Effect on Physical Functions of Older Adults When Refraining from Going out due to COVID-19 Restrictions

Abstract

Abstract: The study investigated the effect of refraining from going out during the coronavirus disease 2019 pandemic on physical function in community-dwelling older adults. The study included 49 patients who underwent home-visit rehabilitation. Four parameters of physical function—grip strength, five-times sit-to-stand test, single-leg stance test, and standing test for imbalance and disequilibrium (SIDE)—were assessed. They were evaluated before (March 2020) and after (May 2020) the state emergency was imposed, and the results were compared. The grip strength decreased significantly. A significant difference was also observed in the proportion of different SIDE levels in the study group before and after the implementation of the state emergency. The number of SIDE 2a or lower patients increased during the state emergency (p < 0.001). Comprehensive community support and rehabilitation are necessary to maintain physical function in older individuals. In particular, we believe that there is a need to utilize remote rehabilitation using digital devices (such as internet-based guidance) so that older adults can continue to exercise at home.
