Gait variability is related to functional decline in the elderly. The dual-task Timed Up and Go Test (TUG-DT) reflects the performance in daily activities. Objective: To evaluate the differences in time to perform the TUG with and without DT in elderly women with different ages and levels of education and physical activity. Method: Ninety-two elderly women perfomed the TUG at usual and fast speeds, with and without motor and cognitive DT. Results: Increases in the time to perform the TUG-DT were observed at older ages and lower educational levels, but not at different levels of physical activity. More educated women performed the test faster with and without DT at both speeds. When age was considered, significant differences were found only for the TUG-DT at both speeds. Conclusion: Younger women with higher education levels demonstrated better performances on the TUG-DT.Keywords: elderly, gait, Timed Up and Go, dual task. RESUMOAlterações da marcha são indícios de declínio funcional em idosos. O TUG com dupla tarefa (TUG-DT) reflete o desempenho das atividades do cotidiano. Objetivo: Avaliar as diferenças no tempo de execução do TUG com e sem DT em idosas com diferentes faixas etárias, e níveis de escolaridade e atividade física. Método: Noventa e duas idosas foram avaliadas pelo TUG nas velocidades usual e máxima, sem e com DT cognitiva e motora. Resultados: Houve aumento no tempo de execução do TUG-DT em idosas com maior faixa etária e menor escolaridade, mas não para diferentes níveis de atividade física. Aquelas com maior escolaridade realizaram o teste mais rápido com e sem DT nas duas velocidades. Com relação à faixa etária, foram obervadas diferenças apenas nos testes com DT nas duas velocidades. Conclusão: Idosas mais jovens com maior escolaridade demonstraram um melhor desempenho no TUG com DT.Palavras-chave: idosos, marcha, teste Timed Up and Go, dupla tarefa.The aging rate has been growing rapidly worldwide in the last decades, and this has exerted strong influences on the dynamics of the society development 1 , with increases in chronic and degenerative diseases, higher dependency indices, and high rates of institutionalization and hospitalization 1 . Functional capacity (FC) refers to the competence of the individuals to preserve their physical and mental abilities necessary for an independent life. FC is an important marker of healthy, independent, and successful aging and has a positive impact on quality of life, especially regarding motor abilities 2 . Changes in gait patterns and speeds are related to difficulties in performing everyday activities, and indicate functional declines and hospitalization in individuals above 75 years of age 3,4 . Several studies have shown increased activation and inter-relations of brain structures related to cognition and
Introduction: The physiological deterioration associated with ageing exposes elderly persons to greater risks of falls, especially during the performance of simultaneous tasks during gait. Objectives: To evaluate the effects of dual tasks (DT) on spatiotemporal gait parameters and to identify the tools and tasks most commonly used to assess the performance of DT among the elderly. Method: Searches of the MEDLINE, PsycINFO, CINAHL, and SciELO databases were conducted. Observational studies, which evaluated gait changes during the performance of DT, published up to April 2014, were selected. Results: A total of 385 articles were found, of which 28 were selected. Decreases in speed and increases in stride variability, stride time, step width, and double support time were observed under DT conditions. Motion analysis systems, such as the GAITRite walkway® system were the mostly commonly used instruments for the analyses of kinematic parameters (16 studies). DT was most commonly assessed by arithmetic calculations in 20 studies, followed by verbal fluency, in nine studies. The gait parameters most commonly assessed were speed (19 studies), followed by stride variability (14 studies). Conclusion: The elderly showed changes in spatiotemporal gait parameters under DT conditions. Gait speed and stride variability were often assessed and, together, were considered good indicators of risks of falls.
| Vulnerability is the individual's capacity to suffer damage in response to a stimulus. We identified physical vulnerability in older people in hospital discharge; the association of this condition with sociodemographic factors was verified, and we compared vulnerable with not-vulnerable individuals, as well as those referred or not to physical therapy during hospitalization. This was an exploratory study, and the sample consisted of 122 hospitalized older adults. Data were collected using a socio-clinical demographic questionnaire, the RESUMEN | Vulnerabilidad es la capacidad de un individuo sufrir daño en respuesta a un estímulo. Se identificó la vulnerabilidad física de ancianos en el alta hospitalaria y la asociación de esa condición con factores clínicos y sociodemográficos, y fueron comparados ancianos vulnerables con los no vulnerables y aquellos acompañados o no por la fisioterapia durante el ingreso. Este fue un estudio exploratorio, con muestra de 122 ancianos hospitalizados. Los datos fueron obtenidos por medio de cuestionario clínico y sociodemográfico, Mini Prueba del Estado Mental, Escala de Depresión Geriátrica y Vulnerable Elders Survey-13. Se utilizó para tanto la prueba de correlación de Spearman para identificar la correlación entre la vulnerabilidad y los datos clínicos y los sociodemográficos y la prueba de Mann-Whitney. El nivel de significancia fue de un 5%. La vulnerabilidad fue identificada en el 75,4% de los ancianos. Hubo correlación significativa entre la vulnerabilidad y la edad (r=0,52 p=0,01), el tiempo de ingreso (r=0,25 p=0,01) y el número de comorbidades (r=0,25 p=0,01), y la negativa entre la vulnerabilidad y la escolaridad (r=-0,20 p=0,02).Hubo diferencia estadística entre ancianos vulnerables y los no vulnerables para la edad (p=0,01), las comorbidades (p=0,01), el tiempo de ingreso (p=0,01), el MEEM (p=0,01) y el GDS (p=0,01), y entre los ancianos acompañados o no por la fisioterapia para la vulnerabilidad (p=0,04) y el tiempo de ingreso (p=0,01). La gran parte de los ancianos era físicamente vulnerable en el alta hospitalaria, siendo ellos más mayores, con más comorbidades, el tiempo de ingreso más grande, la presencia de descenso cognitivo y los síntomas depresivos. Aquellos que recibieron acompañamiento fisioterapéutico presentaron la vulnerabilidad y el tiempo de ingreso más grandes.Palabras clave | Anciano; Hospitalización; Estudio de Vulnerabilidad; Vulnerabilidad en Salud.
Resumo O estudo investigou a prevalência de declínio da capacidade funcional e seus fatores associados em idosos adscritos à Estratégia Saúde da Família (ESF), em um município do sul de Minas Gerais. Estudo observacional, transversal, de base populacional, com 406 idosos. A capacidade funcional foi avaliada pelo Short Physical Performance Battery (SPPB); seus fatores associados foram avaliados por um questionário estruturado incluindo aspectos sociodemográficos, econômicos, clínicos e físicos. Concentrações de mediadores inflamatórios foram dosadas pelo método de Elisa (“Enzyme-Linked Immunosorbent Assay”). Regressão linear múltipla foi usada para as análises (p < 0,05). A prevalência de declínio funcional na amostra foi de 57,6% e os fatores associados à capacidade funcional foram: idade avançada, sexo feminino, número de medicamentos, sintomas depressivos, elevadas concentrações plasmáticas de receptor solúvel 1 do fator de necrose tumoral alfa (sTNFR1) e baixa força de preensão palmar. Os resultados mostraram que a capacidade funcional foi associada a uma rede de fatores multidimensionais. O presente estudo contribui para a prática de profissionais na ESF ao apontar os principais fatores que podem nortear as ações de promoção e prevenção do declínio da capacidade funcional na população idosa.
