We performed a systematic review and meta-analysis to assess the efficacy of pulsed electromagnetic field (PEMF) therapy in treating patients with shoulder impingement syndrome. We sourced data from PubMed, the Cochrane Library, and Embase databases up until June 19, 2024. Our analysis included randomized controlled trials (RCTs) that evaluated the impact of PEMF therapy on pain levels and functional capacity in these patients. In total, four RCTs involving 252 participants were included. The pooled data indicated that PEMF therapy significantly reduced short-term pain (standardized mean difference [SMD] = -0.34, 95% confidence interval [CI] = -0.66 to -0.01, three RCTs, n = 166) and improved both short-term (SMD = 0.4, 95% CI = 0.08 to 0.73, three RCTs, n = 166) and long-term functional capacity (SMD = 0.6, 95% CI = 0.33 to 0.88, three RCTs, n = 212). The aforementioned results all achieved clinical significance. The observed low heterogeneity for short-term pain, along with short term and long-term functional capacity, highlights the sustained robustness and consistency of the effect on functional capacity over time. These results suggest that PEMF therapy is statistically effective in enhancing short-term pain relief and improving both short-term and long-term functional capacity in patients with shoulder impingement syndrome, with clinically significant benefits. However, the study limitations include a small sample size and variability in PEMF protocols, highlighting the necessity for standardized methodologies in future research.
我们进行了一项系统评价和荟萃分析，以评估脉冲电磁场（PEMF）疗法治疗肩峰撞击综合征患者的疗效。我们从PubMed、Cochrane图书馆和Embase数据库中获取截至2024年6月19日的数据。我们的分析纳入了评估PEMF疗法对这些患者疼痛水平和功能能力影响的随机对照试验（RCT）。总共纳入了四项涉及252名参与者的RCT。汇总数据表明，PEMF疗法显著减轻了短期疼痛（标准化均值差[SMD]= -0.34，95%置信区间[CI]= -0.66至-0.01，三项RCT，n = 166），并改善了短期（SMD = 0.4，95%CI = 0.08至0.73，三项RCT，n = 166）和长期功能能力（SMD = 0.6，95%CI = 0.33至0.88，三项RCT，n = 212）。上述结果均具有临床意义。观察到的短期疼痛以及短期和长期功能能力的低异质性，突出了随着时间推移对功能能力影响的持续稳健性和一致性。这些结果表明，PEMF疗法在增强肩峰撞击综合征患者的短期疼痛缓解以及改善短期和长期功能能力方面具有统计学效果，具有临床显著益处。然而，研究局限性包括样本量小和PEMF方案的变异性，这突出了未来研究中标准化方法的必要性。
