As a participant in the research study small sensors that are connected to wires will be affixed to points on your hand, wrist, elbow and/or shoulder. These sensors are painless and otherwise noninvasive. They will be used to measure the precise location of the hand and arm in space during the neurologic examination. This exam will test the tremors during short, simple tasks using the hand and arm. This information will be stored along with your name and medical record number for analysis after your testing is complete.
The sensors that are used to measure movements are connected to thin, flexible wires that will be attached with adhesive tape. The motion sensors use a magnet that produces a weak electromagnetic field. This electromagnetic field poses no direct harm, but could potentially interfere with medical devices such as cardiac pacemakers or deep brain stimulators if placed very close to the electromagnetic emitter.
