Influence of lower limb isokinetic muscle strength and power on the occurrence of falls in community-dwelling older adults: A longitudinal study.

INTRODUCTION: Previous studies have highlighted the association between lower limb muscle strength and falls in older adults. However, a comprehensive understanding of the specific influence of each lower limb muscle group on fall occurrences remains lacking. OBJECTIVE: This study aimed to investigate the impact of knee, ankle, and hip muscle strength and power on falls in older adults, with the goal of identifying which muscle groups are more predictive of fall risk in this population. METHODS: This longitudinal observational study enrolled 94 community-dwelling older adults. Muscle strength and power of the ankle's plantiflexors and dorsiflexors, knee flexors and extensors, and hip flexors, extensors, adductors, and abductors were assessed using a Biodex System 4 Pro® isokinetic dynamometer. Fall occurrences were monitored through monthly telephone contact over a year. RESULTS: Participants, with a median age of 69 years (range 64-74), included 67% women, and 63.8% reported a sedentary lifestyle. Among them, 45,7% of older adults were classified as fallers. Comparative analyses revealed that non-fallers displayed significantly superior isokinetic muscle strength in the hip abductors and adductors, along with higher muscle power in the hip abductors, hip flexors, and knee flexors compared to fallers. Multivariate logistic regression analysis indicated that a 1 Nm/Kg increase in hip abductor strength reduced the chance of a fall by 86.3%, and a 1 Watt increase in hip flexor power reduced the chance of a fall by 3.6%. CONCLUSION: The findings indicate that hip abductor strength and hip flexor power can be considered protective factors against falls in independent older adults in the community. These findings may contribute to developing effective fall-prevention strategies for this population.

Is prehospital physical performance a predictor of functional capacity decline at discharge in hospitalized Brazilian older adults?

BACKGROUND: Hospitalization contributes to functional decline in older adults. OBJECTIVE: To assess the relationship between physical performance on admission and functional capacity and functional capacity decline at discharge, and to investigate tools capable of predicting this decline. METHODS: Prospective longitudinal study with 75 older adults admitted to a public hospital between July 2021 and February 2022. The independent variable was physical performance evaluated on admission by handgrip strength (HGS) and the Short Physical Performance Battery (SPPB). The dependent variables were functional capacity for basic activities of daily living (BADLs) and instrumental activities of daily living (IADLs) and their decline between admission and discharge. Statistical analyses were performed using linear and logistic regression and ROC curves. RESULTS: The median time between admission and participant assessment was 1 day (IQR=1-2 days). Median hospitalization time was 18 days (IQR= 7.5-30 days). Functional capacity for BADLs and IADLs declined in 39% and 79% of the participants, respectively. Performance in HGS and the SPPB at baseline, in adjusted models, explained 29.3 to 35.3% of functional capacity at discharge. One additional point in the SPPB decreased the risk of functional capacity decline for BADLs by 20.9% (OR=0.79, 95% CI: 0.68, 0.91). The AUC values for the SPPB (AUC=0.67) and HGS (AUC=0.65) were significant in identifying functional decline for BADLs, but not IADLs. CONCLUSION: In Brazilian older adults, physical performance on admission was related to functional capacity and its decline at discharge. Physical performance on admission is predictive of functional decline at discharge.

Urinary symptoms, falls and fear of falling in older people with cognitive impairment / Sintomas urinários, quedas e medo de cair em idosos com comprometimento cognitivo

Abstract Introduction: Among geriatric syndromes, cognitive impairment, urinary incontinence, nocturia, and falls stand out. Older adults with urinary incontinence are more prone to falls and exhibit fear of falling. Objective: To investigate the frequency of urinary incontinence and nocturia and evaluate the association of these variables with falls and fear of falling in older individuals with cognitive impairment. Methods: Cross-sectional study with older adults referred from Basic Health Units with cognitive impairment evaluated between 2019 and 2021. Information on urinary incontinence, nocturia, history of falls, and fear of falling provided by the participants and their caregivers was collected. Data were analyzed using Chi-square tests and univariate logistic regressions. Results: Data from 89 older adults were analyzed, of whom 58.4% had urinary incontinence, 28.1% had nocturia, 67.4% reported fear of falling, and 41.6% reported falls in the last six months. The group with urinary incontinence [χ2(1) = 5.147; p = 0.023] and the group with nocturia [χ2(1) = 4.353; p = 0.037] had significantly higher frequencies of fear of falling. No differences in the frequencies of history of falls were observed between individuals with and without urinary incontinence or nocturia (p > 0.05). Fear of falling was associated with urinary incontinence (OR = 2.833; 95% CI 1.137 - 7.062) and nocturia (OR = 3.365; 95% CI 1.033 - 10.966). Conclusion: Older adults with cognitive impairment have a high frequency of urinary incontinence, nocturia, falls, and fear of falling. Furthermore, there is an association between urinary incontinence, nocturia and fear of falling in this population.

