Abstract

Background: Myofascial pain syndrome is a chronic disorder in one or more muscle group and it is related with active myofascial trigger points. Myofascial pain syndrome begins from active trigger points at muscle and fascia with symptoms including pain, tenderness, spasm, decrease ROM, weakness and some autonomic problems related to that area. Common muscle affected includes upper fibers of trapezius muscle due to repetitive micro trauma and constant burden due to its antigravity action. Objective: To compare the effect of sustain pressure and Integrated Neuromuscular Inhibition Technique on individuals with upper trapezius TrPs. Methods: The Study Design was Randomized control trial. According to inclusive criteria 26 patients were randomly allocated by sealed envelope method in experimental and control group. Patients were assessed at baseline and 4th day of session on NPRS, NDI questionnaire and ranges were taken by Goniometer and pressure threshold by Algometer. There was 3 drop out and the reason was loss of follow up. Hot pack was applied to both groups for 10mints before session. Sustain pressure was given for 3sec hold and 2sec release till pain decreases in control group. While, in experimental group INIT was used. Sustain pressure was applied on MTrPs for 3sec hold and 2sec release till pain decreases, Post isometric relaxation (MET) was given with 6-10 sec hold and repeat 4 times and at last SCS was given to hold muscle in shortest position for 90sec or pain reduced to 3 out of 10. At last cervical stretches were given and home plan was guided.  Results: Between groups the P-value was < 0.01 in terms of pain, NPRS, NDI and range of motion. The pain threshold also showed significant result (<0.01) at right and left side TrP1.While results were non-significant (>0.01) for right and left upper trapezius TrP2. Conclusion: It was concluded that INIT showed better result than Sustain pressure in management of upper trapezius trigger points in terms of pain, neck disability, pressure threshold and ROM.
