Time up and Go Classic, Manual and Cognitive: prediction analysis of the risk of falling physically active elderly

Resumo

Abstract

Elderly falls affect public health, which justifies the evaluation of their risk. The present study analyzed gait performance of physically active elderly women by means of the test, predicting the risk of falls in this population, as well as determining the levels of sensitivity and specificity of these tests. A quantitative cross-sectional study was carried out with 191 women (67,30±5,13 years), practicing Pilates and water aerobics, divided into fallers and non-fallers groups. The tests applied were the classic Time Up and Go (TUG), its manual version (TUGm) and cognitive (TUGc). A drop rate of 28.8% was found. Participants from both groups did not indicate performance deficits in the evaluation of TUG, TUGm and TUGc (p≥0.05). According to the logistic regression analysis, the TUG, TUGm and TUGc tests did not explain the occurrence of falls (p≥0,05). The ROC curve showed an accuracy of 0.520 for TUG (p=0.673), 0.517 for TUGm (0.711) and 0.526 for TUGc (p=0.570). The cut-off points suggested to determine the risk of falling for TUG, TUGm and TUGc were ≤9,95sec., ≥10,35sec. and ≥11,30 sec., respectively. The TUG, TUGm, and TUGc tests showed predictive capacity and low diagnostic accuracy, thus reduced competence to discriminate fallers from non-fallers  among physically active elders. Its application is suggested in association with balance tests, lower limb strength and gerontological scales.

Resumo

Quedas de idosos incidem em questão de saúde pública, o que justifica a avaliação do seu risco. O presente estudo analisou o desempenho da marcha de idosas fisicamente ativas por meio do teste, predizendo o risco de queda dessa população, além de determinar os níveis de sensibilidade e especificidade desses testes. Estudo transversal quantitativo desenvolvido com 191 mulheres (67,30±5,13 anos) praticantes do Pilates e hidroginástica, divididas em grupo caidor e não-caidor. Os testes aplicados foram o Time Up and Go (TUG) clássico, sua versão manual (TUGm) e cognitiva (TUGc). Verificou-se taxa de queda de 28,8%. Participantes de ambos os grupos não indicaram déficits de desempenho na avaliação do TUG, TUGm e TUGc (p≥0,05). Segundo a análise de regressão logística, os testes TUG, TUGm e TUGc não explicaram a ocorrência de quedas (p≥0,05). A curva ROC apontou acurácia de 0,520 para o TUG (p=0,673), 0,517 para o TUGm (0,711) e 0,526 para o TUGc (p=0,570). Os pontos de corte sugeridos à determinação do risco de queda para o TUG, TUGm e TUGc foram ≤9,95seg., ≥10,35seg. e ≥11,30 seg., respectivamente. Os testes TUG, TUGm e TUGc mostraram capacidade preditiva e acurácia diagnóstica baixa, logo reduzida competência para discriminar caidores de não-caidores entre idosas fisicamente ativas. Sugere-se sua aplicação associada à testes de equilíbrio, força de membros inferiores e escalas gerontológicas.
