Abstract

The purpose of this study was to investigate effect of feedback methods and ambulatory assistive aids on accuracy of partial weight bearing in healthy adults. Twenty subjects were recruited and trained to 30% weight bearing of body weight (BW) using 3-point gait crutches and wheeled walker pattern. Dynamic feedback group (n=11) was received dynamic postresponse feedback and static group (n=9) received static feedback. Force plate was used to measure %BW and GAITRite used to measure gait parameters in immediately and after 3 days of training. Immediately after training, there was not significantly at 30%BW target load in dynamic group with crutch gait (p>.05). There were significantly differences in %BW according to feedback methods and ambulatory aids (p<.05). There was not significant difference between immediately and after 3 days of training (p>0.05). There were significantly differences in gait velocity and stance ratio between crutches and wheeled walker gait (p<.05). Thus, it was suggested that if possible, use crutches, training for partial weight bearing via dynamic feedback is necessary.
