Critical appraisal of disability in patients with chronic patellofemoral pain syndrome (PFPS): A randomised control trial of VMO selective training versus general quadriceps strengthening

Patellofemoral pain syndrome is a common condition that can be caused by multiple factors and can affect quality of life. Rehabilitation involves strengthening of the quadriceps but there is debate about if treatment should focus on being selective to the vastus medialis component of quadriceps. The following is a critical appraisal of a study which investigates if selective strengthening is more beneficial than general strengthening.
