Clinical Trial Summary

1. Comparison between Mulligan traction straight leg raise (TSLR) and Post Isometric Relaxation (PIR) on hamstring, on range of motion (ROM) of knee extension and flexibility of hamstring muscle.

2. Secondary objective of the study is to compare the effectiveness of Mulligan Traction Straight Leg Raise (TSLR) and Post Isometric Relaxation (PIR) in lumber spine mobility in healthy individuals.

3. This study will also help to reduce the financial burden of society by identifying the commonly neglected hamstring tightness as one of the causes of developing low back pain and eventually affecting their health.

4. This study will provide evidence regarding prevention of low back pain as hamstring tightness is one of the risk factor for developing low back pain.

Description:

Hamstring is the common muscle which undergoes adaptive shortening when compared with other group of muscles. Hamstrings refer to the three posterior thigh muscles and its action includes hip extension and knee flexion. Limited muscle extensibility is a common problem that affects various patient populations as well as healthy individuals. The ability of an individual to move smoothly depends on his flexibility, an attribute that enhances both safety and optimal physical activities. Flexibility is an important physiological component of physical fitness, and reduced flexibility can cause inefficiency in the workplace and is also a risk factor for low back pain. Muscle extensibility is an essential element of biomechanical function. Flexibility has been defined as the ability of a muscle to lengthen and allows one joint (or more than one joint in a series) to move through a range of motion and is an essential component of normal biomechanical functioning.

The flexibility of hamstring muscle is important for general and athletic population and of almost importance for health care professionals, to achieve this goal one needs to know the most effective and efficient technique to gain hamstring flexibility. Lack of hamstring muscles extensibility conditions decrease the pelvic mobility. This invariably leads to biomechanical changes in the pressure distribution of the spine and consequent spinal disorders. Therefore, poor hamstring extensibility has been associated with thoracic hyper kyphosis , spondylolysis , disc herniation changes in lumbopelvic rhythm and low back pain. Hamstring tightness is also associated with low back and lower extremity musculoskeletal disorders leading to biomechanical changes of the pelvis and low back. The literature reports a number of associated benefits of flexibility including improved athletic performance, reduced injury risk, prevention or reduction of post-exercise soreness, and improved coordination.

Stretching techniques are the treatments used to improve muscular extensibility to improve range of motion (ROM), and can help prevent damage in daily life or sports, reduce muscle pain, and improve muscle capability. There are various treatment for the hamstring stretching like active release technique, passive stretching, static stretching, Proprioceptive neuromuscular facilitation Stretching Techniques, eccentric stretching exercises for improving hamstring flexibility.

Mulligan performs mobilization procedures while patients were moving, either actively or passively, or while they were performing a resisted muscle contraction .Indications for use of Mulligan's Traction Straight Leg Raise (TSLR) technique are limited range of motion of hip flexion together with low back pain with or without referred leg pain. The intention of this technique is to restore normal mobility. It stretches the lower extremity muscles in combination of hamstring, adductors and rotators. The Traction Straight Leg Raise technique is painless intervention that is said to have immediate benefits.

Muscle energy technique (MET) is a procedure that involves voluntary contraction of a patient's muscle in a precisely controlled direction, at varying levels of intensity. It is unique in its application as the patient provides the initial effort while the practitioner facilitates the process. The benefits of muscle energy techniques (MET) include: Restoring normal tone in hypertonic muscles, strengthening weak muscles, preparing the muscle for subsequent stretching, improved joint mobility. It includes two techniques post isometric relaxation technique and reciprocal inhibition.

According to a study muscle energy technique (post isometric relaxation technique - PIR) is more effective than ultrasound therapy with active static stretching and passive static stretching in improving the hamstring flexibility in individuals with hamstring tightness.A study compared two muscle energy techniques (MET with 30-s post isometric stretch phase vs MET with 3-s post-isometric stretch phase) for increasing flexibility of the hamstring muscle group and concluded that both techniques appeared to be equally effective in increasing hamstring extensibility. The findings suggest that altering the duration of the passive stretch component does not have a significant impact on the efficacy of MET for short-term increase in muscle extensibility.

