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.展开更多
