Due to the low incidence of unilateral PL absence, further large-sampled research is warranted to assess PL contribution to hand grip strength and to other hand functions that could be of significant importance for athletes and non-athletes.


La presencia del músculo palmar largo (MPL) en atletas de élite tiene el potencial de aportar mayor fuerza a la mano, un tiempo de reacción menor, mejor velocidad de tiro y potencia. El objetivo de este estudio fue investigar la prevalencia de MPL en las gimnastas artísticas competitivas de élite y su impacto en la fuerza de agarre en comparación con un grupo control de no atletas moderadamente activos. El estudio incluyó 370 sujetos divididos en dos grupos (170 gimnastas artísticas de élite y 200 no atletas moderadamente activos, estudiantes de medicina). El estudio consistió en dos series clínicas de examen: inicialmente se realizó una búsqueda de la presencia clínica de MPL, seguido de la evaluación de la fuerza máxima de agarre. Se realizaron pruebas estándar y seis pruebas adicionales para confirmar la ausencia del tendón del MPL. La máxima fuerza de agarre se midió bilateralmente con un dinamómetro de mano electrónico. La ausencia bilateral fue más común que unilateral, predominantemente observada en el lado izquierdo en ambos grupos de estudio. La ausencia unilateral de MPL se correlacionó con una menor fuerza de agarre en los estudiantes, mientras que en gimnastas se encontró lo contrario. El valor medio de la fuerza de agarre en algunos grupos de edad fue mayor en el lado donde el MPL estaba ausente. Los resultados de nuestro estudio muestran que la presencia de MPL no afecta la fuerza de agarre de la mano en gimnastas. Debido a la baja incidencia de ausencia unilateral de MPL, se justifica una investigación adicional de gran tamaño para evaluar la contribución de MPL a la fuerza de agarre de la mano y otras funciones de la mano que podrían ser de gran importancia para los atletas y no atletas.

ABSTRACT

Resumo O objetivo foi estabelecer pontos de corte por sexo para a avaliação dos componentes de fragilidade de idosos residentes na comunidade. Estudo transversal de base populacional, com 555 idosos adscritos às Estratégias Saúde da Família; selecionados por amostragem estratificada proporcional. Foram avaliados dados socioeconômicos e os componentes do fenótipo de fragilidade. Quanto à classificação de fragilidade, 17,7% dos idosos eram frágeis, 45,4% pré-frágeis e 36,9% não frágeis. Os pontos de corte estabelecidos para essa população foram: para força de preensão palmar, em homens e mulheres respectivamente com 0 < IMC < 23 foi 20,30 e 13,36; 23 < IMC < 28 foi 23,52 e 16,12; 28 < IMC < 30 foi 22,04 e 15,17; e 30 < IMC < 50 foi 25,42 e 17,51; para velocidade da marcha, para homens com 0 < altura < 1,67 foi ≥ 7,08s e altura > 1,68 foi 6,46s; e mulheres com 0 < altura < 1,55 foi 7,60s e com altura > 1,56 foi 7,45s; e gasto metabólico semanal para homens foi de 1603,96 e para mulheres foi de 2182,25. Os resultados poderão apoiar as equipes de saúde para avaliar e estratificar o risco de fragilidade dos idosos na comunidade e subsidiar o planejamento de ações de promoção, prevenção e recuperação da capacidade funcional.


Abstract The objective was to establish cutoff points per gender for the evaluation of the fragility components of elderly residents in the community. It involved a cross-sectional population-based study with 555 elderly people enrolled in the Family Health Strategies selected by proportional stratified sampling. Socioeconomic data and the components of the fragility phenotype were evaluated. Regarding the classification of fragility, 17.7% of the elderly were fragile, 45.4% pre-fragile and 36,9% non-fragile. The cutoff points established for this population were: for hand grip strength, in men and women respectively with 0 < BMI < 23 was 20.30 and 13.36; 23 < BMI < 28 was 23.52 and 16.12; 28 < BMI < 30 was 22.04 and 15.17; And 30 < BMI < 50 was 25.42 and 17.51; For gait speed, for men with < height < 1.67 was ≥ 7.08s and height > 1.68 was 6.46s; And women with < height < 1.55 were 7.60s and with height > 1.56 were 7.45s; And weekly metabolic expenditure for men was 1,603.96 and for women it was 2,182.25. The results may support health teams to assess and stratify the risk of frailty of the elderly in the community and to subsidize the planning of actions to promote, prevent and recover functional capacity.

ABSTRACT

Resumo O objetivo deste artigo é verificar a influência do desempenho físico na mortalidade, funcionalidade e satisfação com a vida de idosos. Foi realizado o seguimento de 900 idosos brasileiros não hospitalizados entre os anos de 2008 e 2016, no qual foram incluídos na análise de sobrevivência 154 óbitos por causas naturais. Os piores desempenhos de força de preensão manual (R.R. = 1,60; IC 95% = 1,15-2,23; p = 0,005) e de velocidade usual de marcha (R.R. = 1,82; IC 95% = 1,30-2,55; p < 0,001) associaram-se com o aumento do risco de mortalidade. A idade foi um fator de confusão para a força (R.R. = 1,06; IC 95% = 1,03-1,09; p < 0,001) e a artrite reumatoide foi um fator de confusão para a velocidade (R.R. = 2,02; IC 95% = 1,36-3,01; p < 0,001). Os idosos com bom desempenho físico faziam mais atividades instrumentais e avançadas da vida diária, e o bom desempenho de marcha apresentou efeito significativo na satisfação com a vida (F = 6,87; p = 0,009). O bom desempenho físico parece ser fundamental para a longevidade e para a realização de tarefas do cotidiano. Além disso, a boa mobilidade pode afetar mecanismos relacionados à satisfação com a vida.


