Cerebral palsy can have the following symptoms depending on the clinical typology: i. Spastic quadriplegia: Damage to the cone system is predominant, including damage to cortical motor areas. Hyper-retractile reflex is the characteristic of this type. Increased muscle tone of the extremities, dorsal extension, inversion and internal rotation of the upper extremities, inversion of the thumbs, forward flexion of the trunk, inversion, internal rotation, crossover of the lower extremities, knee flexion, scissor gait, pointed foot, inward and outward turning of the foot, arching back sitting, hyperactive tendon reflexes, ankle clonus, folding knife sign and conus fasciculus sign, etc. Spastic diplegia: The symptoms are the same as those of spastic quadriplegia, but the spasticity and dysfunction of both lower limbs are heavier than those of both upper limbs. Spastic hemiplegia: The symptoms are the same as those of spastic quadriplegia, but it is manifested in one limb. The most obvious features of this type are asymmetrical posture, involuntary movements of the head and limbs, i.e. a lot of redundant movements are often interspersed with certain movements, and the limbs and head keep swaying, making it difficult to control oneself. This type of muscle tone can be high or low, and can change with age. The tendon reflexes are normal and the extrapyramidal signs are TLR(+) and ATNR(+). Hypotonia at rest. Ataxia: The cerebellum is predominantly damaged, as well as the cone system and extrapyramidal injuries. The main characteristic is uncoordinated movement due to motor sensory and balance sensory impairment. In order to obtain balance, the two feet are separated far from each other, the gait is staggering, and the directionality is poor. The movements are clumsy and uncoordinated, and there may be intentional tremor and nystagmus, balance impairment, standing with the center of gravity at the heel, wide base, drunkard’s gait, and body stiffness. Muscle tone may be low, slow motor speed, little head movement, and poor detachment movements. Closed eyes and difficult to stand sign (+), finger-nose test (+), normal tendon reflex. Sixth, mixed type: with the characteristics of more than two types.
