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

Figure 4

Joint motion difference of the talocrural and subtalar joints during the stance phase of walking. Heel strike to midstance: (a) talocrural joint rotation (°); (b) talocrural joint displacement (mm); (c) subtalar joint rotation (°); (d) subtalar joint displacement (mm); Midstance to Toe-off: (e) talocrural joint rotation (°); (f) talocrural joint displacement (mm); (g) subtalar joint rotation (°); (h) subtalar joint displacement (mm). 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 ( means P <0.001, means P <0.01, and means P <0.05).