Abstract Objective: To verify the influence of physical performance on elderly mortality, functionality and life satisfaction. Materials and methods: A follow-up was performed on 900 Brazilian non-hospitalized elderly in the period 2008-2016, in which 154 deaths from natural causes were included in the survival analysis. Results: the worst grip strength (RR = 1.60; CI 95% = 1.15-2.23, p = 0.005) and gait speed (RR = 1.82; CI 95% = 1.30-2.55, p < 0.001) performances were associated with increased mortality risk. Age was a confounding factor for strength (RR = 1.06; CI 95% = 1.03-1.09, p < 0.001) and rheumatoid arthritis was a confounding factor for speed (RR = 2.02; CI 95% = 1.36-3.01, p < 0.001). The elderly with good physical performance realized more instrumental and advanced activities of daily living, and good gait performance had a significant effect on life satisfaction (F = 6.87, p = 0.009). Conclusions: good physical performance seems to be fundamental for longevity and for accomplishing daily tasks. Furthermore, good mobility can affect life satisfaction-related mechanisms.

ABSTRACT

ABSTRACT Duchenne muscular dystrophy (DMD) is a disease characterized by progressive loss of muscle fiber, gradually from proximal to distal. Although a few studies have investigated hand grip strength in non-ambulatory DMD patients, a lack of literature was found determining its relationship with functional capacity. Objective: The aim of this study was to determine the associations between hand grip strength and functional measures in non-ambulatory children with DMD. Methods: Hand grip strength was evaluated using a dynamometer in children with DMD. The children with DMD were evaluated with the Turkish version of the Egen Klassifikation Scale Version 2 (EK2) for global functional capacity, the Performance of Upper Limb (PUL) for upper limb functional performance and the ABILHAND-Kids for hand ability. Results: The mean age of 38 DMD children was 12.02 ± 1.99 years. Dominant hand grip strength of the children with DMD was higher than the non-dominant hand (p < 0.05). The EK2 was 13.02 ± 5.50, PUL was 49.86 ± 14.34 and ABILHAND-Kids was 26.81 ± 7.59. Hand grip strength was found to be correlated with the EK2 (p < 0.05). Conclusions: It is known that measuring functional ability and strength in very weak children with DMD has been difficult and complex for therapists/clinicians in the clinical environment. Although there is a moderate correlation, hand grip strength may be used in clinical practice as a practical assessment tool to have an immediate insight into the global functional capacity in non-ambulatory DMD children.


RESUMO A distrofia muscular de Duchenne (DMD) é uma doença caracterizada por perda progressiva da fibra muscular, gradualmente de proximal a distal. Embora poucos estudos tenham investigado a força de preensão manual em pacientes com DMD não ambulatoriais, foi observada uma falta de literatura para determinar suas relações com a capacidade funcional. Objetivo: O objetivo deste estudo foi determinar as associações entre força de preensão manual e medidas funcionais em crianças não ambulatoriais com DMD. Métodos: A força de preensão manual foi avaliada com dinamômetro em crianças com DMD. As crianças com DMD foram avaliadas com a versão turca da Egen Klassifikation Scale Versão 2 (EK2) para capacidade funcional global, desempenho do membro superior (PUL) para desempenho funcional do membro superior e ABILHAND-Kids para a habilidade manual. Resultados: A idade média de trinta e oito crianças com DMD foi de 12,02 ± 1,99. A força de preensão manual dominante das crianças com DMD foi maior que a da mão não dominante (p < 0,05). A EK2 foi calculada em 13,02 ± 5,50, PUL em 49,86 ± 14,34 e ABILHAND-Kids em 26,81 ± 7,59. A força de preensão manual foi correlacionada com a EK2 (p < 0,05). Conclusões: Sabe-se que medir a capacidade funcional e força em crianças muito fracas com DMD tem sido difícil e complexo para terapeutas / clínicos em ambiente clínico. Embora exista uma correlação moderada, a força de preensão manual pode ser usada na prática clínica como uma ferramenta de avaliação prática para obter imediatamente uma percepção da capacidade funcional global em crianças com DMD não ambulatoriais.

ABSTRACT

Background: A low hand grip strength is a prognostic factor both in healthy people and hospitalized subjects. Local normal hand grip strength values are needed to define cutoff points of abnormality. Aim: To measure handgrip strength in Chilean people aged 20 to 70 years and propose normal values for healthy people in this age range. Material and Methods: Handgrip strength was measured using a JAMAR hydraulic dynamometer in 436 males and 465 females aged 20 to 70 years and who were free of disease. They were recruited from waiting rooms in several public and private hospitals and outpatient clinics, under self-evaluation of inclusion criteria. Results: The variability of the handgrip strength in women was smaller in than men. Tables containing handgrip strength values by age and sex and the ranges between three standard deviations were prepared. Conclusions: This study contributes with normal handgrip strength values in Chile to be used for the diagnosis and management of various conditions, such sarcopenia, obesity, oncological patients, Intensive Care Unit acquired weakness (ICU-aw) and weaning of mechanical ventilation.
