highly significantp < 0.001
Group comparisons between TFC subgroups (early, moderate, advanced) revealed highly significant differences in stride time CV ( p < 0.001, d = 1.601), stance time CV ( p = 0.002, d = 1.214), swing time CV ( p = 0.001, d = 1.347), stride length CV ( p = 0.010, d = 0.935), and gait velocity CV ( p < 0.000, d = 1.613).
