To evaluate the effectiveness of mirror therapy (MT) for phantom limb pain (PLP).
PubMed, EMBASE, Ovid MEDLINE, Scopus, Cochrane Library, Physiotherapy Evidence Database, CNKI, and WanFang Data were used to search for studies published up to March 31, 2021.
Randomized controlled trials (RCTs) comparing the pain intensity of MT for PLP were performed. A total of 2094 articles were found. Among them, 10 were eligible for the final analysis.
The quality of the RCTs was assessed using the Physiotherapy Evidence Database (PEDro) scale by 2 independent reviewers. Outcome data were pooled according to follow-up intervals (1, 3, 6, and 12mo). Duration times were used as a basis for distinguishing subgroups. The primary evaluation was by visual analog scale. The PEDro scale was used to assess the methodological quality of studies.
Meta-analysis revealed a statistically significant decrease in pain in the MT group vs the control group within 1 month (I=0%; standardized mean difference [SMD]=-0.46, 95% confidence interval [CI], -0.79 to -0.13; P = .007). The patients with pain for longer than 1 year benefited more from MT (I=0%; SMD=-0.46; 95% CI, -0.85 to -0.07; P = .02).
MT has beneficial effects for patients with PLP in the short-term, as evidenced by their improved pain scores. There was no evidence that MT had a long-term effect, but that may be a product of limited data. For patients with long-term PLP, MT may be an effective treatment.
评估镜像疗法（MT）对幻肢痛（PLP）的疗效。
使用PubMed、EMBASE、Ovid MEDLINE、Scopus、Cochrane图书馆、物理治疗证据数据库、中国知网和万方数据检索截至2021年3月31日发表的研究。
进行了比较MT治疗PLP疼痛强度的随机对照试验（RCT）。共找到2094篇文章。其中，10篇符合最终分析的条件。
由2名独立评审员使用物理治疗证据数据库（PEDro）量表评估RCT的质量。根据随访间隔（1、3、6和12个月）汇总结果数据。持续时间用作区分亚组的依据。主要评估采用视觉模拟量表。PEDro量表用于评估研究的方法学质量。
荟萃分析显示，与对照组相比，MT组在1个月内疼痛有统计学显著降低（I=0%；标准化平均差[SMD]=-0.46，95%置信区间[CI]，-0.79至-0.13；P = 0.007）。疼痛超过1年的患者从MT中获益更多（I=0%；SMD=-0.46；95% CI，-0.85至-0.07；P = 0.02）。
MT对PLP患者在短期内有有益效果，疼痛评分改善证明了这一点。没有证据表明MT有长期效果，但这可能是数据有限的结果。对于长期PLP患者，MT可能是一种有效的治疗方法。
