Due to high incidence of low back pain in our society, P.S frequently goes unrecognized or misdiagnosed in clinical settings. Method: Patients with piriformis syndrome were screened for inclusion and exclusion criteria after detailed assessment. 30 patients who meet the inclusion criteria were grouped into 2groups (15 patients in each group). Control group received UST and piriformis muscle stretching and experimental group received MET with DFM. Treatment period was about 30-40min each session in regular period of 6 days for a week for both groups. Outcome Measures: Oswestry Disability Index, Visual Analogue Scale, Standard Goniometer Results: Statistical analysis of intergroup significance by Mann Whitney U-test for IR ROM (sig.0.000 < p = 0.05) and independent sample t-test for VAS (t = 2.895 > table value, t = 2.048) and ODI (t = 4.842 > table value, t = 2.048) reveals that experimental group shows significant difference between pre test and post test values of IR ROM, VAS and ODI than that in the control group. Conclusion: experimental group who received MET along with DFM shows greater improvement on pain, disability and IR ROM in individuals with piriformis syndrome than those in the control group who received U.S.T and piriformis muscle stretching.

Several studies reported physical therapy modalities Piriformis syndrome (PS) is a painful musculoskeletal such as heat therapy, cold therapy, and ultrasound condition, characterized by a constellation of symptoms therapy along with stretching of the Piriformis muscle that include buttock or hip pain. There are two types have a beneficial effect on treatment. Also manual of P.S: Primary P.S is caused by an anatomic variation therapy approach may combine muscle stretches, muscle like split Piriformis muscle, split sciatic nerve etc.The energy techniques, soft tissue and myofascial techniques Secondary P.S, caused by precipitating factors such to address all somatic dysfunctions in the patients with as macrotrauma,local ischemia, microtrauma due to Piriformis syndrome. overuse or direct compression (e.g.: wallet neuritis)etc5.

A degree of subjects are selected by the proper screening and compression was applied via the elbow for 5-7secs while fulfilling the inclusive and exclusive criteria. The control the muscle is kept at a reasonable but not excessive group received U.S.T and piriformis muscle stretching degree of stretch.

Both bringing the lower leg towards external rotation against group received hot packs application for about 10min resistance. After the contraction ceases and the patient prior to muscle stretching in order to induce relaxation. relaxes, the lower limb was taken to its new resistance barrier and elbow pressure was reapplied. The procedure The outcome measures used were Oswestry was done 10times in each session. disability index to measure pain and disability, Visual Analogue Scale to measure pain intensity and standard goniometer to detect IR ROM deficit. Each measurement was done on the first day of treatment (pre test) and on the last day of the treatment (post test). Then datas were analyzed statistically. Statistical data reveals that MET along with DFM shows significant effect over standard physical therapy treatment on pain, disability and IR ROM of hip joint in individuals with P.S. According to Fred Mitchell, MET can be defined as, technique where the patient voluntarily moves body as specifically directed by the physician from a precisely controlled position, in a specific direction and against a distinctly execute
