目的 观察基于运动想象的手部机器人辅助训练对脑卒中患者手功能及上肢运动功能的影响。
方法 2016 年11 月至2018 年5 月,脑卒中后手功能障碍患者55 例,随机分为对照组(n = 25)和观察组(n = 30),对照组采用常规手功能活动,观察组采用手部机器人辅助训练,共4 周。于治疗前(t0)、治疗1 周(t1)、治疗后即刻(t2)、治疗后2 个月(t3)采用简式Fugl-Meyer 评定量表上肢部分(FMA-UE)、Wolf 上肢运动功能评价量表(WMFT)和改良Barthel 指数(MBI)进行评定。
结果 t1 时,观察组WMFT 评分较t0 改善(P < 0.05),两组间无显著性差异(Z = -0.901, P > 0.05)。t2、t3 时,两组FMA-UE 评分、MBI 评分和WMFT 评分均较t0 时改善(P < 0.05),观察组FMA-UE 评分和MBI 评分优于对照组(Z > -2.073, t > 2.034, P < 0.05)。
结论 基于运动想象的手部机器人辅助训练比常规手训练更有效。
Objective To investigate the effect of hand robot-assisted training based on motor imagery on upper limb function of stroke patients.
Methods From November, 2016 to May, 2018, 55 hemiplegic patients with upper limb dysfunction were randomly assigned to control group (n = 25) and experimental group (n = 30). The control group received routine hand motor training, while the experimental group received hand robot-assisted training, for four weeks. They were assessed with simplified Fugl-Meyer Assessment-Upper Extremity (FMA-UE), Wolf Motor Function Test (WMFT) and Modified Barthel Index (MBI) before treatment (t0), one week of treatment (t1), immediately after treatment (t2) and 2 months after treatment (t3).
Results The score of WMFT improved in the experimental group at t1 (P < 0.05), with no significant difference be-tween groups (Z = -0.901, P > 0.05). The scores of FMA, WMFT and MBI improved in both groups at t2 and t3 (P < 0.05), and the scores of FMA and MBI improved more in the experimental group than in the control group (Z > -2.073, t > 2.034, P < 0.05).
Conclusion Hand robot-assisted training based on motor imagery can promote recovery of upper limb function in stroke patients more effective than routine hand function training.
