Variations in the stiffness of the MG, MG fascia, LG, LG fascia, SOL, SOL fascia and PF at –50° (blue), 0° (red), and 25° (green) of ankle joint flexion with the knee fully extended/flexed to 90°. (A,B) The knee fully extended, (C,D) the knee flexed to 90°. *Comparisons were carried out between any two groups, and all P values were less than 0.05. **Comparisons were carried out between any two groups, and all P values were less than 0.001. NS (nonsignificant) Comparisons were carried out between any two groups, and all P values were greater than 0.05. M: muscle, F: fascia.