O grupo com incontinência urinária [2(1) = 5,147; p = 0,023] e o grupo com noctúria [χ2(1) = 4,353; p = 0,037] apresentaram frequências significativamente maiores de medo de cair. Não foram observadas diferenças das frequências de histórico de quedas entre os indivíduos com e sem incontinência ou noctúria (p > 0,05). O medo de cair mostrouse associado à incontinência (OR = 2,833; IC95% 1,137 - 7,062) e à noctúria (OR = 3,365; IC 95% 1,033 - 10,966). Conclusão: Idosos com comprometimento cognitivo apresentam alta frequência de incontinência urinária, noctúria, quedas e medo de cair. Ademais, há associação da incontinência urinária e da noctúria com o medo de cair nessa população.

Factors predicting hospital admission and death in older adults with cognitive impairment: a longitudinal study / Factores predictivos de hospitalización y muerte en ancianos con deterioro cognitivo: un estudio longitudinal / Fatores preditores de hospitalização e óbito em idosos com comprometimento cognitivo: um estudo longitudinal

ABSTRACT Objective: to identify sociodemographic factors, clinical conditions and sarcopenia parameters that predict hospital admission and death in older adults with cognitive impairment. Method: this is a longitudinal observational study carried out with 170 older adults with cognitive impairment assessed between 2019 and 2021. Predictor variables were sociodemographic characteristics, clinical conditions and sarcopenia parameters. Sarcopenia was operationalized through handgrip muscle strength (dynamometry), muscle mass (calf circumference) and the Timed Up and Go test. Occurrence of hospital admission and death within one year after assessment of older adults were the predicted variables. Analyzes were carried out using descriptive statistics, independent Student' t-test, Mann-Whitney U test, chi-square test and univariate logistic regression. Results: most participants were female (±77.57 years old), with low education, sedentary, 15.9% with sarcopenia and 13% with a history of hospital admission. It was identified that education level had an effect on occurrence of hospital admission (U=1,423.5, p=0.027) and death (U=647.0, p=0.025) within one-year follow-up. Furthermore, there is an association between history of hospital admission in the last 6 months and occurrence of hospital admission [χ2(1)=4.729; p=0.030] and death [χ2(1)=3.919; p=0.048] within one year follow-up. It was identified that history of hospital admission in the last 6 months was associated with occurrence of hospital admission within one-year follow-up (OR=2.963; 95%CI 1.076-8.165, p=0.036). Conclusion: history of hospital admission in the last six months is associated with occurrence of hospital admission over a year in older adults with cognitive impairment.

Método: estudio observacional longitudinal realizado con 170 personas mayores con deterioro cognitivo evaluados entre 2019 y 2021. Las variables predictoras fueron las características sociodemográficas, las condiciones clínicas y los parámetros de sarcopenia. La sarcopenia se puso en práctica mediante la fuerza de los músculos de prensión manual (dinamometría), la masa muscular (circunferencia de la pantorrilla) y la prueba Timed Up and Go. La ocurrencia de hospitalización y muerte dentro del año posterior a la evaluación del anciano configuró las variables predichas. Los análisis se realizaron mediante estadística descriptiva las pruebas t de Student independiente, U de Mann-Whitney, chi-cuadrado y regresión logística univariada. Resultados: la mayoría de los participantes fueron del sexo femenino (±77,57 años), con bajo nivel educativo, sedentarios, el 15,9% con sarcopenia y el 13% con antecedentes de hospitalización. Se identificó que el nivel de escolaridad tuvo efecto en la ocurrencia de hospitalización (U=1.423,5, p=0,027) y muerte (U=647,0, p=0,025) al año de seguimiento. Además, existe asociación entre el antecedente de hospitalización en los últimos 6 meses y la ocurrencia de hospitalización [χ2(1)=4,729; p=0,030] y muerte [χ2(1)=3,919; p=0,048] al año de seguimiento. Se identificó que el antecedente de hospitalización en los últimos 6 meses se asoció con la ocurrencia de hospitalización en un año de seguimiento (OR=2,963; IC95% 1,076-8,165, p=0,036). Conclusión: un antecedente de hospitalización en los últimos seis meses se asocia con la ocurrencia de hospitalización mayor a un año en personas mayores con deterioro cognitivo.

