Here we introduce the methods of elbow joint mobility training for children with cerebral palsy. 1.Objective: To increase the mobility of the joint and improve the independent control of the elbow joint in children with cerebral palsy. To correct the flexor spasm of the elbow joint, and to achieve normal function of flexion and extension, prerotation and postrotation of the joint. 2. Significance: It is impossible to train hand fine motor function in children with cerebral palsy who do not have correct upper limb gross motor function. Therefore, training of gross motor skills is performed first until fine motor can be well maintained. At the same time, children with cerebral palsy are given the opportunity to experience different sensations in the hands and strengthen the cognitive training of the hands and eyes. 3. Methods: 1) Elbow flexion and extension training: The therapist helps the child with cerebral palsy to perform passive or active elbow flexion and elbow extension training. The intensity of the training gradually increases, the amplitude of joint flexion and extension gradually increases, and the number of flexion and extension training gradually increases. For children with spastic cerebral palsy, elbow extension training should be the main focus. Let the child lie prone on the Bobath ball, extend the scapular band forward, and extend the elbow to retrieve an object, or hold a hard cone-shaped object to touch a target in front of the table. The child with cerebral palsy holds a column with a magnet at one end to retrieve a metal object placed on the table, with movements that involve straightening the elbow. For young children with cerebral palsy, sit them on their laps and let them reach out to pat the therapist’s palm, taking care not to lose postural control. (2) Weight-bearing training of elbow joint: Prone support training: the child with cerebral palsy lies prone, supports his body with both upper limbs, the therapist holds his lower limbs up, and after maintaining balance, the child with cerebral palsy uses both upper limbs alternately to carry out weight-bearing training of elbow flexion contracture: the child takes a sitting position, the therapist is located on the side of the child, holds his hand through the palm of the child, pulls this side of the upper limb to 45o of abduction, and uses the other hand to assist the child’s elbow joint to make it fully extend. Then, with the hand that assists the child’s elbow joint, the therapist holds the thumb of the hand of the child with cerebral palsy and extends and abducts the thumb. The remaining four fingers are extended and placed flat on the table on the side of the child’s body, and finally the upper limb on the opposite side is lifted so that the weight is shifted to the upper limb on the supporting side. (3) Pre-rotation and post-rotation training of the elbow joint: Passive activity extension and flexion method: First, make the forearm of the child with cerebral palsy rotate forward, use the pendulum shaking method, hold the affected arm with both hands or one hand and do small up and down continuous shaking with light force to relax the muscles around the joint, and then grasp the wrist with one hand for the practice of extraction, extension and flexion. Take a sitting position with the feet flat on the ground. The therapist grasps the child’s elbow with one hand, fixes the elbow joint, and holds the child’s ipsilateral hand with the other hand (the two thumbs are interlocked), then rotates the forearm back, pushes it upward for flexion, then pulls it downward for extension, and repeats the exercise. For those with high muscle tone and severe spasticity, the child should be restrained from overexertion in a slow, balanced and orderly manner, and be guided by the situation to make spontaneous flexion and extension activities. Let the child with cerebral palsy take the initiative to train the forearm to rotate backward and forward, such as unscrewing the handle of the door of the house. Repeated active training will achieve better results. (4) Pulling training of elbow joint: – Pulling training of elbow flexion contracture: The child with cerebral palsy is seated, firstly, the therapist holds the child with one hand through the palm and pulls the shoulder joint forward 90o, then the therapist assists the child with the other hand to fully extend the elbow joint, then the child’s wrist joint is dorsiflexed 90o with the hand that holds the child with cerebral palsy, and at the same time, the child is prompted to push forward. Push and hold the child in this position for several minutes and repeat the training. -The therapist first taps the back of the child’s hand from the ulnar side to the radial side. After the tension in the hand is slightly relieved, the therapist holds the child’s thumb in one hand and pulls it outward, while the other hand holds the remaining four fingers to make them extend.
