The role of quadriceps exercise in the treatment of patellofemoral pain syndrome

In recent years there has been increased interest in the role of exercise in the alleviation of patellofemoral pain syndrome; Contradictions which result in a lack of a consensus amongst clinicians and researchers as to the most beneficial type of exercise are reviewed. The popularly held belief that there are imbalances between some components of the quadriceps femoris is also reviewed and conflicting evidence that quadriceps contractions can be enhanced by altering hip and knee positions is found. Some traditional exercises, previously considered essential to any regime for this common condition, were not found to be as beneficial as previously thought, Consequently, some of these exercises should be less prominent in a rehabilitation programme for patellofemoral pain syndrome.
