Background

Hemiplegia refers to the movement disorder of the upper and lower limbs, facial muscles and lower part of the tongue muscle on the same side, and is a common symptom of acute cerebrovascular disease. Although the mild hemiplegia patients can move, walking up and walking usually causes the upper limbs to bend and the lower limbs to straighten, and the paralyzed lower limbs draw half a circle by one step, which is called the hemiplegic gait. Serious patients are bedridden and lose life ability. According to the degree of hemiplegia, it can be classified into paresis, incomplete paralysis and complete paralysis. Paraplegia: the muscle strength is weakened, the muscle strength is in 4-5 grades, the daily life is not affected generally, incomplete paralysis is heavier than paraplegia, the range is larger, the muscle strength is 2-4 grades, and the total paralysis is as follows: muscle strength is 0-1 grade, and the paralyzed limbs can not move completely. The patient can also carry out some daily activities for the patients with paraplegia and incomplete paralysis, but the hemiplegic limb can be affected, the activities are inconvenient, and the patient is often fixed by an external device, meanwhile, the patient with paraplegia and incomplete paralysis is actively rehabilitated or has great possibility of rehabilitation, but the common fixing devices on the market at present often do not have the rehabilitation training capacity, or only have the less-efficient rehabilitation effect, and only can carry out one-way mechanical reciprocating motion, and the rehabilitation effect is more general.
