Chronic Neck Pain (CNP) is also a frequent complaint in the general population. The pathogenesis of nonspecific CNP is not clear. This study aimed to assess the effects of soft tissue release, muscle energy techniques and exercise on neck Range of Motion (ROM), Neck Disability Index (NDI), and pain in patients with nonspecific CNP.<br> <strong>Methods:</strong> This is a randomized, single-blind, clinical study conducted on two groups of patients in Iran, during 2016-2017. Group A received intervention treatment and group B, as control, received no treatment for 21 days. Each group consisted of 12 participants who were selected considering inclusion and exclusion criteria. Each patient in group A received manual treatment protocols (soft tissue release and muscle energy techniques) plus exercise therapy, in six sessions, one session per day, two days a week over a period of 21 days. Clinical assessments were performed at the first and last session (before and after the treatment). Before starting the study, the reliabilities of measurement methods were evaluated and the results were acceptable. Clinical assessments included neck ROM, NDI and pain based on Visual Analogue Scale (VAS). Repeated measures ANOVA test was performed for data analysis using SPSS (version 20).<br> <strong>Results:</strong> Totally, 16 women and 8 men were participated in this study. To test the hypothesis and analysis of the study variables at regular intervals from the beginning to the end of treatment, repeated measures ANOVA was used. In the intervention group, the indexes showed significant improvements (P<0.001). This means that our intervention treatment was effective.<br> <strong>Conclusion:</strong> The study results support the effectiveness of the combination therapy (soft tissue release, muscle energy techniques plus exercise therapy) with some improvements in the neck ROM, NDI and pain (Based on VAS scores) for the management of patients with non-specific CNP.</p> <p></p><p></p><p></p><p></p> Chronic neck pain, Manual therapy, Exercise therapy, Soft tissue release, Muscle energy techniques, Physiotherapy 113 121 http://ptj.uswr.ac.ir/browse.php?a_code=A-10-42-15&slc_lang=en&sid=1 Maryam Ghodrati مریم قدرتی No Department of Physiotherapy, University of Social Welfare and Rehabilitation Sciences, Tehran, Iran.
