Objective: The objective of the study was to examine the effect of integrated neuromuscular inhibition technique (INIT) in the treatment of MTrP of upper trapezius using pressure pain threshold (PPT) and visual analog scale (VAS). Method: Fifteen participants who came to manipal hospital, eight of them were randomized into INIT group and seven of them were randomized into conventional group. Two outcome measures were 1) Pain Pressure Threshold (PPT) and 2)Visual Analogue Scale (VAS) taken at baseline and after 2 weeks. Results: When PPT was compared between the group there was no significant change demonstrated, the mean change score between the group was 1.33 lbf/cm2 (p-value>0.05) but the mean change score of VAS between the group was 14.61 mm (p-value<0.05), there was a significant improvement in VAS observed between the group. Conclusion: INIT is effective in relieving pain in participants with upper trapezius MTrP.
