Patients with cerebral infarction can’t swim in the acute stage, but if patients with cerebral infarction have been treated actively, they can have swimming exercise when there is no sequelae of neurological deficits. Cerebral infarction can be caused by atherosclerosis leading to cerebral vascular occlusion, or it can be caused by embolism. Patients with cerebral infarction have symptoms of neurological deficits in the acute stage, and swimming can induce vasospasm and lead to the aggravation of weakness of the affected limbs, so patients with cerebral infarction in the acute stage can’t swim. If patients with cerebral infarction have been actively treated without sequelae of neurological deficits, and at the same time, blood pressure, blood sugar, blood lipids and other cerebrovascular risk factors are relatively well controlled, the patients can carry out swimming exercise. Swimming belongs to aerobic exercise, which can exercise the cardiopulmonary function of patients with cerebral infarction, and at the same time, it can also fight against atherosclerosis, and it is also good for controlling cerebrovascular risk factors such as blood pressure and blood sugar.
