Effect of Mulligan Stretching Techniques (TSLR AND BLR) on Biceps Femoris Muscle and Pelvic Rotation by Using Surface EMG and Bubble Inclinometer Respectively

This study was aimed to investigate and compare the effectiveness of two Mulligan techniques (TSLR and BLR that is Traction Straight Leg Raise and Bend Leg Raise) in improving the biceps femoris muscle performance, flexibility and pelvic rotation. A total of 90 asymptomatic female subjects of 18 to 30 years age were taken which were randomly divided into three groups, that is, two experimental (A and B) and one control group (C). The pelvic rotation ROM, passive straight leg raise ROM and EMG activity were checked in all three groups, after that the BLR, TSLR and Hamstring Self Stretch was provided to Group A, B and C respectively. All the previous readings were checked again. TSLR stretching technique was found to decrease the EMG activity and increase the range of pelvic rotation and passive straight leg raise more than other two groups. Conclusion: Mulligan TSLR stretch is more effective than BLR stretch in improving biceps femoris muscle performance, flexibility and pelvic rotation.
