Spatiotemporal measures and variability before and after eight home-based gait training sessions cued with rhythmic auditory stimuli (N = 11).
| Gait measure | Baseline median value (IQ range) | Retest median value (IQ range) | Change in median value (IQ range) | Wilcoxon signed rank test | Effect size (r = z/√N) |
