This study will examine how the brain controls eye-hand coordination (visuomotor skills) in children with spastic diplegia and will determine whether impairment of this skill is related to the learning difficulties in school that some of these children experience. Spastic diplegia is a form of cerebral palsy that affects the legs more than the hands. The brain injury causing the leg problem in this disease may also cause difficulty with eye-hand coordination.
Healthy normal volunteers and children with spastic diplegia between 6 and 12 years of age may be eligible for this study. Candidates will be screened with a review of medical and school records, psychological testing, neurological and physical examinations, and assessment of muscle function in the arms and legs.
Participants may undergo one or more of the following procedures:
Neuropsychological testing (1 to 2 hours) - involves sitting at a computer and answering questions, such as whether the letters on the screen make up a real word.
Magnetic resonance imaging (MRI) (45 minutes) - uses a strong magnetic field and radio waves to provide images of the brain. The child lies on a table in a narrow cylindrical machine while the scans are obtained. Both the child and parent wear earplugs to muffle the loud noise the radio waves make while the images are formed.
Electroencephalography (EEG) and electromyography (EMG) (1 to 2 hours) - EEG uses electrodes to record the electrical activity of the brain. The electrodes are in a special cap that is worn on the head during the procedure. EMG records electrical activity from muscles. Electrodes are placed on the skin over certain muscles. During the test, the child makes simple repetitive movements, such as finger tapping. The cap and the electrodes on the skin are removed at the end of the test.
