Hemiplegia, clinically known as hemiplegia, is a common symptom of acute cerebrovascular disease and refers to the motor impairment of the upper and lower limbs, facial and lower tongue muscles on the same side. Hemiplegia itself generally does not seriously affect life expectancy, and it is mainly the complications of the late development of hemiplegia that affect the life expectancy of patients. According to the degree of hemiplegia, it can be divided into mild hemiplegia, incomplete hemiplegia and total hemiplegia. The prominent symptom is the weakening of muscle strength, for example, a patient with mild hemiplegia can move around, showing weaker than normal muscle strength and a special gait, while a patient with incomplete hemiplegia has weaker muscle strength, and a patient with total hemiplegia is completely unable to move the affected limb, often bedridden and loses the ability to live. It is clear from this that hemiplegia affects the quality of life of the patient, but not the life expectancy. If a patient has swallowing problems in combination with hemiplegia, when choking on water, a mild cough may occur, while in severe cases, choking may cause choking and endanger life. At the same time, patients with hemiplegia tend to suffer from chronic underfeeding, which can make the body malnourished and may also affect survival time. In addition, for patients with severe hemiplegia who are unable to take care of themselves and need to be bedridden for a long time, complications such as intrapulmonary infection, decubitus ulcer, urinary tract infection and deep vein thrombosis of lower limbs may occur easily, and if these complications are not solved in time, relatively mild cases may only affect the quality of life, while serious cases may directly endanger life.
