About this trial
Background:
\- Two ways to study the brain while people are moving are near-infrared spectroscopy (NIRS) and electroencephalography (EEG). NIRS uses light to look at blood flow in the brain when it is active. EEG records electrical activity in the brain. Both have been used safely for many years, even in very young children. NIRS or EEG can be used while a person is moving to show which parts of the brain are the most active. Researchers want to use NIRS and EEG to study brain activity during movement in people with cerebral palsy and healthy volunteers. Learning more about how people with and without cerebral palsy use their brain to control their muscles may lead to new ways of training people with cerebral palsy to move better.
Objectives:
\- To study how the brain controls body movement in people with and without cerebral palsy.
Eligibility:
* Individuals at least 5 years of age who have cerebral palsy. * Healthy volunteers at least 5 years of age.
Design:
* This study has three parts. People with cerebral palsy will be selected for all three. Healthy volunteers will be asked to do only two of them. Everyone who participates will have NIRS and/or EEG exams during movement. People with cerebral palsy may also have biofeedback sessions to train coordination of movement and brain activity. * Participants will be screened with a physical exam and medical history. Urine samples may be collected. * All participants will have at least one session of NIRS and/or EEG imaging studies. Sessions may also include the following tests: * Magnetic resonance imaging to look at the brain * Electromyography to measure electrical activity of the muscles * Motion analysis of specific body parts * Ultrasound to measure activity of the muscles * Motorized, robotic, and electrical stimulation of the muscles * Other clinical tests of muscle movement as needed. * Participants with cerebral palsy will have biofeedback sessions. These sessions will help them learn to coordinate muscle movement and brain activity.
Eligibility criteria
Qualifiers
* Age 5 years and older
Surgery free for six months in either the upper or lower extremities.
Free from botulinum toxin injections within four months in either the upper or lower extremities.
Either a healthy volunteer or have a diagnosis of a childhood-onset (before 13 years of age) brain injury resulting in motor impairment of one arm and one leg on the same side of the body or motor impairment of both legs or have a diagnosis of childhood-onset (before 13 years of age) peripheral injury resulting in sensory or motor impairment of any limb or multiple limbs.
Disqualifiers
Any neurological, musculoskeletal or cardiorespiratory injury, health condition, or diagnosis other than childhood-onset brain or peripheral injury that would affect the ability to mentally concentrate or move a body part repetitively for short periods of time. Examples of this include, but are not limited to, congestive heart failure, end stage cardiac disease, or fractures that have not completely healed.
Uncontrolled seizures.
Concurrent use of medicines for muscle tone (e.g., baclofen, trihexyphenedyl, dantrolene sodium, tizanidine, or carbidopa/levodopa). If patients are taking these medications daily, the treating physician will be contacted by the MAI to determine if it is acceptable for the subject to temporarily discontinue the medication(s) for 24 hours prior to participating in testing for this study for each of the first 2 objectives. If that is not deemed to be safe, the subject will be excluded. Subjects who are on these medications will not be allowed to participate in Objective 3.
Pregnancy: Childbearing potential will be determined during the history and physical exam and urine pregnancy test may be required
