Ultrasound-Guided Myofascial Hydrodissection for Myofascial Pain Syndrome: A Retrospective Study on Pain Relief and Functional Improvement

Abstract Purpose This study aimed to evaluate the feasibility and safety of treating myofascial pain syndrome (MPS) with the ultrasound-guided myofascial hydrodissection technique (UMHT) to assess the efficacy of UMHT in alleviating pain and improving functional capacity among patients with MPS, contributing to the ongoing discourse regarding optimal treatment options for this condition. Methods This retrospective cohort study was conducted at a clinical research institution affiliated with a university. This study enrolled 28 individuals diagnosed with MPS, who received one session of UMHT weekly. Pain severity and functional parameters were assessed at baseline, 24 h, 2 weeks, 1 month, and 3 months post-treatment using the Visual Analogue Scale (VAS), McGill Pain Questionnaire, and Oswestry Disability Index (ODI), respectively. Results We observed a significant reduction in pain, as evidenced by improvements in VAS (χ² = 60.63, p < 0.01) and McGill scores (χ² = 57.31, p < 0.01). Additionally, we observed functional improvement, with a significant reduction in ODI scores (χ² = 55.66, p < 0.0001). No adverse events were reported throughout the study. Conclusion UMHT significantly reduced pain and improved functional capacity in patients with MPS. These findings suggest that UMHT is a promising and safe treatment for MPS, although further research is needed to confirm its long-term efficacy.
