Cerebral infarction with no strength in hands and feet can be recovered with active treatment and rehabilitation exercise. Limb weakness is a common clinical symptom of cerebral infarction, and the brain is the central organ that governs limb movement. Therefore, if the brain is damaged due to ischemia after cerebral infarction, the activities of the dominant limbs will definitely be affected, that is to say, hemiplegia or single limb paralysis occurs after cerebral infarction, and even paralysis of all four limbs in serious cases. When limb paralysis occurs, if it is in the acute stage, it is necessary to seek medical treatment as early as possible to remove the cause of the disease within the time window. For example, in cerebral infarction, thrombolytic therapy to dissolve the thrombus and restore blood perfusion usually has a better effect and can restore the limb weakness, or even restore it completely. If the time window is exceeded, early medical attention should also be sought. Through the guidance of rehabilitation specialists and rehabilitation training, limb movement can be preserved as much as possible while recovering to some extent.
