The main methods of rehabilitation training for the hemiplegic side of the arm in cerebral infarction patients include the following: 1. Patients are encouraged to lie on the affected side as much as possible, and the affected arm can be placed on a small pillow, taking care not to be pressed. 2. The shoulder, elbow and wrist joints can be moved passively at least twice a day for at least 15 minutes each time. The joint mobility is kept at about 10° less than the normal mobility. 3. Progressive impedance training and isometric muscle training are performed for the affected arm muscles. 4. Functional electrical stimulation therapy and myoelectric biofeedback therapy can be performed for the arm muscles to improve the muscle strength and function of the paralyzed arm. 5. In addition, the function of the affected arm can be restored by means of Tui Na, massage, acupuncture and physiotherapy. 6, If the patient has muscle stiffness and tonicity in the arm, ethylparisone, baclofen and local intramuscular injection of botulinum toxin can be given to release muscle spasm.
