When a patient loses the active function of the joint for a long period of time, joint stiffness will occur, and muscle atrophy will occur, resulting in joint deformity. In order to prevent deformity, the patient should first be helped to fully mobilize the muscles with active function. For example, for patients with lower limb paralysis, they should exercise the upper limb muscles diligently; for patients with partial lower limb paralysis, the functional muscles should be fully exercised so as to minimize muscle atrophy and also to prevent various complications. For joints that cannot be actively moved, nursing staff is needed to help passive movement to prevent the occurrence of deformities. To prevent foot drop, both lower limbs can be padded with soft pillows to maintain the functional position of the limbs and 90 degrees of foot dorsiflexion. The foot can also be pulled with a strap to keep the knee joint in a functional position of 10-15 degrees of flexion. Move the joints daily, such as toe joints, ankle joints, knee joints and hip joints, and massage the muscles for about 15 minutes twice a day to promote lymphatic and blood circulation and prevent joint stiffness, stiffness and muscle atrophy. At the same time, attention should be paid to fully mobilize the patient’s subjective initiative, so that the patient can fully understand the importance of relying on their own hard work and actively participate in exercise.
