Key Rotation: ankle joint angle in lunge. Max-PS the maximum principal stress peak difference at the medial and lateral sesamoid in the trail foot in lunge; Min-PS the minimum principal stress peak difference at the medial and lateral sesamoid in the trail foot in lunge. Total stress: the TS difference between the medial and lateral sesamoids in the trail foot in lunge
