Effect of VMO Strengthening on Pain, Strength and Function in Subjects with Patellofemoral Pain Syndrome: An Experimental Study
Journal Title: Journal of Medical Science And clinical Research - Year 2014, Vol 2, Issue 9
Abstract
The objective of this randomized controlled trial was to evaluate the effect of “SQUAT ADD” exercises in patellofemoral pain syndrome in terms of pain, strength and functional ability with and without biofeedback. Twenty five subjects were recruited for the study on the basis of inclusion and exclusion criteria after signing the informed consent form. They were randomly assigned to two groups with 13 subjects in Group A and 12 subjects in Group B. Subjects of both the group were first administered by Squat add exercise for 2 sets along with 3 repetition with 6 sec of cuff hold time in between 10 sec of rest in each repetition with and without biofeedback. Numeric pain scale was used to measure pain, kujala questionnaire was used to measure functional ability, and VMO strength was measured by SQUAT-ADD. The within group comparisons at the end of the trial showed significant improvement. The between-group comparisons at the end of the trial showed significant improvement in function only. The result of present study indicates that SQUAT ADD exercise improved the quality of life as well as strengthening of VMO leads to decrease pain in subjects with PFPS. The present study concluded that SQUAT ADD exercise showed reduction in pain, increase in functional ability and increase in muscle strength of subjects with PFPS. The benefit of biofeedback although remains unclear.
