1. Spastic cerebral palsy: It accounts for more than 60% of cerebral palsy. It is characterized by spasticity and stiffness of limb muscles. Due to the damage of the brain, the inhibition of the lower nerves (spinal cord and peripheral nerves) is reduced or disappeared, resulting in the overexcitation of the lower nerves (enhanced pull reflex), causing the muscles to spasm. The main manifestations of the upper extremities are flexion of the elbow, flexion of the wrist, inversion of the thumb, and inability to straighten the flexion and extension of other fingers. In the lower extremities, the main manifestations are crossed legs (scissor stance), flexed hips (bent buttocks), flexed knees (legs not straight), inability to land on the heels, inward turning of the feet, and flexed or upward turning of the toes. This type of cerebral palsy is most suitable for surgical treatment. 2.Hand and foot motility cerebral palsy: It accounts for about 20% of cerebral palsy. This type of cerebral palsy is characterized by involuntary movements of the limbs, including facial expressions, which are difficult to control by will. The vocal and phonological organs are also involved, so there is often a speech impairment. The brain damage is located in the basal nucleus and the extrapyramidal system. This type of cerebral palsy is suitable for carotid peri-sympathetic nerve net stripping. 3.Ankylosing cerebral palsy: It manifests as a state of rigidity of the limbs, with resistance to both flexion and extension, and difficult activities. 4.Dystonic cerebral palsy: Due to the damage of cerebellum and brainstem, it causes the balance dysfunction. The child cannot complete correct movements, such as unstable walking, uncoordinated and inaccurate movements, and malfunctioning of pronunciation tuning gate. It is often accompanied by mild tremor of the hands, head and eyes. 5.Tremor-type cerebral palsy: It is manifested by involuntary and rhythmic shaking of a certain part of the body. It is extremely rare, but can be seen occasionally in tardive dyskinesia cerebral palsy. 6. Hypotonia cerebral palsy: It is characterized by generalized weakness, muscle flaccidity and no random movement. It is often a precursor to spastic cerebral palsy and tardive dyskinesia. 7. Mixed cerebral palsy: It refers to the coexistence of several types of cerebral palsy mentioned above.
