Mulligan Stretch With Traction Versus Post Isometric Relaxtion on Hamstring Flexibility

INTRODUCTION:

Mobility in human gait depends on flexibility of hamstring muscles. Hamstring muscles function is hip extension and knee flexion. In most of the population, tightness or shortening of hamstring muscles occur which limits hip flexion. To measure hamstring muscles flexibility simple passive SLR is performed and range is recorded by manual goniometer. To increase SLR, several techniques are used: MET's and TSLR. Effectiveness of these techniques depend on muscle flexibility.

OBJECTIVE:

The purpose of this study is to compare the effectiveness of mulligan stretch with traction technique and muscle energy technique to increase the SLR in athletes with hamstring tightness.

METHOD:

The data will be collected from Athletes in sports clubs, gyms, and sports fields of Lahore. The study will be completed in a period of six months after the approval of synopsis. The design of my study will be Randomized Control Trial (RCT) study. And the sampling technique will be non-probability convenience sampling. A sample of 32 (16 in each group) has been selected using 10% level of significance and 80% power of test.

Three groups will be made each containing 16 participants with inclusion criteria met. Group A will be given control group treatment with Muscle Energy Technique applied over the period of 4 weeks. Group B will be given control group treatment with Mulligan Stretch with Traction Technique applied over the period of 4 weeks.

Total 3 recordings of Hip Flexion ROMs shall be taken with manual goniometry as follows initial/first day, 3rd week, final week/last treatment. A sum of 8 treatments shall be given to the intervention group over the period of 4 weeks, 2 treatments per week.

Inclusion criteria

• Both male and female
• Negative Spring test
• Asymptomatic
• SLR < 80⸰

Exclusion criteria

• Positive LBP
• Lumbar Straightening
