Chart Review: Central Motor Conduction Time in Neurological Disorders

Background: TMS stands for transcranial magnetic stimulation. It is a non-invasive way to stimulate the brain. It helps researchers study the nervous system. TMS can assess central motor conduction time (CMCT). That can be used to diagnose some diseases. It can also show how well treatments are working. Researchers want to study the records of people who have already had TMS. They want to see how it relates to the results of diagnostic studies. Objectives: To study the results of transcranial magnetic stimulation in certain neurological disorders. To create a descriptive analysis of the results. Eligibility: Records that are already in the NINDS database Design: The study will not enroll any participants. Researchers will search the database for certain terms. These include TMS, CMTC, and motor evoked potentials. This will identify records of people who had TMS for diagnosis. Using data from the records, researchers will calculate CMCT. They will note other data that relate to CMCT. Researchers will analyze their findings. They will write a review article. Personal data will be removed from all the records before the findings are analyzed.
