In the recovery period of stroke, the paralyzed limb can be incomplete paralysis, or the complete paralyzed limb has recovered some casual movement, at this time the paralyzed limb can carry out active training from simple to complex. 1. Active movement of a single joint: The patient concentrates on one joint, while the other joints are left to nature. For example: flexion and extension of the elbow joint, wrist and fingers can be flexed. 2.Simultaneous control of two joints: maintain one joint in a certain posture, for example, when making shoulder movements, maintain the elbow straight; when flexing the elbow, maintain the forearm rotated back; when moving the knee joint, maintain the ankle dorsal flexion, etc. 3. Gradually learn to control the whole limb: when there is progress in controlling two joints, pay attention to controlling three joints at the same time until the whole limb. For example: when the shoulder is abducted, straighten the elbow, rotate the forearm back, straighten the wrist and fingers; when the hip and knee are flexed, dorsiflex the ankle at the same time and prevent bad posture such as hip external rotation and foot inversion.
