the aggravation of social aging and the increase of the incidence rate of cerebral apoplexy make the cerebral apoplexy become the leading cause of the limb disability of the old. The central nervous system is damaged, and the stroke patient is accompanied with sequelae such as hemiplegia and motor function loss after an acute period, so that the patient is subjected to heavy burden on individuals, families and society. Clinical practice of rehabilitation medicine shows that due to the existence of neural plasticity, limb function rehabilitation is carried out as early as possible after the state of an illness is stable, and related neural circuits can be promoted to be reconstructed through repeated training, so that the motor function rehabilitation degree of a patient is obviously improved. Therefore, rehabilitation becomes an important link in the treatment process of stroke patients.
