Official title
Bi-hemispheric Plasticity Elicited By Unilateral Finger Motor Training
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Recent studies suggest that when patients learn a new motor movement, it may cause a change in the way the nerves act in the area of the brain that controls that movement. This change is called use-dependent plasticity. The purpose of this study is to determine the direction and extent of the changes that take place in the brain areas that control movement in the untrained finger after the training of the opposite finger. The study outcomes may help researchers to develop rehabilitation strategies for people who have suffered brain injuries. Eighteen healthy adults age 18 years or older will be enrolled in this study. Participants will undergo a clinical exam and then come back to the Clinical Center three times for sessions that will last approximately 2 hours each. For each session, participants' forearms will be immobilized and a small electronic device will be attached to each index finger so that researchers can measure their movements. Participants will be asked to move either index finger and to observe and concentrate on its movement. Investigators will perform transcranial magnetic stimulation (TMS) before and after these motor exercises. For TMS, a wire coil is held over the scalp and a brief electrical current passes through the coil, creating a magnetic pulse that electrically stimulates the brain.
