Efficacy of Combining Acupuncture and Physical Therapy for the Management of Patients With Frozen Shoulder: A Systematic Review and Meta-Analysis

Abstract

BackgroundFrozen shoulder, a debilitating condition causing pain and restricted joint mobility, often challenges conventional physical therapy methods. This study investigates the efficacy of combined acupuncture and physical therapy regimen, as opposed to physical therapy alone, for pain reduction and improvement of the clinical effective rate and the range of motion in patients with frozen shoulder. MethodsA systematic search of PubMed, Scopus, Cochrane Trial, and Web of Science databases was done for randomized controlled trials, quasi-experimental, and nonrandomized studies, reporting data of adult (>18 years) patients with frozen shoulder who received physical therapy with or without acupuncture. Outcomes of interest were pain, clinical effective rate, active and passive range of motion. Data were analyzed using STATA software, employing a random-effects model and standardized mean differences (SMD) and odds ratios (OR) for outcome measures. ResultsA total of 13 studies were included. The combined approach significantly reduced pain (SMD = –0.891) with considerable heterogeneity (I² = 85.3%) and improved clinical effective rates (OR = 3.693, I² = 0%). Significant improvements were also observed in active and passive range of motion, with varying degrees of heterogeneity. ConclusionThe combination of acupuncture and physical therapy is more effective than physical therapy alone in managing pain, improving clinical effective rates, and enhancing range of motion in patients with frozen shoulder. These findings suggest that incorporating acupuncture into standard rehabilitation protocols could enhance patient outcomes.
