| All participants presented with cerebral palsy with a main component of athetosis. |
|
| Cerebral palsy is characterized by a delay in motor development, spasticity, weakness of the limbs, athetosis, or ataxia. |
|
| Competing athletes have ataxia, hypertonia or athetosis, three impairment types that are most commonly associated with cerebral palsy. |
|
| Because of increased physical activity through involuntary movements, non-ambulatory children with athetosis are hyperactive and may have increased energy expenditure. |
|
| Noticeably brisk reflexes or clear differences in reflexes left versus right or minimum athetosis or ataxia with clear signs of cerebellar dysfunction. |
