Core Tip

Core Tip: To our best knowledge, this is the first randomized controlled trial focusing on lower body positive pressure (LBPP) training in knee osteoarthritis rehabilitation. Both subjective clinical assessment and objective biomechanical assessments were used in this study. The LBPP group showed more improvements in pain relief and gait improvement than the conventional group. LBPP treadmill exercise training could be considered an effective approach for patients with knee osteoarthritis.
