Figure 1From: A novel walking speed estimation scheme and its application to treadmill control for gait rehabilitationFoot velocities along the forward walking direction during overground and treadmill walking. The swing foot velocities are similar during overground and treadmill walking. Foot velocity during stance phase is zero in overground walking (Figure1(a)) and negative on a treadmill, since it is caused by the treadmill speed (Figure1(b)). It should be noted that magnitudes of sinusoidal trajectories in both cases are equal. (a) Foot and pelvis velocities (Overground) (b) Foot and pelvic velocities (Treadmill).Back to article page
