  1. Data are represented as mean ± standard deviation
  2. K/H ratio Knee separation distance divided by hip separation distance, IC Initial contact, MKF Maximum knee flexion, %MAXD Maximized reach distance
  3. *P < 0.017, significant difference after comparing with value at initial evaluation
  4. aData of Posterior Medial was not significantly different by repeated- ANOVA test, so paired t test was not performed
