Answer

Patients with spastic (pyramidal) cerebral palsy evidence spasticity (ie, a velocity-dependent increase in tone) and constitute 75% of patients with cerebral palsy. Patients have signs of upper motor neuron involvement, including hyperreflexia, clonus, extensor Babinski response, persistent primitive reflexes, and overflow reflexes (crossed adductor). This may be observed by the child's tendency to keep the elbow in a flexed position or the hips flexed and adducted with the knees flexed and in valgus, and the ankles in equinus, resulting in toe walking.
