Stroke survivors often present with abnormal gait, movement training can improve the walking performance post-stroke, and functional MRI can objectively evaluate the brain functions before and after movement training. This paper analyzes the functional MRI changes in patients with ischemic stroke after treadmill training with voluntary and passive ankle dorsiflexion. Functional MRI showed that there are some changes in some regions of patients with ischemic stroke including primary sensorimotor cortex, supplementary motor area and cingulate motor area after treadmill training. These findings suggest that treadmill training likely improves ischemic stroke patients' lower limb functions and gait performance and promotes stroke recovery by changing patients' brain plasticity; meanwhile, the novel treadmill training methods can better training effects.
脑卒中幸存者常表现出异常步态，运动训练可改善脑卒中后患者的步行能力，功能磁共振成像（fMRI）可客观评估运动训练前后的脑功能变化。本文分析了带主动和被动踝关节背屈的跑步机训练对缺血性脑卒中患者的 fMRI 变化。功能磁共振成像显示，跑步机训练后，部分缺血性脑卒中患者的初级感觉运动皮层、辅助运动区和扣带回运动区等区域发生了变化。这些发现提示跑步机训练可能通过改变患者的脑可塑性，从而提高下肢功能和步态表现，促进脑卒中康复；同时，新型跑步机训练方法可获得更好的训练效果。
