The purpose of this study is to explore the effect of rehabilitation training on limb recovery of patients with cerebral infarction hemiplegia and the improvement of daily life activities of patients. In this study, 46 patients with cerebral infarction hemiplegia are selected as the research subjects. All of them receive rehabilitation training within 0 to 24 h after the acute phase of cerebral infarction and the patient's vital signs are stable. After rehabilitation training for 2 w and 4 w, the motor function and daily life activity of hemiplegic limbs are evaluated, and the muscle strength recovery of patients is evaluated after rehabilitation training for 2 mo. The results show that after rehabilitation training, the muscle strength of hemiplegic patients with cerebral infarction is obviously restored, and the motor function of hemiplegic limbs and the ability of daily activities are significantly improved. Therefore, it can be concluded that rehabilitation training is conducive to promoting the recovery of limb motor function in patients with cerebral infarction hemiplegia and improving the life ability of patients, which has the promotion value. In the future research, large sample, multi-center randomized clinical control trial should be carried out to provide more reliable and effective rehabilitation mode for limb recovery of patients with cerebral infarction hemiplegia.
