Abstract

Objective: To assess the effects of mobilization with movement (MWM) on pain, range of motion (ROM), and disability in the management of shoulder musculoskeletal disorders.

Methods: Six databases and Scopus, were searched for randomized control trials. The ROB 2.0 tool was used to determine risk-of-bias and GRADE used for quality of evidence. Meta-analyses were performed for the sub-category of frozen shoulder and shoulder pain with movement dysfunction to evaluate the effect of MWM in isolation or in addition to exercise therapy and/or electrotherapy when compared with other conservative interventions.

Results: Out of 25 studies, 21 were included in eight separate meta-analyses for pain, ROM, and disability in the two sub-categories. For frozen shoulder, the addition of MWM significantly improved pain (SMD -1.23, 95% CI -1.96, -0.51)), flexion ROM (MD -11.73, 95% CI -17.83, -5.64), abduction ROM (mean difference -13.14, 95% CI -19.42, -6.87), and disability (SMD -1.50, 95% CI (-2.30, -0.7). For shoulder pain with movement dysfunction, the addition of MWM significantly improved pain (SMD -1.07, 95% CI -1.87, -0.26), flexion ROM (mean difference -18.48, 95% CI- 32.43, -4.54), abduction ROM (MD -32.46, 95% CI - 69.76, 4.84), and disability (SMD -0.88, 95% CI -2.18, 0.43). The majority of studies were found to have a high risk of bias.

Discussion: MWM is associated with improved pain, mobility, and function in patients with a range of shoulder musculoskeletal disorders and the effects clinically meaningful. However, these findings need to be interpreted with caution due to the high levels of heterogeneity and risk of bias.

Level of evidence: Treatment, level 1a.
