Effect of Mobilization with Movement on Pain, Disability, and Range of Motion in Patients with Shoulder Pain and Movement Impairment: A Systematic Review and Meta-Analysis

Abstract

Background: Shoulder pain is a disabling musculoskeletal disorder worldwide. Thus, it is important to identify interventions able to improve pain and disability. Objective: To investigate the effects of mobilization with movement (MWM) on pain, disability, and range of motion in patients with shoulder pain and movement impairment. Methods: A systematic search of different databases was performed. The systematic review protocol has been registered in PROSPERO (CRD42023404128). A random-effects model for meta-analysis was used to determine the mean difference (MD), standardized mean differences (SMD), and 95% confidence interval for the outcome of interest. Results: Twenty-six studies were included. Of these, eighteen were included in the meta-analysis. MWM improved pain during movement with a moderate effect SMD of (−0.6; 95% confidence interval, −1.1 to −0.1, I2 = 0%; N = 66;) and shoulder abduction MD of (12.7°; 1.3 to 24.0; I2 = 73%; N = 90) compared to sham MWM in the short term (0–6 weeks). Combined MWM and conventional rehabilitation improved pain at rest, with a MD of (−1.2; −2.2 to −0.2; I2 = 61%; N = 100), and disability SMD of (−1.3; confidence interval −2.2 to −0.4; I2 = 87%; N = 185) compared to conventional rehabilitation alone in the short term. Combined MWM and conventional rehabilitation also resulted in improvement in shoulder abduction and external rotation. Compared to Maitland, MWM resulted in improvement in the shoulder abduction MD (20.4°; confidence interval 4.3 to 36.5; I2 = 89%; N = 130) in the short term. There is no information regarding long-term effects. Conclusion: Evidence suggests that MWM may reduce shoulder pain and restore shoulder range of motion and function. Our findings are promising, but the evidence is not strong enough to recommend it pragmatically.
