The characteristic of motor paralysis in this disease is hemiplegia opposite the damaged brain area, including the arms (upper limbs), legs (lower limbs) and trunk muscles. In the acute phase, patients often have flaccid paralysis (ie decreased muscle tone). After moving to the recovery phase, flaccid paralysis will turn into spastic paralysis. Patients will have gradually increased muscle tone, which can lead to a spastic pattern - stiff flexion of the upper limbs, stiff extension of the lower limbs, causing pain and making movement more difficult.
