About this trial
The hamstring tightness is considered as the inability to achieve knee extension greater than 160 degrees while hip is flexed at 90 degrees. When low back pain (LBP) persists for 12 weeks or longer, it is termed as chronic low back pain. The objective of study is to see the effect of dry needling versus soft tissue mobilization on hamstring muscle on pain, range of motion and functionality in patients with chronic low back pain.

Treatments tested in this trial
Dry Needling
Other interventionBaseline Treatment: Hot pack will be applied for 15 minutes on Hamstrings and lower back and transcutaneous electrical nerve stimulation (TENS) at lower back for warm up and pain relief to both groups. Then spinal mobilization (Poster lateral glide) of grade 1 and 2 (3 sets of 6 repetitions) i.e. within the spine resistance. Dry Needling will be given to group A along with baseline treatment through following protocol: Patient will be in prone lying. Sterilized disposable dry needles of 0.25\*60mm will be used. Dry needling will be performed on three points on Hamstring muscle for one minute each. We considered a line between ischial tuberosity and head of fibula to target long head of bicep femoris (60% of line) and short head of bicep femoris (30% of line). Semitendinosus and Semi Membranosus were targeted at a point of 60% of line from ischial tuberosity to medial epicondyl of femur. Sessions: Total 8 sessions will be given 2 sessions per week for 4 weeks.
Soft Tissue Mobilization
Other interventionBaseline Treatment: Hot pack will be applied for 15 minutes on Hamstrings and lower back and transcutaneous electrical nerve stimulation (TENS) at lower back for warm up and pain relief to both groups. Then spinal mobilization (Poster lateral glide) of grade 1 and 2 (3 sets of 6 repetitions) i.e. within the spine resistance. Soft Tissue Mobilization will be given to Group B along with Baseline treatment. Subject will be in prone lying position with knee bent at 30 to 60 degrees. Soft tissue mobilization will be applied on hamstring muscle through Graston technique. Massage cream will be applied on hamstring muscle and Graston Instrument will be rubbed from gluteal line to politeal fossa 30 times for 60 seconds. Sessions: Total 8 sessions will be given 2 sessions per week for 4 weeks.

Primary outcomes

Numeric Pain Rating Scale
Numeric Pain Rating Scale (NPRS) was used to measure low back pain. NPRS consists of 11 points, which range from 0= no pain, 1-4= mild pain, 4-7= moderate pain 7-10= severe pain . Researchers states that NPRS shows High test to re test reliability (ICC 0.96) in elderly populations with musculoskeletal disorders without having cognitive dysfunction.

4 weeks2
Oswestry Disability index (Urdu)
The Oswestry Disability index (ODI) consists of 10 patient- completed questions in which the response options are presented as 6-point Likert scales. Scores range from 0% (no disability) to 100% (most severe disability).
Time frame
4 weeks3
Inclinometer
It was used to measure range of motion of low back. An instrument for measuring angles is an inclinometer. A sensor is housed in the housing of an inclinometer. The sensor measures the housing's tilt and is sensitive to gravity. After that, the angle is shown on a dial or digital display.

Active Knee Extension Test
The most effective way to exclude the hamstring muscle's extensibility range, with the hip fixed at a 90-degree angle and precise instrument placement, is to perform the active knee extension test. This technique provides accurate measures of hamstring length and extensibility when used in a supine 90/90 position. Both a normal goniometer and an electrogoniometer were used to measure the amount of extension. Whether hamstring tightness contributes to mechanical low back pain can be inferred from this result.
