PURPOSE: The main purpose of this meta-analysis study was to identify the degree-of-effect size and the variables for the effects of manual physical therapy on myofascial pain syndrome.
METHODS: This study collected six studies published between 2015.01.01 and 2019.12.31. The analysis result verified nine effect size data. The random-effect model was chosen because of the heterogeneity of the data. RESULTS: First, the full case showed the largest mean effect size of 2.297 (p < .001). Second, the size of the effect based on the fascial distortion model (FDM) intervention showed an effect size of 4.654 (p < .001). Third, the number of participants showed a 15 or less effect size of 2.612 (p > .058). The number of treatments showed a 10 less effect size of 2.844 (p > .129). The publication type showed a thesis effect size of 3.095 (p < .002).
CCONCLUSION: Manual physical therapy has a great effect on myofascial pain syndrome in the neck and shoulders, and that the effects differ according to the methods of intervention.
