ABSTRACT

Background: Muscular flexibility is an important aspect of normal human function. The hamstring muscles are most commonly having decreased flexibility. BFRT is a technique used to help improve muscle strength and recovery that involves using cuff to partially restrict blood flow to the affected muscle while exercising. Aim is to find the effectiveness of Blood flow restriction therapy (BFRT), stretching and combination (BFRT + stretching) for improving hamstring flexibility. Method: This was a double-blinded randomized controlled trial (RCT). Students with hamstring tightness were recruited from the university campus. Thirty-three students were randomly and equally divided into Group A (BFRT), Group B (stretching), and Group C (combined). Hamstring tightness was measured at baseline and immediately after theintervention, using active knee extension and the sit-and-reach test. The data were analyzed with ANOVA. Result & conclusion: All the three groups showed significant p value of <0.01 in within group. It can be concluded from the study that passive stretching and BFRT were effective to release hamstring tightness. But combined was more effective than BFRT, stretching. Clinical Implication: To release the tightness of muscle, agonist should be relax and antagonist muscle should be strengthened. This study focuses on the immediate effect of combination of passive stretching and BFRT on hamstring tightness. Keywords: Blood flow restrictions therapy, Hamstring tightness, stretching, active knee extension test
