Cerebral palsy, or cerebral palsy, is usually a central movement disorder caused by non-progressive brain injury or abnormal brain development from various causes before birth to one month after birth. It is clinically characterized by abnormal posture and muscle tone, muscle weakness, involuntary movements and ataxia, and is often accompanied by sensory, cognitive, communication and behavioral deficits and secondary skeletal muscle abnormalities, and may be accompanied by seizures. The causes of cerebral palsy include prematurity, asphyxia, low birth weight, maternal-child blood type incompatibility, and genetics, etc. The incidence is about 2 per 1,000 in developed countries and about 1.5-5 per 1,000 in China. Clinically, according to the nature of movement disorders can be divided into: 1, spastic type: lesions in the cone bundle system, increased muscle tone, limb movement is limited, passive movement resistance is increased, there is a folding knife spasm, tendon reflexes are hyperactive, positive pathological reflexes; 2, hand and foot tachycardia: lesions in the basal nucleus, variable muscle tone, inconsistent movement will and movement results, there are involuntary movements, pathological reflexes are generally negative, often accompanied by Ataxia: the lesion is mainly in the cerebellum, with poor balance, poor coordination of random movements, intention tremor and nystagmus, and hypotonia in movement. 4. Treatment of cerebral palsy is divided into causal treatment, symptomatic treatment, rehabilitation treatment and surgical treatment. Surgical treatment includes selective posterior spinal nerve rhizotomy (SPR) and orthopedic surgical treatment. Selective spinal nerve rhizotomy is more effective for patients with spasticity and high muscle tone, and for patients with IQ ≥ 50%, age above 3 years, good physical condition, and who can cooperate with functional training after surgery.
