Pediatric cerebral palsy typology: Clinical typology: 1. spasticity: predominantly cone system loss. 2. involuntarymovement: loss of the external F-body system is the main cause, with increased involuntary movement. The manifestations are athetosis, choreic movements, dystonic, tremor, etc. 3.Tonic type (rigidity): the loss of the extrapyramidal system is the main cause, with cogwheel and lead pipe-like persistent hypertonia. 4, ataxia (ataxia): mainly cerebellar damage 5, hypotonic underground type (hypotonic) 6, mixed type (mixedtype”): the same child shows two or more types of symptoms. The type of paralysis is divided according to the site: 1. monoplegia: a single limb is involved. 2.Diplegia: all four limbs are involved, with the upper limbs light and the lower limbs heavy. 3.Triplegia: three limbs are involved. 4.Quadriplegia: The four extremities are involved, and the upper and lower extremities are involved to a similar extent. 5.Hemiplegia (hemiplegia): half of the limbs are involved. Diagnostic conditions: 1. The injury causing cerebral palsy is non-progressive. 2. The site of the lesion causing the movement disorder is in the brain. 3. The symptoms appear in infancy. 4. Mental retardation, epilepsy, perceptual disorders, communication disorders, behavioral abnormalities and other abnormalities may be combined. Central dyskinesia and temporary motor retardation in normal children are not caused by progressive diseases.
