There are many factors that influence the consequences of functional recovery after stroke. The following factors, for example, can have a significant impact on the recovery of motor function: 1. 3. nature: in terms of the difficulty of recovering motor function after hemiplegia, infarction > hemorrhage > embolism; 4. the degree of timely and correct medical treatment timely and correct treatment after the onset of the disease can control the further aggravation of the disease, timely and maximum protection of the remaining brain tissue, and even save part of the damaged neural tissue (such as timely thrombolysis can save a large number of neurons that may be dying due to ischemia). The prevention and control of complications can create extremely good conditions for rehabilitation treatment. 5.Patients with severe speech and communication disorders who cannot cooperate with active rehabilitation training will seriously affect the recovery of hemiplegia; 6.Patients with severe cognitive dysfunction, such as severe dementia or severe neglect, will greatly delay the recovery of motor function; 7.Patients with severe complications who have to undergo complex clinical treatment, such as severe aspiration pneumonia 8. Whether the rehabilitation treatment is timely and accurate, if it causes serious “disuse syndrome”, “misuse syndrome If it causes serious “disuse syndrome”, “misuse syndrome” or overuse, it will be very difficult for hemiplegic patients to recover their movements; 9. The patient’s ability to tolerate physical activities In intensive rehabilitation training, the effectiveness of rehabilitation medical treatment is time-dependent and dose-dependent. If the patient’s physical strength cannot withstand the appropriate time and dose of rehabilitation training, he/she cannot expect a rapid recovery of motor function; 10. Time of limb weakness Generally, the muscle tone of the hemiplegic limb turns from very low to high after 2-4 weeks. The recovery of motor function is poorer in patients with long-term low muscle tone of the affected limb.
