Fig. 6 — Estimated (a) step time, (b) stride time and (c) step count of iTUG task for CON_Health and PD_LSVT subjects at each stage of therapy. PD_LSVT subjects developed significantly faster step (p < 0.001), stride (p < 0.001), swing (p < 0.001), and double stance times (p < 0.004) following therapy. In addition to temporal gait parameters, significant reductions were observed in step count following therapy (p < 0.011) indicative of longer step lengths. Black horizontal lines represent the mean of all PD_LSVT subjects at each stage of therapy. (* p < 0.05 compared to baseline - Pre1; † p < 0.05 compared to CON_Health)
