Study Summary
This study will determine how the brain controls movements by sending messages to the spinal cord and muscles. Researchers want to know if strengthening a hand muscle will increase the strength of the same muscle in the other hand, and if these changes happen in the brain or spine, or both. Plasticity in this study refers to the capacity for continuous changes of the neural pathways in the brain and nervous system. Researchers have seen cases in which using a muscle extensively (force production) in one muscle group has increased the strength of the same muscle group on the opposite side of the body (force transfer). This situation happens without the unused muscle becoming larger-suggesting that the practice causes changes in some parts of the brain or spine. It is vital for scientists to know how this effect works, so that they can create new rehabilitation methods for people who cannot move or who have difficulty moving one side of their body. Patients ages 18 to 60 who are in good health and who do not have a history of major conditions affecting the bones, joints or nervous system may be eligible for this study. Patients will undergo a medical examination. There will be 1 or 2 testing sessions, 20 training sessions, and 1 or 2 final testing sessions, with patients being asked to come to the laboratory for as few as 4 times (about 10 hours total) or for up to 25 visits (about 20 hours total). The investigator will indicate which of six different groups that a patient is selected for. During testing sessions, the strength of the pointer and little fingers in each hand will be determined through the use of very brief electrical pulses. There also will be transcranial magnetic stimulation (TMS) and 1 Hz TMS. The researchers will place one or two wire coils on the patient's scalp and make marks on the scalp which will be removed at the end of the session. During the TMS, a brief electrical current is passed through the coil, creating a magnetic pulse that stimulat
