Effects of added inertia and body weight support on lateral balance control during walking

Abstract

A robot-driven gait orthosis which allows balance training during gait would further enhance the capabilities of robotic treadmill training in gait rehabilitation. In this paper, additional mass is attached to walking able-bodied subjects to simulate the effects of additional inertia and body weight support on the lateral balance task. The combination of additional inertia and body weight support led to reduced step widths, suggesting a stabilising effect which may reduce the challenge of the lateral balance task.
