This systematic review, titled "Revitalizing Relief: A Systematic Review of Extracorporeal Shockwave Therapy for Myofascial Pain Syndrome in the Upper Trapezius," critically evaluates the efficacy of extracorporeal shockwave therapy (ESWT) as a treatment modality for myofascial pain syndrome (MPS) specifically targeting the upper trapezius muscle. The review synthesizes evidence from relevant studies to provide a comprehensive overview of the therapeutic benefits, limitations, and potential implications of ESWT in managing MPS in this specific anatomical region. Through a rigorous analysis of existing literature, this review aims to inform clinicians, researchers, and healthcare practitioners about the current state of knowledge regarding the application of shockwave therapy for myofascial pain in the upper trapezius.
