Analysis of plantar impact characteristics of walking in patients with flatfoot according to basic mechanical features and continuous wavelet transform

Flatfoot is a common foot deformity, and the collapse of arch structure affects cushioning during walking. A growing number scholars have found that analysis impact force should be combined with both magnitude frequency force. Therefore, aim this study to investigate plantar characteristics flatfoot patients normal people at different load-bearing buffer stage from time domains. Sixteen males sixteen were recruited walk on pressure test system same step speed, vertical ground reaction data collected heel contact support stage. The differences in domain between two stages analyzed according basic mechanical continuous wavelet transform. Independent sample t -test was used compare baseline subjects, type weight-bearing cushion phase compared by two-factor repeated measures Analysis Variance. 1) In terms characteristics, groups for people, peak higher (P <0.001, P <0.001), load rate change smaller <0.001). However, no occurrence ( p > 0.05), stage, lower than = 0.021). 2) results showed significant maximum signal power as well corresponding main found. types, < 0.001, 0.002, 0.004). Once speed controlled, only which may related their rigidity. walking period domain, suggesting there function various parts foot.
