机器人辅助训练对上运动神经元损伤所致上肢痉挛的疗效观察

目的：为观察机器人辅助训练对上运动神经元损伤所致上肢痉挛的疗效并探讨其机制。方法：22例慢性脑卒中和脑外伤患者参加了这项研究，训练前4周，训练开始前1天和结束后1天使用改良Ashworth量表评价患侧上肢肘关节屈肌与伸肌的痉挛状态。训练时间为4周，每周训练5天，每次45min。结果：机器人辅助训练后，肘关节屈肌的痉挛评分降低，与基线相比有显著的差异性，而肘关节伸肌的痉挛评分有降低的趋势，但没有达到显著性水平。结论：机器人辅助训练对上运动神经元损伤所致上肢痉挛有一定的减轻作用，主要通过重复性牵伸和反复运动来实现。

An effect of spasticity due to upper motor neurone injury by robot-aided training

Objective: To investigate an effect of spasticity due to upper motor neurone injury by robot-aided training and explore its mechanism.Method:Twenty-two persons with chronic stroke and brain injury were enrolled in the research. Modified Ashworth scales(MAS) of elbow joints was carried out during 4 weeks before training, one day before training and one day after training. The patients were trained in the robot for 45 minutes, 5 times every week over 4 weeks. Result: MAS was significantly decreased in elbow flexor and not significant reduced compared with baseline assessment.Conclusion: Robot-aided training can reduce spasticity due to upper motor neurone injury mainly by repetitive stretching and movement.
