Cerebral palsy (CP) is a syndrome resulting from non-progressive brain injury and/or brain developmental defects from conception to infancy, mainly manifesting as central motor deficits and postural abnormalities. With the development of neonatal emergency medicine and the improvement of survival rate of preterm and low birth weight infants, there has been no significant downward trend in the incidence of cerebral palsy worldwide over the years. The clinical classification of cerebral palsy mainly includes spastic type, involuntary movement type, tonic type, ataxic type, hypotonic type and mixed type, among which spastic type accounts for 60-70%; according to the location of paralysis, it is divided into monoplegia, diplegia, trigeminal paralysis, hemiplegia and tetraplegia. Children with spastic cerebral palsy show increased muscle tone in the upper limbs as flexion, inversion, internal rotation, thumb inversion, fist clenching, hip flexion, knee flexion, lower limb inversion, internal rotation, cross, pointed foot, scissor step, etc.
