Scaling and retention. a Indicates the change in fall percentage from pre-training to post-training and after 3 weeks of retest trials. Both groups demonstrated a significant reduction in the fall outcome from pre-training to retest trials. b Demonstrates the change in the number of compensatory steps taken. c Demonstrates the change in stability at touchdown. There was a significant scaling and retention effect noted in the stability of both the HFHI and LFLI groups. *, indicates a significant main effect of trial, and # indicates a significant main effect of group
