PURPOSE: To compare the effects of vastus medialis oblique (VMO) motor control retraining (MCR) and quadriceps strengthening (QS) exercises on the onset timing of the medial (VMO) and lateral (vastus lateralis, VL) quadriceps muscle. METHODS: This single-blind randomized controlled trial involved 60 currently pain-free individuals with a history of anterior knee pain and delayed (>10 ms) onset of VMO relative to VL during stair stepping. A blinded assessor took measures at baseline, immediately after 6 wk of treatment, and after an 8-wk follow-up. Both exercise programs involved weekly individual physiotherapy sessions with home exercises. The MCR program comprised specific VMO exercises inc..View full abstract