According to a study Mulligan traction straight leg raise technique is significantly effective in increasing straight leg raise (SLR) range of movement .A study demonstrated that both Mulligan traction straight leg raise (TSLR) and MET are effective in improving Knee range of motion (ROM) in subject with tight hamstring. The study showed that MET is significantly better then Mulligan traction straight leg raise (TSLR).The Effects of Hold-Relax Technique and Mulligan's Straight Leg Raise with Traction Technique on Flexibility of Shortened Hamstring was studied and concluded that both Mulligan's straight leg raise with traction technique and hold-relax technique show immediately. Although Mulligan's straight leg raise with traction technique was more increased average extension angle of knee joint at 90-90 straight leg raise test than the hold-relax technique.A study compared immediate effects of traction straight leg and bent leg raise on hamstring muscle flexibility in normal individuals and concluded that Mulligan's traction straight leg raise technique was more effective in improving hamstring flexibility.

Intervention

Other:
• Mulligan Traction Straight Leg Raise (TSLR)
The patient was in a supine position on a low bed and the therapist faced the limb of the patient that was to be treated. The therapist grasped the lower leg of the patient just near the ankle and raises the leg off the bed to a position just above the painful range. The therapist flexes the knees. Traction was retained as far as possible with a straight leg lift if there was no pain. The pain-free traction straight leg raise range was administered for 10 second and the procedure was repeated three times.
• Post Isometric Relaxation technique (PIR):
The knee of the affected leg was extended, and the affected hip was flexed. Then the calf of the patient was placed on the shoulder of therapist. The therapist was standing on the side of the affected leg. The flexion of the hip was performed on the affected leg until resistance was felt. The patient was asked to gently push down on the therapist's shoulder with the leg. The therapist resisted hip extension to create an isometric contraction. The duration of the contraction was 10 seconds. Then the patient was instructed to relax and the therapist gently flexed the hip until the next barrier was felt. The technique was repeated three times.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Active Knee Extension test (Popliteal angle):	Position the extremity which is being tested in hip 90 degrees of flexion,0 degrees of abduction, adduction, and rotation.The knee that is being tested is relaxed in flexion.The opposite limb will rest on the examining table with the knee positioned in full extension and the hip in 0 degrees of extension, flexion, adduction abduction, and rotation. Stabilize the femur to maintain the hip in 90 degrees of flexion and to avoid unnecessary movement at hip joint. Extend the knee to the end point when resistance is felt from development of tension in the posterior thigh muscles and upon further knee extension causes the hip extension. Measurement of knee ROM the landmarks are greater trochanter, lateral condyle of femur and the lateral malleolus. On lateral condyle of femur the fulcrum of the goniometer will be placed, the proximal arm fixed along the femur using greater trochanter as reference.The distal arm will be aligned with the lower leg using the lateral malleolus as reference.	for two weeks
Primary	Modified Modified Schober's Technique for lumber flexion:	The investigator knelt behind standing patient and marked the Posterior superior iliac spine by labeling with her thumbs the inferior margins of the Posterior superior iliac spine of the subject. Along the midline of the lumbar spines horizontal to the Posterior superior iliac spine ,an ink mark was drawn.15 cm above the original mark, another ink mark was made. Between the skin markings, the tape measure was then lined up. The therapist instructed the subject to bend forward with the tape measure firmly pressed against the skin of the subject, and while holding the tape measure with his or her fingertips. The new distance between the superior and inferior skin markings was measured when the subject bent forward into complete lumbar flexion. After trunk flexion, the distance between these marks was measured and the change in the gap between the marks was used to demonstrate the amount of lumbar flexion. All skin marks were cleaned using rubbing alcohol after each measurement.	for two weeks
