Immediate effects of foot orthoses on gait biomechanics in individuals with persistent patellofemoral pain

The efficacy of foot orthoses in reducing patellofemoral pain (PFP) is well documented; however, the mechanisms by which foot orthoses modulate pain and function are poorly understood. This within-subject study investigated the immediate effects of foot orthoses on lower limb kinematics and angular impulses during level walking and stair ambulation in individuals with persistent PFP. Forty-two participants with persistent PFP (≥3 months...
