Brief summary
The study will be randomized controlled trial to determine the effects of lumbosacral mobility program on muscle length in sedentary young adults with tight hamstrings. Only the eligible subjects who fulfill the inclusion criteria will be included in the study. A sample of 78 subjects will be taken and randomly allocated into two groups with 39 each. Group A will be given three treatments. Manual therapy, mobility exercise therapy and home based self stretching program. Manual therapy mobilization posterior-anterior glides at lumber facets joints, transverse glides at spinous process & Posterior-anterior glides at SI joint. Glides will be performed 3 times with 5 repetitions. Mobility exercise therapy (Single knee to chest, double knee to chest, Lumbar rotation, Lumbar extension, Pelvic tilting). A total of 30 min sessions three times a week on alternate days for 1 week & home-based self-stretches program twice a day for three times a week on alternate days for 1 week. Group B will be given home-based self-stretching program twice a day for three times a week on alternate days for 1 week .The baseline values of all the dependent variable will be recorded on day one and at the end of the 1-week treatment session, using goniometry, active and passive knee extension test, passive straight leg raising and lower extremity functional scale will be used
Detailed description
The hamstring muscle group consists of four muscles (semitendinosus, semimembranosus, biceps femoris long head, biceps femoris short head). It's a two-joint muscle working simultaneously to act as a hip extensor and knee flexor. It also functions to maintain the stability of the knee joint. The hamstring plays important role in daily activities like running & walking. A lot of factors affecting hamstring function, one of them is flexibility, it is defined as the extent to which muscle length contributes to maximal joint range of motion. It is a well-known muscle of has a shortening tendency. There are many methods for treating hamstrings flexibility/tightness/shortening. Routinely, physiotherapists are using stretching & strengthening exercises, instruments assisted in soft tissue mobilization. The current study focuses on two treatments manual therapy & lumber mobility exercises
Interventions
OTHERLumbosacral manual therapy mobilization, lumber mobility exercises and home based self strechings program.
Manual therapy, mobility exercise therapy and a home-based self-stretching program. Manual mobilization postero-anterior glides at lumber facets joints, Transverse glides at spinous process & Posterior-anterior glides at SI joint. Glides will be performed 3 times with 5 repetitions. Mobility exercise therapy.
OTHERhome based self strechings program only.
Home based self-stretching program includes 3 repetitions of 15 seconds duration stretch (with 20 seconds rest between each repetition). Repeat stretching exercises twice a day for 3 alternate days for 1 week. Piriformis stretch: in supine crook lying, placing the lateral side of the foot over the contralateral knee and pulling towards the chest with the hands. Quadriceps stretch: stand on your left leg, one knee touching the other, hold a chair or the wall to keep you steady if needed, grab your right foot, using your right hand, and pull it towards your butt. Hamstring stretch: To stretch the right leg, sit on the ground with the left leg bent at the knee with the foot facing inward. This is called the butterfly position. Extend the right leg, keeping it slightly bent at the knee. Bend forward at the waist, making sure to keep the back straight.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Active knee extension test | 1 Week | A reliable tool for hamstring length measurement. Subject is in supine lying position on examination table while other leg is in extension position stabilized with two strap. One across midthigh and other across pelvis ( to prevent compensatory movements ) subject were asked to extens the knee until stretch sensation felt ayt posterior aspect of thigh. Note the range with goniometer |
| Passive knee extension test | 1 Week | A reliable tool for hamstring length measurement. Subject is in supine lying position on examination table while other leg is in extension position stabilized with two strap. One across midthigh and other across pelvis ( to prevent compensatory movements ) now passively extend subject's knee until stretch sensation felt at posterior aspect of thigh. Note the range with goniometer. |
| Goniometry | 1 Week | It is an affordable & available tool for measurement of joint range of motion in degrees. (18) Passive Straight Leg Raise (SLR) test Subject is asked to maintain a position of supine lying on examination bed. Then passive SLR is performed by lifting subject heel. ( knee remains in extension ) pelvis should remain stabilize. look for the point at which discomfort starts. Note the range. |
| LEFS | 1 Week | It is well known validated tool used to assess the functioning of lower extremity. It's a 20 question test which further subgroups into 4. Questions based on physical activity of lower extremity |
