Rehabilitation is the return of the disabled person to a pre-disability similar social environment and to a proper social role. This requires that patients receive medication along with active functional training of the residual limb. Due to the small number of medical and nursing staff in the Department of Rehabilitation Medicine, patients cannot be treated on a one-to-one basis, so the majority of the time spent on functional training is supervised by a chaperone. The supervision and guidance work undertaken by the chaperone is actually a continuation of the rehabilitation functional training provided by the medical and nursing staff to the patient, so that the patient’s training is carried out on a daily basis without interruption and the training effect is quantified in the process of repeated reinforcement. The degree of support and attention given to the patient’s functional training by the caregiver directly affects the effect of the patient’s functional training. In addition to rehabilitation care, medical staff should educate and guide the patient’s chaperone about the disease, so that the chaperone can understand the condition and training requirements in a timely manner, so that when assisting the patient in functional training, it is scientific, accurate, standardized, and not too hasty or blindly increasing the intensity of activities, and avoiding the emergence of Wu-use and over-use syndrome, which is a very important part of rehabilitation care. Whether the patient can adhere to the planned functional training daily is closely related to the cognitive level, degree and role of the accompanying nurses. Therefore, in order to improve the quality of comprehensive rehabilitation of hemiplegic patients, it is necessary to do a good job of educating the companion about the disease and teaching the companion to master the basic movements of rehabilitation, and to involve the companion in the development and implementation of the patient’s rehabilitation training plan.
