Scholars all over the world have done a lot of work on the research of cerebral palsy, but because cerebral palsy is a relatively complex disease, there is no very complete, clear and precise definition that can be recognized by scholars from all countries so far. The second national conference on child rehabilitation and the ninth national academic conference on pediatric cerebral palsy rehabilitation held in Changsha in August 2006 adopted a new definition, typology and diagnostic criteria for cerebral palsy in China.
(I) Definition
Cerebral palsy is a syndrome caused by non-progressive brain injury and developmental defects from conception to infancy, mainly manifesting as motor disorders and postural abnormalities.
(II) Clinical typing
a) Spasticity (spastie): predominantly damaged cone system.
b) Dyskinetic (dyskinetie): The main cause of dyskinetic syndrome is damage to the extrapyramidal system, with increased dyskinetic movements. The symptoms include athetie, choreie, dystonie, tremor, etc.
c) Tonic (rigid): the main problem is the damage to the extrapyramidal system, with cogwheel and lead pipe-like persistent hypertonia.
d) Ataxia (ataxia): the main cause is cerebellar damage.
e) hypotonic.
f) Mixed types: The same child has two or more types of symptoms.
(c) Classification according to the site of paralysis
a) Monoplegia: A single limb is involved.
b) Diplegia: involvement of all four limbs, with the upper limb light and the lower limb heavy.
c) Triple palsy: three limbs are involved.
d) Hemiplegia: half of the limb is involved.
e) Quadriplegia: all four limbs are involved, with the upper and lower limbs involved to a similar degree.
(iv) Diagnostic conditions
a) The brain injury causing cerebral palsy is non-progressive.
b) The site of the lesion causing the motor disorder is in the brain.
c) The symptoms appear in infancy.
d) Mental retardation, epilepsy, perceptual disorders, communication disorders, behavioral abnormalities and other abnormalities may be combined.
e) Excluding central motor disorders due to progressive disease and temporary motor retardation in normal children.
