RESUMEN
O envelhecimento promove mudanças na autonomia e dependência dos idosos que associado a fatores adversos pode levar o indivíduo a um estado de fragilidade. Entretanto, a prática de exercícios físicos tem mostrado efeitos positivos na funcionalidade que pode contribuir na diminuição do risco de vulnerabilidade do idoso frágil. Objetivo: Avaliar o efeito dos exercícios nos domínios avaliados pelo Índice de Vulnerabilidade Clinico-funcional (IVCF-20) em idosos frágeis. Método: Cinquenta e seis idosos frágeis de ambos os sexos, atendidos no Centro de Referência em Assistência à Saúde do Idoso - Eny Faria De Oliveira CRASI, foram avaliados por meio do IVCF-20 antes e depois de 10 sessões de fisioterapia. Os 8 domínios que compõem o IVCF-20 foram analisados individualmente. O Teste de Friedman foi utilizado para comparação pré e pós-reabilitação intragrupo. Resultados: Foram observadas diferenças significativas nos domínios de atividades de vida diária, cognição, humor, mobilidade e comunicação pós-treinamento (p<0,01) no grupo feminino e masculino. Conclusão: Programas de exercícios podem contribuir na melhora da mobilidade, cognição e funcionalidade dos idosos frágeis.
Aging promote changes in the autonomy and dependence of the elderly, which associated with adverse factors can lead the individual to a state of fragility. However, the practice of physical exercises has shown positive effects on functionality that can contribute in a reduction in the risk of vulnerability of the frail older adults. Objective: The aim of the study was to evaluate the effect of exercise in the domains assessed by the Clinical-Functional Vulnerability Index (IVCF-20) in frail older adults. Method: Fifty-six frail older adult's people of both sexes, attended at the Health Care Reference Center for the Older Adults - Eny Faria De Oliveira - CRASI, were assessed using the IVCF-20 before and after 10 physiotherapy sessions. The 8 domains that make up the IVCF-20 were analyzed individually. Friedman's ANOVA test was used for pre- and post-rehabilitation comparisons intragroup. Results: Significant differences were observed in the domains of activities of daily living, cognition, mood, mobility, and post-training communication (p<0.01) in the female and male group. Conclusion: exercise programs can contribute to improving the mobility, cognition, and functionality of frail older adults.
RESUMEN
BACKGROUND: Single- and dual-tasks are influenced by age-related impaired postural balance. Aim of this study was to analyze the Center of Pressure (CoP) oscillation during static balance in the presence or absence of cognitive task on older women. METHODS: Thirty-one healthy older women were assessed in a stand quiet position with open/closed eyes (single-task, OE and CE) and with cognitive task (dual-task, DT) through Wii Balance Board. Sway area, total displacement and CoP oscillation (CO) based on the number of times that CoP traveled through anteroposterior and mediolateral directions. Friedman test was used to compare OE, CE and DT. Dual-task interference percentage was used to quantify the cognitive load on balance whereas Spearman correlation coefficient was used to assess the association of cognitive domains and CO. RESULTS: The CO was significantly higher in DT than in single-tasks and participants were unable to maintain their limits of stability in mediolateral direction. The cost of DT interference was 30.5%, which is partially explained by the deviation of attention from postural control to spatial and temporal orientation. CONCLUSION: Our findings show that cognitive load during DT impairs balance in mediolateral direction, thus indicating the use of WBB to assess cognitive interference on postural control.