Método: estudo observacional longitudinal realizado com 170 idosos com comprometimento cognitivo avaliados entre 2019 e 2021. As variáveis preditoras foram características sociodemográficas, condições clínicas e parâmetros de sarcopenia. A sarcopenia foi operacionalizada por meio da força muscular de preensão palmar (dinamometria), da massa muscular (circunferência da panturrilha) e do teste Timed Up and Go. A ocorrência de hospitalização e óbito até um ano após a avaliação do idoso configuraram as variáveis preditas. Procedeu-se análises por estatística descritiva, testes t-student independente, U Mann Whitney, Qui-Quadrado e de regressão logística univariada. Resultados: a maioria dos participantes era do sexo feminino (±77,57 anos), de baixa escolaridade, sedentários, 15,9% com sarcopenia e 13% com histórico de internação. Foi identificado que o nível de escolaridade teve efeito sobre a ocorrência de hospitalização (U=1423,5, p=0,027) e de óbito (U=647,0, p=0,025) no seguimento de um ano. Além disso, há associação do histórico de internação nos últimos 6 meses com a ocorrência de hospitalização [χ2(1)=4,729; p=0,030] e de óbito [χ2(1)=3,919; p=0,048] no seguimento de um ano. Identificou-se que o histórico de internação nos últimos 6 meses associou-se com a ocorrência de hospitalização em um ano de seguimento (OR=2,963; IC95% 1,076-8,165, p=0,036). Conclusão: o histórico de internação nos últimos seis meses está associado à ocorrência de hospitalização ao longo de um ano em idosos com comprometimento cognitivo.

Are dose-response relationships of resistance training reliable to improve functional performance in frail and pre-frail older adults? A systematic review with meta-analysis and meta-regression of randomized controlled trials.

This systematic review with meta-analyses investigates the impact of resistance training (RT), using meta-regressions, on functional performance in frail and pre-frail adults aged ≥ 65 years to determine the key variables of RT. Ten randomized controlled trials involving 1303 participants were analyzed. Five studies assessed habitual walking speed (HWS), three studies evaluated performance in the timed-up-and-go test (TUG), three studies evaluated performance in the Short Physical Performance Battery (SPPB), and three studies assessed performance in the sit-to-stand test (STS). RT alone improved STS time and SPPB scores in frail and pre-frail older adults. RT improved STS performance (Effect Size (ES):- 0.536; 95% CI - 0.874 to - 0.199; p = .002) and led to a 2.261-point increase in SPPB performance (ES:1.682; 95% CI 0.579-2.786; p = .003). At least two weekly training sessions are required to increase SPPB scores, and three sessions seem to optimize the improvements. Higher training volume per exercise and volume per session reduce the gains in SPPB performance. We did not observe any association between different doses of RT and STS time improvements. RT alone positively influenced TUG performance only in community-dwelling older frail and pre-frail adults but not in institutionalized older individuals. RT alone did not improve the HWS compared to the non-active control group.

Exergaming in the treatment of gait, balance, and quality of life in Parkinson's disease: Overview of systematic reviews.

INTRODUCTION: Postural instability and gait impairments are common in people with PD, both of which have a negative effect on their quality of life. Systematic reviews have demonstrated benefits of using exergaming in enhancing these outcomes. However, there is no consensus over whether exergaming therapy is better than conventional physical therapy for enhancing gait, balance, and quality of life. OBJECTIVES: The aim of this overview is to systematically synthesize and evaluate the available evidence found in published systematic reviews and meta-analyses, on the effects of exergaming therapy on balance, gait, and quality of life, compared to conventional physical therapy or no intervention. METHODS: This overview was reported in accordance with the statement of Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA). A comprehensive search was carried out in nine databases. Two reviewers independently extracted data using a standardized forms and the search strategy included terms related to intervention, population, and study type. The methodological quality of the included systematic reviews/meta-analysis (SRs/Mas) was evaluated using the "A Measurement Tool to Assess Systematic Reviews 2" (AMSTAR-2). The "Grading of Recommendations Assessment, Development and Evaluation" (GRADE) was used to assess the quality of the evidence. The risk of bias assessment was performed using the "Risk Of Bias In Systematic Reviews" (ROBIS). PROSPERO registration number: CRD42021238131. RESULTS: 112 SRs/MAs were found and nine of them were selected. Six reviews were rated as very low methodological quality and three reviews as low methodological quality. Five reviews were classified with low risk of bias and four reviews with high risk of bias. Most of the SR/MAs demonstrated significant effects on balance favoring exergaming therapy over conventional therapy, however those studies had been rated as very low quality of evidence. Inconclusive results were found for the quality of life and gait outcomes. CONCLUSION: Exergaming therapy shows promise for the rehabilitation of PD. However, this overview was unable to conclude with certainty that exergaming therapy is superior to conventional physical therapy in improving gait, balance, or quality of life in people with PD. The effectiveness of exergaming therapy in the treatment of people with PD still need to be verified by high-quality studies.

