Study on Gait Stability of Gait With Limitation of Dorsiflexion Based on Wavelet Transform

Walking is a common exercise in people's daily life. Gait stability is an important feature of gait. The weakening of gait stability will increase the risk of falling. When people's foot dorsiflexion is limited, it will significantly change the gait stability. The study of gait stability has important research significance for the diagnosis and rehabilitation evaluation of foot dorsiflexion limitation. In this paper, the non-contact electrostatic gait measurement method is used to obtain the human electrostatic gait information, the wavelet transform algorithm is used to process the electrostatic gait signal, in order to analysis energy ratio of the information of the center of gravity conversion frequency band in the entire signal, in addition,the gait stability index is designed. The results show that the gait stability decreases as the degree of dorsiflexion limitation deepens.
