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

Figure 3 Comparison of clinical assessment parameters within group (between pre- and post-treatment) and among groups (between lower body positive pressure group and control group). A: Western Ontario and McMaster Universities Index (scores); B: Activity of daily living (scores); C: Visual analogue scale (scores); D: Keen active joint range of motion flex-extension (degrees). ^b0.001 ≤ P < 0.01, ^cP < 0.001. LBPP: Lower body positive pressure; WOMAC: Western Ontario and McMaster Universities Index; VAS: Visual analogue scale; AROM: Active joint range of motion; ADL: Activity of daily living.
