: To determine the effect of mirror visual feedback (MVF) on disability, pain, and motor function on patients who underwent hand reconstructive surgery.
: Randomized, single-blinded controlled trial.
: Rehabilitation center.
: A total of 40 patients who were randomly assigned into the intervention group ( n = 20) and control group ( n = 20) participated in this study.
: The rehabilitation sessions took place twice a week for eight weeks. The control group received traditional rehabilitation for 75 minutes. While the intervention group performed MVF and traditional rehabilitation for 30 and 45 minutes, respectively.
: Pain and disability of the hand were assessed with McGill pain questionnaire and Disability of Arm, Shoulder, and Hand (DASH) scores. The range of joint motion was evaluated by Goniometer, and the strength of grip and pinch was evaluated by Dynamometer and Pinch gauge and dexterity evaluated by Minnesota Manual Muscle test.
: The results indicated that both traditional and MVF methods induced significant decreasing pain (Pain Rate Index: F = 68.48, P = 0.000; Number of Word Count: F = 70.96, P = 0.000), disability ( F = 50.08, P = 0.000) and increasing dexterity (placing test: F = 28.73, P = 0.000), and range of motion ( F = 33.16, P = 0.000). The results also showed that the positive effect of MVF on pain, disability, dexterity, and range of motion was significantly greater than that of controls ( P < 0.05), but there was no significant result in grip and lateral pinch strength between the intervention and control group ( P > 0.05).
: MVF, in conjunction with traditional rehabilitation programs, may lead to greater improvements in pain, disability, placing dexterity, and range of motion. But it seems not to be effective on pinch and grip power and turning dexterity.
探究镜像视觉反馈（MVF）对手部重建手术后患者的残疾、疼痛和运动功能的影响。
随机、单盲对照试验。
康复中心。
共 40 名患者被随机分配到干预组（n=20）和对照组（n=20），参与了这项研究。
康复治疗每周进行两次，共进行 8 周。对照组接受传统康复治疗 75 分钟，而干预组则分别接受 30 分钟和 45 分钟的 MVF 和传统康复治疗。
手部疼痛和残疾程度采用 McGill 疼痛问卷和手臂、肩部和手部残疾（DASH）评分进行评估。关节活动范围通过量角器进行评估，握力和捏力通过测力计和捏力计进行评估，灵巧性通过明尼苏达州手动肌肉测试进行评估。
结果表明，传统和 MVF 方法均能显著降低疼痛（疼痛率指数：F=68.48，P=0.000；字数计数：F=70.96，P=0.000）、残疾（F=50.08，P=0.000）和提高灵巧性（放置测试：F=28.73，P=0.000），以及活动范围（F=33.16，P=0.000）。结果还表明，MVF 对疼痛、残疾、灵巧性和活动范围的积极影响明显大于对照组（P<0.05），但干预组和对照组之间的握力和侧捏力无显著差异（P>0.05）。
MVF 与传统康复方案结合使用，可能会带来更大的疼痛、残疾、放置灵巧性和活动范围的改善。但它似乎对捏力和握力以及转动灵巧性没有效果。
