Stroke (cerebral stroke) is also known as stroke. Is an acute cerebrovascular disease, which is a group of diseases causing brain tissue damage due to sudden rupture of cerebral vessels or failure of blood flow into the brain due to vessel occlusion, including ischemic and hemorrhagic stroke. The incidence rate of ischemic stroke is higher than hemorrhagic stroke, and accounts for 60-70% of the total stroke. The occlusion and stenosis of internal carotid and vertebral arteries can cause ischemic stroke, the age is more than 40 years old, more men than women, severe people can cause death, and the death rate of hemorrhagic stroke is higher. The stroke has a plurality of sequelae, the rehabilitation is difficult, and the optimal rehabilitation time is a period of time just after the stroke, so the limb function evaluation and the rehabilitation training are needed, the recovery can be better realized, and the influence degree of the sequelae is reduced.

The sequelae of stroke are characterized by:

1. hemorrhagic stroke sequelae include limb dysfunction mainly manifested by hemiplegic lateral sensation and motor dysfunction; cerebral hemorrhage with a greater range of cognitive and mental or multiple relapses, can be left with mental and cognitive disorders: such as personality change, negative pessimism, depression and depression of the body, listlessness, easy excitement, etc.; speech dysfunction; swallowing dysfunction; other symptoms such as headache, vertigo, nausea, insomnia, dreaminess, inattention, tinnitus, dim eyesight, hyperhidrosis, palpitation, unstable gait, soreness and fatigue of neck, weakness, anorexia, hypomnesis, dementia, depression, etc.

2. Cerebral ischemic stroke sequelae, including hemiplegia, are the most common cerebral thrombosis sequelae. The muscle strength of one limb is reduced, the limb is not active or can not be active at all. Often accompanied by sensory disturbances of the ipsilateral limb such as cold and heat, pain, etc. Sometimes with ipsilateral visual field defects; aphasia and exercise aphasia are expressed in that a patient can understand the words of others but cannot express his/her own meaning. Sensory aphasia is characterized by no language expression disorder, no understanding of others and their own utterances, and manifesting as "self-uttering" when they are answered. The named aphasia shows that one article can be seen, the purpose of the article can be spoken, but the name of the article cannot be called; a wide range or multiple relapses are also symptoms of cerebral thrombosis sequelae which can leave mental and intellectual disabilities: personality changes, negative pessimism, depression and depression of the body, listlessness, easy excitement, etc.; other symptoms are headache, dizziness, nausea, insomnia, dreaminess, inattention, tinnitus, dim eyesight, hyperhidrosis, palpitation, unstable gait, soreness and fatigue of the neck, weakness, loss of appetite, memory impairment, intolerance of noise, etc.

The most obvious performance is limb dysfunction, which affects later activities of patients, if rehabilitation training is timely and appropriate, more parts of limb functions can be recovered, if doctor-guided rehabilitation training is not timely performed, the limb functions before stroke happens, once the time exceeds half a year after the stroke happens, the actions and functions of the non-recovered limbs hardly recover later, and therefore timely limb assessment and rehabilitation training are needed.