Atletas de Taekwondo apresentam desequilíbrio muscular entre os músculos flexores e extensores do joelho: achados preliminares / Taekwondo athletes have muscle imbalance between knee flexors and extensions: preliminary findings / Los atletas de Taekwondo presentan un desequilibrio muscular entre los flexores y los extensores de la rodilla: hallazgos preliminares

Durante a prática de taekwondo com movimentos repetitivos, sistematizados e com certa sobrecarga de treino, o indivíduo pode gerar possíveis adaptações orgânicas que resultam em problemas posturais com grandes chances de desencadear desequilíbrio muscular. Objetivo: Verificar a presença de desequilíbrio entre os grupos musculares agonistas e antagonistas da articulação do joelho e entre membros dominantes e não dominantes de praticantes de taekwondo por meio da dinamometria isocinética. Método: Estudo transversal, observacional e descritivo realizado com nove praticantes de taekwondo do sexo masculino. Utilizou-se um dinamômetro isocinético para investigar o pico de torque, pico de torque por peso corporal, trabalho total, potência média, relação agonista/antagonista e índice de fadiga. Os dados dos membros dominante e não dominante foram comparados por meio do teste t-student para amostras pareadas. Foram calculados o intervalo de confiança de 95% da diferença média, o tamanho de efeito e o poder das análises. Resultados: Os músculos extensores dos membros dominante e não dominante apresentaram diferença média significante de 15,49 Nm (IC95% 7,27; 23,70; p=0,002) para pico de torque e de 22,64% (IC95% 11,83; 33,46; p=0,001) para pico de torque por peso corporal a 60°/s, representando tamanho de efeito médio. Conclusão: Os atletas de taekwondo apresentaram maior pico de torque e maior pico de torque por peso corporal dos músculos extensores do joelho a 60º/s no lado dominante. A relação agonista/ antagonista foi inferior a 60% e mais da metade dos atletas apresentaram uma diferença maior que 10% no pico de torque flexor no lado não dominante.

During taekwondo practice with the repetitive motions, systematized and with certain training overload, the person can generate possible organic adaptations that result in postural problems with a great chances of triggering muscle imbalance. Objective: To verify the presence of imbalance between agonist and antagonist muscle groups of knee joint and between dominant and non-dominant limbs through isokinetic dynamometry. Methods: Cross-sectional, observational and descriptive study realized with nine male taekwondo practitioners. An isokinetic dynamometer was used to investigate the peak torque, peak torque by body weight, total work, average power, agonist/antagonist ratio and fatigue index. Data from the dominant and non-dominant limbs were compared by t-student test for pared samples. The 95% confidence interval of the mean difference, the effect size and the power of analyses power were calculated. Results: The extensor muscles of the dominant and non-dominant limbs showed mean difference of 15,49 Nm (IC95% 7,27; 23,70; p=0,002) for peak torque and of 22,64% (IC95% 11,83; 33,46; p=0,001) for peak torque by body weight at 60°/s, representing average effect size. Conclusion: The taekwondo athletes had higher peak torque and higher peak torque by body weight of the knee extensors muscles in the dominant side. The agonist/ antagonist ratio was less than 60% and more than half of the athletes showed a difference greater than 10% in the peak flexor torque on the non-dominant side.

Conclusiones: Los atletas de taekwondo presentaron un mayor par máximo y un mayor par máximo por peso corporal de los músculos extensores de la rodilla en el lado dominante. La relación agonista/antagonista fue inferior al 60% y más de la mitad de los atletas mostraron una diferencia superior al 10% en el pico de par flexor en el lado no dominante.

Association between isokinetic strength measures and functional performance in community-dwelling older adults / Asociación entre las medidas de fuerza isocinética y el rendimiento funcional en personas mayores en la comunidad / Associação entre medidas de força isocinética e desempenho funcional em pessoas idosas da comunidade

ABSTRACT Previous studies have shown an association between lower limb muscle strength and functional performance, but a dose-response relationship between the strength of each lower limb muscle group and performance in daily life activities in older adults has not been well established. Thus, this study aimed to investigate the association between isokinetic muscle strength of all eight major lower limb muscle groups and functional performance in community-dwelling older adults. The muscle strength of the plantar flexors and dorsiflexors of the ankle, flexors and extensors of the knee, and flexors, extensors, adductors, and abductors of the hip were evaluated using a Biodex System 4 Pro® isokinetic dynamometer. Functional performance was evaluated in 109 participants using the five-times sit-to-stand test (STS) and 4-meter usual walking speed (UWS). The multiple linear regression analyses showed that the hip abductors strength predicted 31.3% of the variability for UWS (p=0.011), and the knee extensors strength (p=0.015) predicted 31.6% of the variability for the STS. We conclude that hip abductors and knee extensors could be the key muscle groups involved in sit to stand and walking speed performance in older adults.

