Background

Repetitive transcranial magnetic stimulation (rTMS) has shown potential in alleviating hemiplegic shoulder pain (HSP) and improving upper limb function, yet its efficacy remains debated. This study aims to assess the effectiveness of rTMS for HSP through a systematic review and meta-analysis.

Methods

Four databases were searched with the keywords “rTMS” and “HSP”. Adults aged 18 years and older with post-stroke HSP were included. The primary outcomes were pain scores and upper limb function scores, and the secondary outcomewas the incidence of adverse events. The risk of bias was assessed through the ROB tool in Review Manager 5.4.1, and statistical analysis was primarily conducted through this software.

Results

A total of 52 articles were identified from PubMed, Embase, Cochrane Library, and CNKI. Following literature screening, 11 studies were included in the analysis. The quality of the included studies was moderate.The studies encompassed 584 patients with post-stroke HSP and their average age was 62. The analysis revealed that rTMSwas significantly more effective in relieving pain compared to the control group (SMD = -1.14, p < 0.01), and low-frequency rTMSwas superior to high-frequency rTMS. In terms of improving upper limb function, rTMSwas also significantly more efficacious compared to the control group (SMD = 2.20, p < 0.01), and low-frequency and high-intensity rTMSwere more beneficial.

Conclusions

This study highlights the potential efficacy of rTMS. However, the heterogeneity among included studies, limited sample sizes, and lack of long-term follow-up data restrict the generalizability of the results.
