Effect of a Semirigid Ankle Brace on the In Vivo Kinematics of Patients with Functional Ankle Instability during the Stance Phase of Walking

Figure 3

The 6DOF mean joint positions of the talocrural (a) and subtalar (b) joints during the seven poses of the stance phase. DF+/PF-, dorsiflexion/plantarflexion; EV+/IV-, eversion/inversion; ER+/IR-, external rotation+/internal rotation-; A+/P-, anterior/posterior displacement; L+/M-, lateral/medial displacement; P+/D-, proximal/distal displacement. The error bars were standard deviations ( (red), comparison between FAI without brace and control; (blue), comparison between FAI with brace and control; (green), comparison between FAI without brace and FAI with brace; means P <0.001, means P <0.01, and means P <0.05).
