设计图：单个病例。目的：比较截瘫患者手动辅助运动训练与驱动步态矫形器自动训练的效果，设置：ParaCare，瑞士苏黎世巴尔格瑞斯特大学医院。对两名脊髓损伤患者进行了手动辅助和驱动步态矫形器的跑步机训练，第一名患者在C3处有不完全损伤，第二名患者在C5处有完全损伤，他们是通过方便抽样选出的。小腿肌肉的肌电活动股直肌、股二头肌。腓肠肌内侧（GM）和胫骨前肌（TA）的视觉比较两种训练方法。GM和TA活性也通过计算患者和一组健康受试者的EMG之间的变化率来量化。结果：根据腿部肌肉EMG活性，两种训练方法之间没有发现显著差异。脊髓中的神经元中心通过手动辅助和自动运动训练以类似的方式被激活，利用驱动步态矫形器，可以延长训练课程，并且可以减少治疗师的工作量，因此，自动化训练代表了传统治疗的替代方案。
Design: Single cases.Objective: To compare the effects of manually assisted locomotor training in paraplegic patients with the automated training by a driven gait orthosis,Setting: ParaCare, University Hospital Balgrist in Zurich, Switzerland.Methods: Treadmill training with manual assistance and by a driven gait orthosis was applied to two spinal cord injured patients, The first patient had an incomplete lesion at C3, the second a complete lesion at C5, They were selected by convenience sample. The EMG activity of the leg muscles rectus femoris, biceps femoris. gastrocnemius medials (GM) and tibialis anterior (TA) was visually compared for the two training methods. GM and TA activity was also quantified by calculating the variation ratio between the EMG of the patients and a set of healthy subjects.Results: No significant difference between the two training methods was found according to the leg muscle EMG activity.Conclusion: Neuronal centers in the spinal cord become activated in a similar way by the manually assisted and the automated locomotor training, With the driven gait orthosis training sessions can be prolonged and workload of therapists can be reduced, and therefore, the automated training represents an alternative to the conventional therapy.
