目的探讨虚拟现实(VR)技术结合运动想象疗法对脑卒中患者上肢功能恢复的影响。方法选取39例脑卒中偏瘫患者,按随机数字表法将其分成治疗组(20例)和对照组(19例),对照组给予运动想象疗法,治疗组在此基础上辅以VR技术,每次30min,每周6次,共8周。治疗前、后对2组患者进行评定,采用上肢Fugl—Meyer评分(FMA)评定患者的上肢运动功能,采用改良Barthel指数(MBI)评定患者的日常生活活动能力,并采用肌电图仪测定患者偏瘫侧上肢相关肌肉的肌电积分(iEMG)。结果治疗前,2组患者上肢FMA评分、MBI评分及患侧上肢肌肉iEMG值组间比较,差异均无统计学意义(P〉0.05);治疗8周后,2组患者上述指标均较治疗前显著改善(P〈0.05),且治疗组FMA评分(32.7±5.5)分、MBI评分(59.6±10.1)分、三角肌iEMG值(52.4±11.6)μV、肱三头肌iEMG值(38.6±7.3)μV、前臂伸肌肌群iEMG值(29.4±5.7)仙V的改善幅度均较对照组显著(P〈0.05)。结论VR技术结合运动想象疗法可更有效改善脑卒中偏瘫患者的上肢运动功能及日常生活活动能力。
Objective To explore the effects of virtual reality (VR) combined with motor imagery therapy on the upper limb function of hemiplegie stroke survivors. Methods Thirty-nine hemiplegic stroke patients were di- vided randomly into a treatment group ( n = 20) and a control group ( n = 19). Both groups were treated with motor imagery therapy, but the treatment group also received VR training lasting 20 min/day, 6 days/week for 8 weeks. All of the patients were assessed with the Fugl-Meyer (FMA) upper limb assessment, the modified Barthel index (MBI) and electromyography at the beginning and after eight weeks of treatment. Results Before the intervention there was no significant difference between the groups in any of the assessments. After eight weeks of treatment, all the as- sessment results in the treatment group were significantly better than those in the control group. Conclusion Virtu- al reality combined with motor imagery therapy can distinctly improve the upper limb motor function of hemiplegic stroke survivors and their ability in the activities of daily living.
