Effectiveness of Myofascial Release with Foam Roller Versus Static Stretching in Healthy Individuals with Hip Adductor Tightness: A Randomized Clinical Trial

Journal Name:

Publication Year:

Abstract (2. Language): 
Background: Hip adductors are a group of muscles that stabilize the pelvis during weight transfer in lower limbs in a gait cycle. This muscle group commonly goes into tightness as the full available range of motion is scarcely used which in turn may be a predisposing factor in the development of knee and low back pain. Aim: Traditional method of static stretching has proved to be effective in reducing tightness. Foam roller is an upcoming method used for stretching of various muscle groups which has shown superior results. The aim of the study was to compare the treatment methods. Methods: Thirty young healthy individuals were selected after screening for bilateral hip adductor tightness using smartphone inclinometer for hip abduction range of motion. They were randomized to either the foam roller or static stretching group. Subjects attended a baseline session, followed by 5 days intervention, and reassessment on the 5th day post intervention. Outcome measures used were hip abduction range of motion using smartphone inclinometer, single leg hop test and 8 direction star excursion balance test for dynamic postural stability. Results: Both the groups showed significant improvements in hip abduction range of motion, single leg hop test and SEBT. When compared, the foam roller group showed marginally better results than static stretching. The results also showed significant prepost differences within the respective groups. Conclusion: Treatments have shown significant results in both groups however, myofascial release with foam roller has proved to be marginally more effective than static stretching in releasing hip adductor tightness, increasing hip abduction range of motion and improving dynamic balance.
