Figure 6
Ankle joint angle. (A) Ankle joint angle across the stride phase (ankle angle of 0° equals anatomic position) for the curved treadmill (black lines) and flat treadmill (gray lines) at 0.67 m/s (solid lines), 1.12 m/s (short dashed lines) and 1.56 m/s (long dashed lines). (B–D) SPM trajectory (solid lines) across the stride phase for treadmill (B), speed (C) and interaction (D) effects. The dashed line indicates level of significance of 5%. SPM trajectory above the dashed line indicates a significant effect of the ankle angle.
