The basic functional training of occupational therapy includes the following aspects: 1. Joint mobility training: mainly the training of upper limb joint mobility. As we all know, limb movement disorder is a typical symptom of cerebral palsy. Maintaining and expanding joint mobility can promote the development of upper limb motor function and allow patients to better master practical movements. 2. Training of head control: According to the order of normal pediatric gross motor development from top to bottom and from proximal to distal, head control is the earliest movement completed in motor development, and normal children can keep their head vertical and face in a neutral position 3 months after birth. In addition to the influence of head control on the motor development of the trunk and upper limbs, it is also very important for the development of respiration, feeding function, vision, hearing, etc., and should strive to complete early. Turning over is also an important stage in the development of motor function of children. Children with cerebral palsy, especially those with severe disease, do not have good head control function, and because of the influence of asymmetrical tension neck reflex, the trunk does not rotate when they want to turn over, so they need to be trained to turn over. Turning training can promote the completion of trunk rotation movement and promote the disappearance of asymmetric posture. Only when the turning movement is completed, the trunk straightening reflex can appear, and the flexion and support movements of the femoral and knee joints can be completed, so as to lay the foundation for sitting balance. 4. Sitting and balance training: Good sitting posture plays a vital role in correcting abnormal movement patterns and completing activities such as eating, communication and learning. Normally, children with normal development can sit alone at 6-7 months old, but children with cerebral palsy often lose the ability to sit up normally because of poor trunk and hip control. Balance training can help children with cerebral palsy to better master basic skills such as sitting, crawling, standing and walking. Therefore, sitting and balance training is an important part of occupational therapy for cerebral palsy. Crawling training is the first alternating movement that children with cerebral palsy are exposed to, and it plays a fundamental role in the future walking, compound movements and other sensory integration of children with cerebral palsy. 6. Hand function training and hand-eye coordination training: The purpose of occupational therapy is to enable the patient to recover maximum function, and the hand plays a big role in daily life, and coordination between the hand and the eye is also crucial. Most of the children with cerebral palsy have hand dysfunction, which is mainly caused by thumb inversion, clenched fist, wrist flexion, etc., as well as varying degrees of forearm internal rotation and scapular belt inversion, manifested as inability to grasp objects or insensitive and unstable grasp, i.e. no hand function or insensitive and uncoordinated hand function. The training of hand function is one of the features of occupational therapy, and we train the flexibility of hands and hand-eye coordination through various occupational activities. The ultimate goal of rehabilitation training is to let patients return to their families and society, and dressing, eating, combing hair and washing are the most basic daily activities that everyone must do. Children with cerebral palsy often have difficulty in completing these activities due to their own motor impairment, so training can improve their self-care ability. 7.Cognitive function training: Cognitive dysfunction is a common complication of cerebral palsy. For patients with cognitive dysfunction, we follow the model of guided education and adopt a group teaching method to conduct targeted training. The main training contents include memory, attention, logical reasoning, language, arithmetic, basic general knowledge and self-confidence development.
