Protocol Number: 08-N-0212
People with mild to moderately severe Parkinson's disease who are between 40 and 80 years of age and whose main problems are slow movement and stiffness may be eligible for this study. Participants undergo the following tests and procedures: - Random assignment to real or placebo (sham) iTBS treatment. - iTBS sessions (real or sham) 4 times a week for 2 consecutive weeks. For this test, the subject sits in a comfortable chair. A wire coil is held on the subject's scalp, and a brief electrical current is passed through the coil, creating a magnetic pulse that stimulates the brain. The subject hears a click and may feel a pulling sensation on the skin under the coil. There may be a twitch in the muscles of the face, arm or leg. - Test of gait (walk), hand and arm movements before and after each session. The gait test requires walking 10 meters (about 30 yards) in the same corridor with the same shoes. - Extended testing. The first and last gait tests (done before starting iTBS and after the eighth session) require coming off any Parkinson's medication for at least 12 hours before the test. On these test days, subjects also undergo a clinical examination, short neuropsychological test battery, a computer-based reaction time test and depression and quality-of-life rating scales. These procedures are repeated in a follow-up visit 1 month after the last session.
