Added weight doesn't effect roll-over characteristics of walking

This study investigates the effects of added weight on roll-over characteristics of walking. Ten participants without physical impairment walked with added weight equally distributed about the torso in a harness.


At each weight level, the participants walked at slow, normal, and fast self-selected walking speeds. Investigators examined roll-over characteristics by determining the ankle-foot and knee-ankle-foot roll-over shapes.


The roll-over shapes of the ankle-foot and knee-ankle-foot systems did not change appreciably with added weight at any of the three walking speeds.

The response of the lower limbs of persons without physical impairment to added weight should be considered an important design feature for prostheses and orthoses.
