The term “cerebral palsy” is used when the cerebral insult has occurred before birth, around the time of birth or up to the age of about 3 years, while the brain is still undergoing rapid development. Disorders of movement and posture are caused by damage to the motor cortex. In addition to postural and motor abnormalities, which are always present, people with CP may exhibit learning disabilities, other cognitive and sensory impairments, hearing and visual loss, speech and language disorders, emotional problems, orthopaedic complications and epilepsy. The consequences of chronic muscle imbalance and the resultant deformities can cause increasing disability with age. One of the most significant problems in children with CP is defective postural control.
