Figure 3. Comparison of mean hip and knee flexion angles for each heel-drop exercise. “Plantar” and “Dorsi” refer to when the ankle was at peak plantarflexion (start of the cycle) and peak dorsiflexion (end of the cycle) respectively. Positive values correspond to adduction and hip flexion and knee extension. * denotes statistically significant differences. For definitions of each exercise, the reader is directed to Table 1.
