Ideomotor Apraxia Clinical Trial
Official title:
EEG Analysis of Ideomotor Apraxia
This study will examine how the brain operates during execution and control of voluntary
movement and what goes wrong with these processes in disease. It will use
electroencephalography (EEG) and electromyography (EMG) to compare brain function in normal
subjects and in patients with-a disorder affecting patients with stroke and other brain
lesions. These patients have problems with timing, sequence and spatial organization of
certain types of movements.
EEG measures the electrical activity of the brain. The activity is recorded using wire
electrodes attached to the scalp or mounted on a Lycra cap placed on the head. EMG measures
electrical activity from muscles. It uses wire electrodes placed on the skin over the
muscles.
Adult healthy normal volunteers and patients with ideomotor apraxia with a single left brain
lesion may be eligible for this study.
Study participants will be asked to make certain movements with their arms or hands, such as
waving and using scissors. Brain and muscle activity will be measured during these tasks
with EEG and EMG recordings. Patients may be asked to repeat these tests over time as their
condition changes (such as during recovery from a stroke) to gain information about the
recovery process.

Eligibility |
We will study normal volunteers and patient groups between the ages of 18-80 years of age
within the following parameters: INCLUSION CRITERIA: Normal subjects. Patients diagnosed with Ideomotor apraxia with a single left hemisphere lesion. Patients with Ideomotor apraxia with corticobasal ganglionic degeneration. EXCLUSION CRITERIA Normal subjects: abnormal neurologic examination or history of neurologic disorders. Ideomotor apraxic patients: a second neurologic disorder including more than one brain lesion or the inability to cooperate fully. Normal and Ideomotor apraxic patients: cognitively impaired subjects will not be accrued (for the purposes of this study, patients that can provide full informed consent for the study are not considered cognitively impaired). For MRI studies, patients with metallic implants to remove potential risks from this procedure. For MRI purposes, women who are pregnant are excluded from this part of the protocol. Therefore, all women of childbearing potential will have a pregnancy test performed, which must be negative, before proceeding. |