RESUMEN Estudios previos ya demostraron la asociación entre la fuerza muscular de los miembros inferiores y el rendimiento funcional, sin embargo, no está bien establecida la contribución de los principales músculos de los miembros inferiores sobre el rendimiento de las personas mayores en las actividades diarias. El objetivo de este estudio fue evaluar la asociación entre la fuerza muscular isocinética de los ocho principales grupos musculares de los miembros inferiores y el rendimiento funcional en personas mayores que viven en la comunidad. La fuerza muscular de los plantiflexores y dorsiflexores del tobillo, los flexores y extensores de la rodilla y los flexores, extensores, aductores y abductores de la cadera se evaluaron por medio del dinamómetro isocinético Biodex System 4 Pro®. El rendimiento funcional de 109 participantes se evaluó mediante el test de sentarse y pararse cinco veces (STS) y la velocidad de marcha habitual de 4 metros. Los análisis de regresión lineal múltiple mostraron que la fuerza de los abductores de la cadera predijo el 31,3% de la variabilidad para la velocidad de marcha habitual (p=0,011); y la fuerza de los extensores de la rodilla (p=0,015), el 31,6% de variabilidad para STS. Se concluyó que los abductores de la cadera y los extensores de la rodilla pueden ser los principales grupos musculares involucrados en el rendimiento de los adultos mayores para sentarse, pararse y caminar.

RESUMO Estudos anteriores já demonstraram a associação entre força muscular de membros inferiores e desempenho funcional, mas a contribuição dos principais músculos dos membros inferiores para o desempenho de pessoas idosas nas atividades cotidianas não foi bem estabelecida. O objetivo deste estudo foi investigar a associação entre a força muscular isocinética dos oito principais grupos musculares dos membros inferiores e o desempenho funcional em pessoas idosas da comunidade. A força muscular dos plantiflexores e dorsiflexores do tornozelo, flexores e extensores do joelho e flexores, extensores, adutores e abdutores do quadril foi avaliada utilizando um dinamômetro isocinético Biodex System 4 Pro®. O desempenho funcional de 109 participantes foi avaliado usando o teste de sentar e levantar cinco vezes (TSL) e de velocidade de marcha habitual de 4 metros (VMH). As análises de regressão linear múltipla mostraram que a força dos abdutores do quadril previu 31,3% da variabilidade para a VMH (p=0,011), e a força dos extensores do joelho (p=0,015) 31,6% da variabilidade para o TSL. Concluímos que os abdutores do quadril e os extensores do joelho podem ser os principais grupos musculares envolvidos no desempenho de pessoas idosas para sentar-levantar e caminhar.

Contributions of social participation to the dynamic balance, mobility, and muscle strength of different age groups of older people: a cross-sectional study / Contribuições da participação social para equilíbrio dinâmico, mobilidade e força muscular de diferentes faixas etárias de idosos: um estudo transversal / Contribuciones de la participación social al equilibrio dinámico, la movilidad y la fuerza muscular de diferentes grupos de edad de ancianos: un estudio transversal

ABSTRACT This study aimed to investigate the contributions of social participation in health promotion groups and regular physical exercise programs to the physical and functional performance of different age groups of community-dwelling older adults. This is a cross-sectional study including 266 older adults. Physical and functional performances (dependent variables) were characterized based on dynamic balance (alternate step test), mobility (timed up and go test), upper (handgrip dynamometer) and lower limbs muscle strength (Sit-to-stand test). Participants were questioned about active social participation in primary care groups and in physical exercise programs. The data were analyzed by linear regressions. Among individuals aged over 80 years, women participated in less health promotion groups and both sexes practiced less physical exercise. Age combined with regular exercise significantly explained 18.7% of dynamic balance and 22.8% of lower limb muscle strength in women. Despite social participation, for men, age alone explained 11.9% of lower limb strength and 11.5% of mobility. Therefore, social participation in physical exercise programs was a protective factor for these physical and functional differences between women's age groups. Among men, mobility and lower limb strength performance reduced with aging, regardless of social participation.

RESUMO O objetivo deste estudo foi investigar as contribuições da participação social em grupos de promoção de saúde e programas de exercícios físicos regulares para o desempenho físico e funcional de idosos comunitários de diferentes faixas etárias. Para tanto, realizou-se um estudo transversal com 266 idosos. O desempenho físico e funcional (variáveis dependentes) foi caracterizado com base no equilíbrio dinâmico (teste de degrau alternado), na mobilidade (teste timed up and go), na força muscular dos membros superiores (dinamômetro de preensão manual) e inferiores (teste de sentar e levantar). Os participantes foram questionados sobre sua participação social ativa em grupos de atenção primária e em programas de exercícios físicos. Os dados foram analisados por regressões lineares. Entre os indivíduos com 80 anos ou mais, as mulheres participaram menos de grupos de promoção de saúde, e ambos os sexos praticaram menos exercícios físicos. A idade combinada com o exercício regular explicou significativamente 18,7% do equilíbrio dinâmico e 22,8% da força muscular dos membros inferiores em mulheres. Para os participantes do sexo masculino, independentemente da participação social, apenas a idade explicou 11,9% da força dos membros inferiores e 11,5% da mobilidade. Verificou-se que a participação social em programas de exercícios físicos foi um fator protetor, entre as mulheres, para essas diferenças físicas e funcionais entre faixas etárias. Entre os homens, o desempenho de mobilidade e força dos membros inferiores foi piorando conforme o aumento da idade, independentemente da participação social.

