Exercise therapy is widely used in the rehabilitation of stroke patients. Yoga exercise therapy is the typical one, but its specific effect and mechanism of action have not yet been clearly explained. In this context, 58 cases of stroke patients were randomly divided into experimental group and control group. Then, the effect of yoga exercise on the recovery of cognitive ability and motor function of stroke patients was explored by means of clinical controlled experiments. Through the monitoring and comparison of cerebral blood oxygen content, brain feedback-related negativity (FRN) and modified Barthel index (MBI) between the two groups of patients, it was found that yoga exercise therapy actually has a significant effect on improving the cognitive ability and motor function of stroke patients. Besides, from the point of view of the specific mechanism, yoga increases the patient’s nerve excitability by increasing blood oxygen content in the brain, while the increase in nerve excitability further enhances the patient’s ability to reflect, think, and control the body, so as to ultimately improve their cognitive ability and motor function
