Speech impairments like dysarthria are common in children with cerebral palsy (CP) which can greatly affect participation across environments. Our study examined how speech impairment severity changes over time in 101 children with CP at 4, 6, 8, and 10 years of age.

Cerebral Palsy affects body movement, muscle control, muscle coordination, muscle tone, reflex, posture and balance. Depending on the part of the brain that is injured depends on how someone’s muscle tone will be effected. For people with spastic CP they have increased muscle tone because of the part of the brain that's injured. If causes very tight muscles which in turn effects the movement of the joints and of the limbs. For others who have dyskinetic CP they lose the ability to have voluntary control over their muscles, and they can have jerky and uncontrolled movement patterns.