RESUMEN El objetivo de este estudio fue investigar las contribuciones de la participación social en grupos de promoción de la salud y en programas de ejercicio físico regular para el desempeño físico y funcional de ancianos residentes en comunidad de diferentes grupos de edad. Para ello, se realizó un estudio transversal con 266 ancianos. El rendimiento físico y funcional (variables dependientes) se caracterizó con base en el equilibrio dinámico (prueba de escalón alterno), en la movilidad (prueba timed up and go), en la fuerza muscular de los miembros superiores (dinamómetro de agarre manual) y miembros inferiores (prueba de levantarse y sentarse). Las preguntas del cuestionario versaban sobre la participación social activa de los encuestados en grupos de atención primaria y en programas de ejercicio físico. Los datos se analizaron mediante regresiones lineales. Entre las personas de 80 años o más, las mujeres participaban menos en los grupos de promoción de la salud y ambos sexos practicaban menos ejercicio físico. La combinación edad y ejercicio regular explicó significativamente el 18,7% del equilibrio dinámico y el 22,8% de la fuerza muscular de los miembros inferiores en las mujeres. Para los participantes del sexo masculino, independientemente de la participación social, la edad por sí sola explicó el 11,9% de la fuerza de los miembros inferiores y el 11,5% de la movilidad. Se encontró que la participación social en programas de ejercicio físico fue un factor protector entre las mujeres para estas diferencias físicas y funcionales entre los grupos de edad. Entre los hombres, el rendimiento de la movilidad y fuerza de las extremidades inferiores empeoró conforme el aumento de la edad, independientemente de la participación social.

Methods: This is a cross-sectional, observational and descriptive study that included regular male BJJ practitioners aged between 18 and 40 years. A basic questionnaire was created to collect variables: age, graduation, time practicing martial art, frequency of training, practice of other physical activities and frequency. For the investigation of pain complaints, the Nordic Questionnaire of Musculoskeletal Symptoms - NQSO, adapted Portuguese version, was applied. Data were recorded in the Microsoft Excel 365 program and descriptive statistics were performed. Results: The 52 research participants had average an age of 32 years old and average time of 9 years of BJJ practice, 50% of them were blue belt graduation. The practitioners presented 45 reports of complaints in the week before the application of NQSO, 76 reports in previous year, 43 reports that led to withdrawal training and 20 reports of previous injuries in the previous year. Conclusion: The highest prevalence of complaints in the previous 7 days of the application of NQSO occurred in the knees, lumbar spine and hip- thighs, and in the previous 12 months occurred in the knees, lumbar spine and shoulders. The major prevalence that led to withdrawal training in the previous 12 month occurred in the knees, lumbar spine and ankle-foots, and the complaints of previous injuries occurred in the knees, wrists and shoulders.

Associação dos parâmetros clínicos de sarcopenia e comprometimento cognitivo em pessoas idosas: estudo transversal / Association of clinical parameters of sarcopenia and cognitive impairment in older people: cross-sectional study

Resumo Objetivo Associar os parâmetros clínicos de sarcopenia com o comprometimento cognitivo em pessoas idosas. Método Estudo transversal, com 263 idosos (≥60 anos) usuários de um serviço público de atenção especializada. Variáveis sociodemográficas e clínicas caracterizaram a amostra e os parâmetros clínicos de sarcopenia (força, massa muscular e desempenho físico) foram avaliados, respectivamente, por meio da Força de Preensão Palmar (FPP), circunferência da panturrilha (CP) e o Teste Timed Up and Go (TUG). Utilizou-se o Miniexame do Estado Mental (MEEM) para avaliar o estado cognitivo. As associações foram investigadas por regressões lineares e logísticas simples e múltiplas considerando os parâmetros clínicos de sarcopenia (variáveis independentes) e o estado cognitivo (variável dependente), ajustadas para idade, sexo, anos de estudo, número de medicação, estado nutricional e capacidade funcional. Resultados Dos participantes com comprometimento cognitivo, 59,6% apresentaram baixa força muscular. O Conclusão A baixa força muscular foi o parâmetro de sarcopenia independentemente associado ao comprometimento cognitivo. Essa informação é útil para atentar-se para a probabilidade de comprometimento cognitivo quando identificada baixa força muscular em pessoas idosas.

Abstract Objective To associate clinical parameters of sarcopenia with cognitive impairment in older people. Method Cross-sectional study with 263 older adults (≥60 years) treated at a specialized public health facility. Sociodemographic and clinical variables were used to characterize the sample and the clinical parameters of sarcopenia (muscle strength, muscle mass and physical performance) were assessed based on handgrip strength (HGS), calf circumference (CC) and the Timed Up and Go (TUG) test. The Mini-Mental State Examination (MMSE) was used to evaluate cognitive status. Associations were analyzed by simple and multiple linear and logistic regression considering the clinical parameters of sarcopenia (independent variables) and cognitive status (dependent variable), adjusted for age, sex, years of schooling, number of medications, nutritional status and functional capacity. Results Of participants with cognitive impairment, 59.6% exhibited low muscle strength. Conclusion Low muscle strength was the sarcopenia parameter independently associated with cognitive impairment. This information is useful in highlighting the likelihood of cognitive impairment when poor muscle strength is identified in older people.

