Before revision:  Here, we observe walking for short distances and walking in circles in subjects with unilateral lower-limb amputation using a Jaipur Foot prosthetic leg. We find that the preferred walking speeds are lower for unilateral amputees for short distances , but the distance-dependence of preferred walking speed is less steep than for non-amputees.
After revision:  Here, we observe walking for short distances and walking in circles in subjects with unilateral lower-limb amputees wearing an above or below-knee passive prosthesis, specifically, a Jaipur foot prosthesis. Analogous to earlier results in non-amputees, we found that their preferred walking speeds are lower for unilateral amputees for short distances , but the distance-dependence of preferred walking speed is less steep than for non-amputees.
