Fig. 2

Results of the three-dimensional foot analysis (tibiotalar dorsiflexion, dorsiplantar flexion, and medial arch angle) are shown during the stance and swing phases of the gait cycle as averaged curves of the feet. Red depicts the decreased tibiotalar dorsiflexion group, blue the increased tibiotalar dorsiflexion group, and green the group with tibiotalar dorsiflexion within 1 standard deviation (SD) of the norm (grey)). Each solid line represents the mean, while the dotted lines represent 1 SD above or below the mean. The range for twenty-six normal feet is represented by the grey shading
