Official Title: Event-Related fMRI Analysis of Patients With Ideomotor Apraxia During Transitive and Intransitive Hand Gesturing
Brief Summary:
Ideomotor apraxia, a disorder that affects patients with stroke and a variety of other brain lesions, features disturbed timing, sequence, and spatial organization of skilled movements. This study will look at how different areas of the human brain control fine hand movements.
Thirty-five participants 21 years and older will be enrolled in this study-25 healthy, right-handed people, and 10 stroke patients. They will undergo two outpatient sessions, each lasting up to 3 hours. The first visit for the stroke patients will occur between 2 weeks and 3 months after the stroke; the second visit will be at least 6 months after the stroke.
Participants will have a physical exam, give a medical history, and complete a questionnaire. Then they will undergo magnetic resonance imaging (MRI) scans. They will lie in the MRI scanner and will be asked to do a number of skilled hand movements using the right hand (such as pretending to use a hammer or waving goodbye) in response to directions that will appear on a screen mounted over their head. Their movements will be recorded on videotape during the procedures.
