Sequelae do not necessarily occur after a cerebral infarction. Whether there are sequelae after cerebral infarction is related to the degree of disease, timing of treatment, individual situation and other factors. 1. Degree of disease: If the lesion of a patient with cerebral infarction is superficial and does not involve important functional areas, there will not be any after-effects through active rehabilitation treatment. If the patient’s injury is deeper, the scope of injury is larger, and there is a combination of underlying diseases, generally there will be different degrees of sequelae. 2. Timing of treatment: the time point of rehabilitation after cerebral infarction can generally be carried out after the condition is stabilized, and early rehabilitation can be carried out. 3-6 months after the onset of the disease, the patient should actively carry out rehabilitation treatment, which can help the patient’s function to be restored earlier. If the patients do not get good rehabilitation treatment within 6 months, the rehabilitation effect will be reduced in the sequelae period of cerebral infarction. 3. Individual factors: mainly including the patient’s age, whether there is cognitive impairment, the patient’s emotional state and other factors also have a great relationship with the recovery time, these factors will lead to the patient’s training can not be cooperated with the training enthusiasm is not high, which will slow down the progress of the recovery, the sequelae of cerebral infarction. Patients with cerebral infarction should undergo early rehabilitation therapy and actively cooperate with doctors and therapists to promote early recovery of limb function.
