The golden rehabilitation time for cerebral infarction is within 3-6 months after the acute phase of cerebral infarction, and in this period of time, under the guidance of the rehabilitation teacher, patients can carry out effective rehabilitation training, and almost all patients with limb function at muscle strength four and above can recover to normal without leaving obvious sequelae of neurological function. However, even patients with limb muscle strength of three and below should insist on rehabilitation training, because active rehabilitation helps to gradually recover limb muscle strength, and continuous rehabilitation exercises are necessary even if they leave hemiplegic sequelae, and they should not be discouraged even if they are more than 6 months old. Therefore, it is recommended that patients with cerebral infarction must start rehabilitation training as early as possible and seize the golden period of 3-6 months, and those who subsequently remain with sequelae should not be discouraged to persist in rehabilitation training.
