title: The efficacy of an integrated neuromuscular inhibition technique on upper trapezius trigger points in subjects with non-specific neck pain: a randomized controlled trial.
abstract: Currently, large levels of practice variability exist regarding the clinical deactivation of trigger points. Manual physical therapy has been identified as a potential means of resolving active trigger points; however, to date the ideal treatment approach has yet to be elucidated. The purpose of this clinical trial was to compare the effects of two manual treatment regimens on individuals with upper trapezius trigger points. Sixty patients, 19-38 years of age with non-specific neck pain and upper trapezius trigger points, were randomized into one of two, 4 week physical therapy programs. One group received muscle energy techniques while the second group received an integrated neuromuscular inhibition technique (INIT) consisting of muscle energy techniques, ischemic compression, and strain-counterstrain (SCS). Outcomes including a visual analog pain scale (VAS), the neck disability index (NDI), and lateral cervical flexion range of motion (ROM) were collected at baseline, 2 and 4 weeks after the initiation of therapy. Results revealed large pre-post-effect sizes within the INIT group (Cohen's d  =  0.97, 0.94 and 0.97). Additionally, significantly greater improvements in pain and neck disability and lateral cervical flexion ROM were detected in favor of the INIT group (0.29-0.57, 0.57-1.12 and 0.29-0.57) at a 95% CI respectively. The findings of this study indicate the potential benefit of an integrated approach in deactivating upper trapezius trigger points. Further research should be performed to investigate the long-term benefits of the current treatment approach.
