1, wasting syndrome: prolonged bed rest due to the fear of early activity being dangerous after the acute phase. As a result, restriction of active activities leads to muscle atrophy, osteoporosis, reduced neuromuscular reactivity and reduced cardiopulmonary function, etc. In addition, the existence and recurrence of various comorbidities and complications (such as pulmonary infection, urinary tract infection, decubitus ulcer, severe shoulder pain and other pain, etc.) cause the patient’s active activities to stop almost completely. After a long time, a serious “disuse state” is formed. 2, misuse syndrome: Although many patients and medical workers recognize that active training should be carried out earlier, but due to the lack of proper rehabilitation knowledge, they are obsessed with upper limb pulling, grip strength and lower limb straight leg raising training, and early racking of patients to “walk”…. …, the result is to aggravate the anti-gravity muscle spasm, seriously affect the development of active movement to casual movement, and make the joint reaction, common movement, spastic movement pattern reinforced and fixed, so the formation of “misuse state”. 3. Overuse syndrome: Some patients are so anxious after stroke that they try to train desperately, such as walking with hemiplegic gait excessively, which causes synovitis of the knee joint on the healthy side and even hydrocele of the knee joint. The purpose and significance of rehabilitation treatment: 1. To prevent the occurrence and development of secondary disorders after stroke and traumatic brain injury. 2.It can actively prevent the occurrence of complications such as muscle atrophy, joint stiffness, and decubitus ulcers 3.Maintain cardiopulmonary, and circulatory functions, promote the recovery of their dysfunction, and lay the foundation for future systematic rehabilitation. 4.Significantly improve the efficacy of stroke. 5.Greatly reduce the rate of disability. 6.Significantly improve the quality of life of stroke patients, and enable them to return to society as soon as possible. 7.Restore patients’ ability to take care of themselves as soon as possible and reduce the burden of family and society, thus having great social and economic benefits. Why should early rehabilitation be advocated? Along with drug treatment, early rehabilitation can speed up the recovery of limb function, prevent complications, prevent joint deformities and muscle contractures, and improve the quality of patients’ daily life. When is the most appropriate time to intervene in rehabilitation? The time to start early rehabilitation: Immediately after stroke, rehabilitation, maintenance of good limb position, position change (turning) and appropriate passive limb activities are feasible as long as they do not interfere with resuscitation, while assisted and active training should be started 48 hours after the patient is conscious, the vital signs are stable and the mental symptoms no longer progress. Therefore, it is best to receive systematic and standardized rehabilitation training methods in the hospital before training at home.
