Change in Swing Phase Hip, Knee, and Ankle Flexion After Treatment. Panel (A). Pre-Treatment, Mid-Swing Gait Dyscoordination. At mid-swing, hip and knee flexion are absent, and the ankle is slightly plantar-flexed. The right plantar surface is sliding across the floor in order to bring the right limb at least up to the left stance limb. Panel (B). Post-Treatment, Mid-Swing Improved Hip, Knee, and Ankle Flexion. At mid-swing, the right hip, knee, and ankle are flexed, which is necessary in order for the right limb to clear the floor during swing phase (with permission, Stroke 2006, Daly et al. [47]).
