Additional Effect of Extracorporeal Shockwave Therapy with Lidocaine Injection on Clinical and MRI Findings in Frozen Shoulder: A Prospective, Randomized, Double-Blinded, Placebo-Controlled Trial.

研究概要

Sixty patients with frozen shoulder were randomized to receive either lidocaine injection with active extracorporeal shockwave therapy (ESWT; n=30) or lidocaine injection with placebo ESWT (n=30). Outcomes of interest were pain intensity measured by the visual analog scale (VAS), the thickness of the coracohumeral ligament (CHL) assessed by MRI, abduction and lateral rotation range of motion (ROM), functional disability, kinesiophobia, depression status, and quality of life. Outcomes were assessed at baseline, after 4 weeks, 8 weeks, and at 6-month follow-up. Overall, the results of the study revealed significant improvements in the active ESWT group compared to the placebo group across outcomes. The study concluded that ESWT in addition to lidocaine injection significantly enhances pain relief, ROM, functional ability, and quality of life in frozen shoulder patients.
