These conditions are best treated by multidisciplinary approach which includes pediatricians, pediatric orthopedics, physiatrists, neurologists or neurosurgeons, and possibly urologists. Cerebral Palsy Definition Non-progressive (static) injury to the growing brain. This injury must result in postural or movement disorder. The insult has to occur early in the development of the child’s brain (prenatal, perinatal or early post-natal). Despite that the injury to the brain is non-progressive, the musculoskeletal mani- festation of cerebral palsy may progress with time. A.
