Indicadores de desempenho motor como preditores de fragilidade em idosos cadastrados em uma Unidade de Saúde da Família/Motor performance indicators as fragility predicts in elderly registered in a Family Health Unit

This study aimed to identify the motor performance tests more strongly associated with frailty and respective cut-off points, and verify the best motor performance indicator as screening tool to discriminate frailty in elderly registered in Family Health Unit. Participated in the study 139 elderly aged >60 years, 105 women and 34 men. The frailty was identified by the criteria of Fried et al. (2001). The motor performance tests realized were: Handgrip strength (HS), sit-to-stand test, walk test (WT) and pick up a pen test. Logistic regression analysis was used to associate the motor performance tests and frailty. The cutoff points were evaluated by parameters provided by Receiver Operating Characteristic curve (ROC), with significance level of 5%. Data were analyzed using SPSS 21.0 and MedCalc. The mean age was 72.32 ± 8.4. The walk test was positively associated with frailty (OR 1.30; p
