OBJECTIVE To determine the effectiveness of mental simulation practice (MSP) on measures of physical function recovery in patients who have undergone a joint replacement surgery of lower limbs. DATA SOURCES A systematic review was conducted using CINAHL, PubMed/MEDLINE, Embase, SPORT Discus, PEDro, Cochrane Register of Controlled Trials and Google Scholar from earliest record to 16th August 2019. STUDY SELECTIONS The following inclusion criteria were used to determine eligibility for studies: 1) randomised and matched controlled trials recruiting male and female adults who underwent primary unilateral joint arthroplasty; 2) the study examined effects of MSP intervention on measures of physical function recovery (both performance-based and patient self-reported); 3) measures of interest were compared between MSP and control groups. A total of eight papers (seven studies) met the inclusion criteria and were included. DATA EXTRACTION Data were extracted by one reviewer and checked by a second reviewer, independently. DATA SYNTHESIS When compared to standard physical therapy (SPT), MSP showed an effect on physical function in general (effect size (ES) = 0.67, 95% CI 0.38 to 0.96, n = 7), maximal voluntary strength of knee extensor muscles of the affected leg (ES = 1.41, 95% CI 0.64 to 2.18, n = 2), brisk walking speed (ES = 1.20, 95% CI 0.58 to 1.83, n = 2), brisk walking speed with dual task (ES = 1.02, 95% CI 0.41 to 1.63, n = 2), timed up-to go test (ES = 0.96, 95% CI 0.15 to 1.77, n = 3) and active flexion of the affected leg (ES = 0.70, 95% CI 0.29 to 1.11, n = 4). Finally, meta-regression analysis revealed that effects of MSP were significantly predicted only by total number of training sessions per study. CONCLUSIONS The present meta-analysis demonstrated that MSP intervention has multiple positive effects on measures of physical function recovery in patients who have undergone total knee or hip replacement surgery in comparison with SPT. Thus, MSP can be applied as an effective complementary therapy to SPT in physical rehabilitation of this specific population, especially in the early post-acute and acute phase.

心理模拟练习对下肢关节置换术后患者身体机能的有益影响：系统评价和荟萃分析

目的 确定心理模拟练习（MSP）对下肢关节置换手术患者身体功能恢复测量的有效性。数据来源 从最早记录到 2019 年 8 月 16 日，使用 CINAHL、PubMed/MEDLINE、Embase、SPORT Discus、PEDro、Cochrane Register of Controlals 和 Google Scholar 进行了系统评价。 研究选择 以下纳入标准用于确定研究的资格: 1) 随机匹配对照试验，招募接受单侧关节置换术的男性和女性成年人；2) 该研究检查了 MSP 干预对身体功能恢复措施的影响（基于表现和患者自我报告）；3) 在 MSP 和对照组之间比较感兴趣的测量。共有八篇论文（七项研究）符合纳入标准并被纳入。数据提取 数据由一位评论员提取并由另一位评论员独立检查。数据综合 与标准物理治疗 (SPT) 相比，MSP 显示出总体上对身体功能的影响（效果大小 (ES) = 0.67，95% CI 0.38 至 0.96，n = 7），膝伸肌的最大自主力量为受影响的腿（ES = 1.41，95% CI 0.64 至 2.18，n = 2），快走速度（ES = 1.20，95% CI 0.58 至 1.83，n = 2），双任务快走速度（ES = 1.02） , 95% CI 0.41 至 1.63, n = 2), 计时测试 (ES = 0.96, 95% CI 0.15 至 1.77, n = 3) 和受影响腿的主动屈曲 (ES = 0.70, 95% CI 0.29 到 1.11，n = 4）。最后，元回归分析显示 MSP 的影响仅通过每项研究的培训课程总数进行显着预测。结论 本荟萃分析表明，与 SPT 相比，MSP 干预对接受全膝关节或髋关节置换手术的患者的身体功能恢复措施具有多种积极影响。因此，MSP 可以作为 SPT 的有效补充疗法应用于该特定人群的身体康复，尤其是在急性后期和急性期。
