Abstract

Abstract:

Objective To explore the rehabilitation effects of a mirror-imaging rehabilitation robot on hand motor function in subacute stroke patients. Methods This retrospective study enrolled subacute stroke patients from June to August 2020. They were randomly divided into observation group and control group by envelope method. Conventional rehabilitation therapy was given in both groups, rehabilitation robot was added on this base in observation group, which lasted for 4 weeks. Hand function was evaluated before and after 4 weeks treatment, and the evaluation tools included Fugl-Meyer assessment upper extremity (FMA-UE), FMA-UE hand score, box and block test (BBT), action research arm test (ARAT), and modified Barthel index (MBI), grip strength and pinch strength of the affected hand. Results A total of 40 patients were included, with 20 ones in each group. There was no statistical difference in each index between the two groups before and after treatment. For intra-group comparison, only MBI (P =0.049) in control group was higher after treatment than before treatment, while FMA-UE score (P =0.024) and FMA-UE hand score (P =0.046) in observation group were higher after treatment than before treatment. For improvement degree, the improvement score of FMA-UE score (P =0.038) and FMA-UE hand score (P =0.048) in observation group were all higher than that in control group. Conclusions The mirror-imaging rehabilitation robot can improve hand motor function in subacute stroke patients, which can be used as an auxiliary therapy technology.

摘要：

目的探讨镜像运动模式康复机器人对卒中亚急性期手运动功能障碍患者的康复效果。方法选取2020年6-8月于上海第三康复医院连续收治的卒中亚急性期患者为研究对象，采用信封法将患者随机分为观察组和对照组，两组均予常规康复治疗，观察组在此基础上予康复机器人手套治疗，共治疗4周。在两组治疗前后分别进行手功能评估，包括Fugl-Meyer上肢运动功能评定（Fugl- Meyer assessment upper extremity，FMA-UE）、FMA-UE手部评分、箱盒测试（box and block test，BBT）、上肢动作研究测试（action research arm test，ARAT）、改良Barthel指数（modified Barthel index，MBI），以及患侧手握力和捏力。结果本研究最终纳入40例患者，两组各20例。治疗前和治疗后两组间各项指标评估结果比较，差异均无统计学意义。治疗后组内比较结果显示，对照组MB（I P=0.049）高于治疗前，观察组FMA-UE评分（P =0.024）与FMA-UE手部评分（P =0.046）高于治疗前。两组各指标进步程度比较结果显示，观察组FMA-UE评分（P =0.038）与FMA-UE手部评分（P =0.048）差值均高于对照组。结论镜像康复机器人对卒中亚急性期患者的手运动功能改善具有促进作用，可以作为一种辅助治疗技术应用于临床。
