Freud also made a rough correlation between the location of the problem inside the brain and the location of the affected limbs on the body and documented the many kinds of movement disorders.In the early 20th century, the attention of the medical community generally turned away from CP until orthopedic surgeon Winthrop Phelps became the first physician to treat the disorder. He viewed CP from a musculoskeletal perspective instead of a neurological one. Phelps developed surgical techniques for operating on the muscles to address issues such as spasticity and muscle rigidity. Hungarian physical rehabilitation practitioner András Pető developed a system to teach children with CP how to walk and perform other basic movements. Petős system became the foundation for conductive education, widely used for children with CP today. Through the remaining decades, physical therapy for CP has evolved, and has become a core component of the CP management program.In 1997, Robert Palisano et al. introduced the Gross Motor Function Classification System (GMFCS) as an improvement over the previous rough assessment of limitation as either mild, moderate, or severe. The GMFCS grades limitation based on observed proficiency in specific basic mobility skills such as sitting, standing, and walking, and takes into account the level of dependency on aids such as wheelchairs or walkers. The GMFCS was further revised and expanded in 2007. Society and culture

It is difficult to directly compare the cost and cost-effectiveness of interventions to prevent cerebral palsy or the cost of interventions to manage CP.
Machine learning algorithms facilitate automatic early diagnosis, with methods such as deep neural network and geometric feature fusion producing high accuracy in predicting cerebral palsy from short videos. It is a developmental disability.Once a person is diagnosed with cerebral palsy, further diagnostic tests are optional. Neuroimaging with CT or MRI is warranted when the cause of a persons cerebral palsy has not been established. An MRI is preferred over CT, due to diagnostic yield and safety. When abnormal, the neuroimaging study can suggest the timing of the initial damage. The CT or MRI is also capable of revealing treatable conditions, such as hydrocephalus, porencephaly, arteriovenous malformation, subdural hematomas and hygromas, and a vermian tumour (which a few studies suggest are present 5–22% of the time). Furthermore, an abnormal neuroimaging study indicates a high likelihood of associated conditions, such as epilepsy and intellectual disability. There is a small risk associated with sedating children to facilitate a clear MRI.The age when CP is diagnosed is important, but medical professionals disagree over the best age to make the diagnosis. The earlier CP is diagnosed correctly, the better the opportunities are to provide the child with physical and educational help, but there might be a greater chance of confusing CP with another problem, especially if the child is 18 months of age or younger. Infants may have temporary problems with muscle tone or control that can be confused with CP, which is permanent.
