Focused Shockwave Therapy for Neck and Shoulder Myofascial Pain

研究简介（原文）

Myofascial pain syndrome of the neck and shoulder is a common condition characterized by persistent muscle pain, tenderness, stiffness, and limitations in daily activities. Focused extracorporeal shockwave therapy is a noninvasive treatment that may reduce pain and improve muscle function. However, additional clinical evidence is needed regarding the effectiveness of second-generation focused shockwave therapy and whether ultrasound imaging can objectively detect changes in muscle function after treatment. This pilot randomized controlled trial will enroll 60 adults with chronic neck and shoulder myofascial pain syndrome. Participants will be randomly assigned to either a focused shockwave therapy group or a home-based neck exercise group. Participants in the focused shockwave therapy group will receive one treatment session per week for three consecutive weeks. Participants in the control group will perform a standardized home exercise program designed to improve neck mobility and reduce muscle tightness. Assessments will be performed before the intervention, after the intervention, and at follow-up. Study outcomes will include pain intensity measured using the Visual Analogue Scale, neck-related disability measured using the Neck Disability Index, pressure pain threshold measured using an algometer, and upper trapezius muscle thickness and contraction-related changes measured using ultrasound imaging. The primary objective is to determine whether focused shockwave therapy is more effective than a home-based neck exercise program in reducing pain and improving neck function. The study will also evaluate whether ultrasound-derived muscle measurements are associated with changes in pain, pressure sensitivity, and functional disability.
