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 the movement disorder, it can be divided into spastic, tardive dyskinesia, ataxia and other types. Spastic type: the lesion is in the cone bundle system, with increased muscle tone, restricted limb movement, increased passive movement resistance, folded knife spasm, hyperactive tendon reflexes, and positive pathological reflexes; tardive dyskinesia: the lesion is in the basal nucleus, with variable muscle tone, inconsistent motor willingness and motor results, and involuntary movements, and generally negative pathological reflexes, often accompanied by dysarthria; ataxia: the lesion is mainly in the cerebellum. Poor balance, of random movements, poor coordination, with intention tremor and nystagmus, and hypotonicity in movement; other types: flaccid type is dominated by hypotonia, rigid type shows increased motor resistance and leadpipe-like tonicity, and tremor type is dominated by the presence of resting tremor in the muscles. Treatment of cerebral palsy is divided into causal treatment, symptomatic treatment, rehabilitation treatment and surgery. 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. For patients with IQ ≥ 50%, age above 3 years, good physical condition, and who can cooperate with functional training after surgery, and who have not undergone other orthopedic surgery, we recommend patients to undergo SPR surgery.
