Abstract
With the aging of the population becoming more and more serious, the falls of the elderly have gradually become the focus of academia. We build a multidimensional model to evaluate the walking balance ability of the elderly so as to help them correct their postures and prevent possible falls. From the perspective of the state of gravity center, gait and body features, some indicators such as envelope area of gravity center shifting and stride length are extracted to assess the stability of old people’s walking. Then entropy weight method is introduced to build the evaluation model. Finally, the validity of the model is proved by empirical analysis.
