Efeito da realização da Tarefa Dual e suas interferências nos componentes espaços temporais da marcha em idosos da comunidade

Abstract

The elderly are at particular risk of falls as they move through your home while talking with a friend, etc. Most falls in the elderly occur when they are riding and performing a secondary task. This study aims to review literature about the implementation of dual task and its interference in the components and their timelines gait in the community dwellings. Methods: We performed a literature review in the databases of BIREME, Pubmed, Cochrane between May and July 2010 limiting the search to the last five years. With a sample of elderly aged sixty or older, without comorbidities that could interfere in the walking pattern. Results: We selected 13 articles, eight cross-sectional studies, three longitudinal and two randomized studies for the preparation of this review. The combinations of walking and simultaneous visual observation, which are common in everyday life, may contribute to gait disorders and falls in daily activities in old age. Conclusion: In a general analysis, the results indicate that under dual task there is a decrease in stability, higher gait variability and decline in ability to allocate attention resulting in a slowdown of placing the elderly at risk of falls.
