Internal physiological conditions that determine the level of motor function in children with cerebral palsy include intramuscular coordination, coordination between muscles and muscle groups, abnormal levels of muscle tone, and joint mobility. The restoration of upper limb function is also an important issue that needs to be addressed for children with cerebral palsy. In the process of restoring upper limb function in children with cerebral palsy, no matter which method of treatment we apply, we must not neglect other factors that affect upper limb function, such as sensory, cognitive, and motor motivation, while paying attention to the problems of muscles, bones, and joints. And in the treatment using surgery or rehabilitation training, we must fully consider the specific situation of each child with cerebral palsy before deciding how to proceed: for example, children with hemiplegia have strong gross motor skills, so their fine motor skills of the hands may be given more attention, especially the coordination of the hands; while children with quadriplegia have more severe upper limb dysfunction, so grasp and release is the main training program, with the aim of improving daily living skills. Daily rehabilitation training can be based on physical therapy and occupational therapy, including biomechanical theory (orthotics, stage cast fixation, pulling, strength training, etc.), neurological and cognitive developmental theory (neurodevelopmental therapy, cognitive motor therapy, motor learning), and mandatory induction of movement therapy, etc. We analyze elbow support and two-handed support training as an example, and this movement is the basis for future knee-handed stance and This movement is the basis of the future knee-handed position and crawling of the child, and is also an important training to induce random movement of the upper and lower limbs. 1.Elbow support training The correct posture is that the shoulder and elbow line is perpendicular to the ground, the elbow joint is 90 degrees, and the head is raised, so that the child can use his or her elbows to support the weight of the upper body. If the child’s shoulder stability is poor, help should be given from the child’s two shoulders so that the child’s shoulder and elbow are in the correct position to complete the mastery of this posture. The therapist can push from one shoulder to the other side to facilitate the transfer of weight in the elbow-stand position. At the same time, the child can be trained to lower and raise the head evenly, to bend laterally to the sides and to rotate to the left and right. If the child has difficulty with head control, the therapist can gently apply appropriate stimulation at the back of the neck or between the shoulder blades. In more severe cases, a pillow or a cylindrical support can be placed under the chest to help support the child’s weight when he/she starts to stand on his/her elbow. 2.Hands support training The correct posture is to straighten the elbow joint and use the palms of the hands to support the weight, with the distance between the two hands as wide as the two shoulders and the fingers stretched out to the front. If the child’s upper limbs are poorly supported, the therapist can use both hands to support the child’s elbow joints and maintain a supportive posture of the upper limbs to prevent sudden bending of the elbow joints, or use a splint to maintain a supportive posture of the upper limbs. A pillow or cylindrical cushion can be placed under the child’s chest to induce the child’s chest and upper abdomen to leave the bed, as in the elbow position, so that the lower abdomen can be used to support the child’s body weight. The two-handed support should also emphasize head control training, upper limb support and weight transfer training. It is important to note that these training methods can be integrated according to the actual condition of the child with cerebral palsy, such as occupational therapy combined with acupuncture point injections to improve the fine motor function of the hand of the child with cerebral palsy. In addition to rehabilitation, the necessary surgical treatment is also important. The main purpose of surgical treatment is to relieve spasticity and spasticity-induced injury, thus improving the upper limb function of the child. The muscle tone is as close to normal as possible, and the patient’s painful muscle spasm can be solved in a long-term, stable and thorough manner, providing the prerequisite for maximum recovery of his motor function. In order to better achieve the purpose of improving the function of the upper limbs, the rehabilitation training after such surgery, especially the functional training with motivation is very important and should not be neglected.
