The body weight support (BWS) system that allows a patient to support his or her body weight in step-wise fashion, depending on their physical condition, is an important intervention that assists individuals with gait disabilities in their gait rehabilitation. In this paper, we measured human body signals in order to verify a rehabilitation system using active harness that we developed for gait and balance training based on ceiling-rail platform. 20 healthy participants were performed to conduct daily activities related to lower limbs. They did a kind of motions related to daily life (Normal Walking, Stand-to-Sit, and Stair Walking Down) according to variation of body weight support rates (0%, 30%, 50% of subject’s body weight). The effectiveness of the weight supporting on healthy people is analyzed by the muscular activities and foot pressure distribution. In normal walking, the decrease of fore-foot pressure, lateral soleus muscle and biceps femoris muscle were remarkable. The result of stand-to-sit results motion indicated that the rearfoot pressure and tibialis anterior muscle activities exceptionally decreased according to body weight support. The stair walking down results indicate the marked drop of fore-foot pressure and rectus femoris muscle activities. Based on these results, a function of weight supporting is very helpful to improve the gait ability of people with gait disorder.