Effectiveness of Pilates and circuit-based exercise in reducing arthralgia in women during hormone therapy for breast cancer: a randomized, controlled trial.

OBJECTIVE: To investigate the effect of Pilates compared with circuit-based exercise in reducing arthralgia in women during hormone therapy for breast cancer. DESIGN: Single-blind randomized controlled trial, parallel. SETTING: University hospital of Brasilia and Brazilian Association for Assistance to People with Cancer. PARTICIPANTS: Sixty women with arthralgia were recruited. Eligibility criteria included women complaining of arthralgia during hormone therapy for breast cancer. The exclusion criteria were women with active cancer, lymphedema, limitations to physical exercise, or limitation to answer some questionnaires. MAIN OUTCOME MEASURES: Primary: Pain. Secondary: Function, flexibility, and sleep quality. Outcomes were assessed at baseline and the end of the intervention (8 weeks) by the same blinded evaluator. INTERVENTION: Sixty participants were randomly assigned 20 to each of the three groups: Pilates, circuit-based exercise, and control groups. Exercise was performed twice per week for 75 min, over a period of 8 weeks. Participants in the control group were instructed to continue their usual activities. The Kolmogorov-Smirnov test was used to verify the normality of the outcomes. Intergroup differences were calculated using Kruskal-Wallis test with post hoc Mann Whitney U testing and the parametric data between the three groups with ANOVA of repeated measures with Bonferroni post hoc. RESULTS: The Pilates group demonstrated a significant difference in pain reduction compared to the circuit group (mean difference: -1.95 points, p = 0.020). CONCLUSION: Pilates was more effective than circuit-based exercise in reducing arthralgia in women during hormone therapy for breast cancer.

Obesity is associated with postural balance on unstable surfaces but not with fear of falling in older adults.

BACKGROUND: There are inconsistent findings regarding the relationship between body mass index (BMI), fear of falling and body balance, especially on unstable surfaces. OBJECTIVES: To investigate whether obesity is associated with worse postural balance and fear of falling in older adults. METHODS: A cross-sectional study was conducted with 201 older adults, classified as normal weight, overweight, or obese according to BMI. Postural balance was evaluated on stable and unstable surfaces on the Biodex Balance System platform under three visual conditions: with and without visual feedback and with eyes closed. Fear of falling was identified by a dichotomous question and the Falls Efficacy Scale. These data were compared between groups and included in adjusted multiple linear regression analysis. RESULTS: The study showed no significant differences (p > 0.05) in body oscillations on a stable surface between the three groups. On an unstable surface, the obese older adults exhibited body oscillations from 0.61° [95% CI 0.07, 1.30] to 1.63° [95% CI 0.84, 2.41] greater than those with normal weight in the three visual conditions. The obese older adults also displayed larger mediolateral oscillations with visual feedback (mean difference: 0.50° [95% CI 0.01, 0.98]) as well as greater global oscillations without visual feedback (mean difference of 0.82° [95% CI 0.18, 1.81]) and with progressive instability (mean difference: 0.80° [95% CI 0.05, 1.66]) than the overweight older adults. BMI explained from 6 to 12% of body swings investigated on unstable surface. Obesity was not associated with fear of falling. CONCLUSION: Obesity was associated with reduced postural stability on unstable surfaces but not with fear of falling in older adults.

Transcutaneous tibial nerve stimulation versus parasacral stimulation in the treatment of overactive bladder in elderly people: a triple-blinded randomized controlled trial.

OBJECTIVES: To evaluate the effect of transcutaneous tibial nerve stimulation (TTNS) and transcutaneous parasacral stimulation on the treatment of overactive bladder (OAB) in elderly people and to compare the final results between groups. METHODS: Fifty female volunteers, mean age 68.62 (±5.9) years, were randomly allocated into two groups: those receiving TTNS (G1, N=25) and those receiving transcutaneous parasacral stimulation (G2, N=25). The primary outcome was the International Consultation on Incontinence Questionnaire (ICIQ-OAB) score, and secondary outcomes were the International Consultation on Incontinence Questionnaire - short form (ICIQ-SF) score and 3-day bladder diary measurements. Volunteers were assessed before and after the treatment. Clinical Trials (ReBeC): RBR-9Q7J7Y. RESULTS: Both groups' symptoms improved as measured by the ICIQ-OAB (G1 = <0.001; G2 = <0.001) and ICIQ-SF (G1 = <0.001; G2 = <0.001). In the 3-day bladder diary assessments after treatment, G1 showed a reduced number of nocturia (p<0.001), urgency (p<0.001) and urge urinary incontinence episodes (p<0.001), whereas G2 showed only a reduced number of nocturia episodes (p<0.001). No difference between groups was found. CONCLUSION: Both of the proposed treatments were effective in the improvement of OAB symptoms, but TTNS showed a reduction in a greater number of symptoms as measured by the 3-day bladder diary. No differences were found between groups.

