虚拟现实机器手对脑卒中患者手运动功能及日常生活活动的效果

Effect of Virtual Reality Robotic Hand on Hand Motor Function and Activities of Daily Living of Patients after Stroke

目的探讨虚拟现实机器手对脑卒中患者手运动功能障碍的疗效,以及对日常生活活动能力的影响。方法 2015年6月至2016年6月,32例脑卒中手运动功能障碍患者分为实验组(n=16)和对照组(n=16)。实验组予虚拟现实机器手训练和手部基础康复训练,对照组予手部基础康复训练,共4周。治疗前后采用Fugl-Meyer评定(FMA)的手指、腕运动部分和改良Barthel指数(MBI)进行评定。结果实验组治疗后FMA、MBI总分及各亚项评分明显提高(Z>3.45,t>3.45,P<0.01)。对照组治疗后FMA总分、手指、腕,MBI进食、穿衣、修饰共6项评分高于治疗前(Z>2.07,t>4.18,P<0.05)。治疗后,实验组FMA、MBI总分及各亚项评分高于对照组(Z>2.14,t>3.20,P<0.05)。结论虚拟现实机器手训练可进一步改善脑卒中患者的手功能和日常生活活动能力。

Objective To observe the effect of virtual reality robotic hand on hand motor function and activities of daily living of patients after stroke. Methods From June,2015 to June,2016,32 patients with hand motor dysfunction were assigned into experimental group（n=16） and control group（n=16）. The experimental group received training with virtual reality robotic hand and hand based rehabilitation,while the control group received hand based rehabilitation only,for four weeks. They were evaluated with Fugl-Meyer Assessment（FMA）of fingers and wrists and modified Barthel index（MBI） before and after treatment. Results The total score and the scores of items of FMA and MBI improved after treatment in the experimental group（Z〉3.45 or t3.45,P〈0.01）. The total score and the scores of the finger,wrist of FMA,and the scores of the eating,dressing and grooming of MBI improved in the control group（Z〉2.07 or t4.18,P〈0.05）. The total scores and scores of the items of FMA and MBI improved more in the experimental group than in the control group（Z〉2.14 or t〉3.20,P〈0.05）. Conclusion Virtual reality robotic hand training can promote the recovery of hand function and activities of daily living in patients after stroke.
