Effects of lower body positive pressure treadmill on functional improvement in knee osteoarthritis: A randomized clinical trial study

Figure 4 Comparison of spatiotemporal parameters within group (between pre- and post-treatment) and among groups (between lower body positive pressure group and control group). A: Stance phase in gait cycle (%); B: Swing phase in gait cycle (%); C: Mean velocity (%height/s); D: Cadence (steps/min); E: Stride length (%height); F: Step width (m). ^a0.01 ≤ P < 0.05, ^b0.001 ≤ P < 0.01, and ^cP < 0.001. LBPP: Lower body positive pressure.