The influence of isokinetic peak torque and muscular power on the functional performance of active and inactive community-dwelling elderly: a cross-sectional study.

OBJECTIVE: To verify the importance of the isokinetic muscular torque and power of knee extensors and flexors on the functional performance of active and inactive elderly women. METHODS: A cross-sectional observational study was conducted with 116 community-dwelling women (≥60 years old) without severe cognitive and/or motor dysfunction. Isokinetic muscle function was measured by peak torque and muscle power at 60°/s (5 repetitions) and 180°/s (15 repetitions), respectively. Mobility was evaluated by means of the Timed Up and Go test (TUG) and the Habitual Gait Speed (HGS) test. Balance was evaluated via the alternate step and semitandem tests. Lower limb strength was assessed using the Sit-to-stand test. Univariate and multivariate logistic regression analysis was used to determine association between independent and dependent variables (α=0.05). RESULT: Active elderly women had better muscle function and functional performance than inactive elderly women for almost all variables. Peak torque and muscular power of knee extensor muscles explained the dynamic balance, mobility, and lower limb strength among inactive elderly women (OR: 0.89-0.95; p<0.05). Muscular power of knee flexors influenced tasks that required mobility and lower limb strength among active elderly (OR: 0.82-0.87; p<0.05). CONCLUSIONS: The muscular power of knee flexors was shown to be more important for the functional performance of active elderly women. The muscular power of knee extensors had a stronger influence on the performance of the inactive elderly women.

Dynamic and Static Postural Control in Volleyball Players with Transfemoral Amputation / Controle Postural Dinâmico e Estático em Jogadores de Vôlei com Amputação Transfemoral / Control Postural Dinámico y Estático de Jugadores de VÓLEY con Amputación Transfemoral

ABSTRACT Introduction: A decrease in postural control and proprioception is a common result of lower limb amputation. However, postural control adaptation in Paralympic sitting volleyball players with lower limb amputation is not yet understood. Objective: The purpose of this cross-sectional controlled study was to investigate static and dynamic postural control in sitting volleyball players with unilateral transfemoral amputation. Methods: Sixteen subjects participated in the study, eight of whom were amputees with unilateral transfemoral amputation (amputee group: age: 33.5 ± 5.6 years, weight: 77.7 ± 5.3 kg, height: 179.4 ± 5.3 cm) and eight physically active non-amputees (control group age: 27.2 ± 8.4 years, weight: 82.7 ± 6.6 kg, height: 178.7 ± 6.1 cm). Static and dynamic postural control was evaluated using the Neurocom® Balance Master System platform (Modified Clinical Test of Sensory Interaction on Balance, Limits of Stability, Rhythmic Weight Shift, Sit-to-Stand, Walk Across, and Step and Quick Turn). Statistical analyses were performed with the Shapiro-Wilk test, Levene's test, and Student's t-test for paired samples (p <0.05). Results: The amputee group demonstrated impaired postural control in all tests when compared to the control group (p <.05) for all postural tests except for the rhythmic change and sit-to-stand tests (p >.05). Conclusion: Despite training in sitting volleyball, our results demonstrated that amputees have poorer postural control in both static and dynamic tasks when compared to physically active non-amputees.

Accuracy of clinical-functional tools to identify risk of falls among community-dwelling older adults / Acurácia de ferramentas clínico-funcionais para identificar risco de quedas em idosos comunitários / Precisión de herramientas clinico-funcionales para identificar riesgo de caídas em ancianos comunitários

Abstract Introduction: The identification of older adults who present greater chances of falling is the first step in the prevention of falls. Clinical instruments have been shown to be able to differentiate fallers from non-fallers, but their predictive validity remains controversial. Objective: To investigate the accuracy of the Short Physical Performance Battery (SPPB) and Quick Screen Clinical Fall Risk Assessment (QuickScreen) instruments to identify risk of falls in community-dwelling older adults. Method: This is a prospective methodological study with 81 older adults (≥ 60 years), assessed at baseline by SPPB and QuickScreen and monitored after one year to identify the occurrence of falls. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and area under the ROC curve (AUC) were calculated. Results: 28.4% of the sample reported falls. QuickScreen presented 52.2% sensitivity, 74.1% specificity, 44.4% PPV, 79.6% NPV and 0.656 AUC. The AUC for SPPB was not significant (p = 0.087). Conclusion: QuickScreen presented poor accuracy when predicting falls and SPPB was unable to identify community-dwelling older adults at risk of falls. The QuickScreen instrument stood out for its high potential to identify true negatives.
