There is no quick way to recover the function of the left hand in hemiplegia, and the following muscle strength training, joint mobility training, sensory training, and daily life ability training should be carried out according to the recovery situation and in accordance with the principle of gradual progression. 1. Muscle strength training: through grasping, finger-pairing and other finger training, the muscle control of fingers and finger strength can be increased. 2. Joint mobility training: some patients have high muscle tone in the early stage of hemiplegia, which leads to limitation of finger extension, joint mobility training should be carried out to relieve the contracture of the tissues around the joints. 3. Sensory training: Usually hemiplegic patients have abnormal sensory nerves, so the patient’s hands should be stimulated with sensory stimulation, such as alternating hot and cold water brushing, tape wrapping, pinching and kneading, etc. to help the recovery of sensory function. 4. Daily life ability training: fine hand function training such as screwing screws, using chopsticks to hold beans, etc. should be provided to patients to increase the control of fine movements and improve the ability of independent living. Hand dysfunction in hemiplegia should be trained as early as possible under the guidance of rehabilitation doctors to prevent delaying the condition.
