efficacy of extracorporeal shock wave therapy on active trigger point in the upper trapezius muscle

Introduction: to demonstrate the effectiveness of extracorporeal shock wave therapy(eswt) in treating active trigger points to relieve pain and increase range of motion(rom) and improve the function of the cervical region in fewer sessions.materials and methods: in this single-group, pretest-posttest study, 15 participants withactive myofascial trigger points (mtrps) in the upper trapezius muscle took part. beforeand after each treatment, visual analog scale (vas), pressure pain threshold (ppt), neckdisability index (ndi) questionnaire, and range of active contra lateral flexion (clf)were assessed. participants were given three treatments over a week, with at least a twodaybreak between them, and then all outcomes were evaluated.results: the general results of this study demonstrate a significant reduction in painperception in terms of vas (p=0.0001), increased pressure pain threshold (p=0.0001),increased clf of rom (p=0.0001), and improved neck function by reduction of ndi(p=0.0001), after the third session of eswt intervention in participants with mtrp inthe upper trapezius muscle.conclusion: it reveals that eswt has positive effects on pain reduction, cervical range ofmotion, and cervical function in participants treated with mtrps in the upper trapezius muscle.
