User-friendliness of a Portable Driving Simulator

The use of simulators to retrain driving skills of patients with stroke, Parkinson's disease (PD), or multiple sclerosis (MS) is very limited because of cost, space required, and incidence of simulator sickness in high fidelity simulators. The Principal investigator recently developed a low cost low fidelity portable driving simulator (PDS). In this pilot study, the study team will (1) determine the ease of use and occurrence of simulator sickness while operating the low fidelity PDS in a clinic setting and (2) the efficacy of the low fidelity PDS to reproduce the benefits from retraining impaired driving skills of stroke survivors in a high-fidelity simulator. Participants: 30 participants, separated according to neurological condition including stroke, PD, or MS, will be randomly allocated to either the PDS or fixed-base high-fidelity simulator training. Each participant will undergo a pre-training evaluation, five hours of designated training and a post-training assessment, similar to the pre-training evaluation. Data will be analyzed according to study aims. The investigators hypothesize that the simple set up of the PDS will make it easier to use and better decrease the incidence of simulator sickness that typically leads to stopping therapy than the high-fidelity simulator. The investigators hypothesize that improvements in lane maintenance, adherence to speed limits, reaction to traffic lights, and overall reaction time after training using the PDS will not be significantly different from improvements observed after training using the high-fidelity driving simulator.

Influence of Brain Oscillation-Dependent TMS on Motor Function

Background: When people have a stroke, they often have difficulty moving their arms and hands. Transcranial magnetic stimulation (TMS) can improve how well people with and without stroke can move their arms and hands. But the effects of TMS are minor, and it doesn t work for everyone. Researchers want to study how to time brain stimulation so that the effects are more consistent. Objective: To understand how the brain responds to transcranial magnetic stimulation so that treatments for people with stroke can be improved. Eligibility: Adults ages 18 and older who had a stroke at least 6 months ago Healthy volunteers ages 50 and older Design: Participants will have up to 5 visits. At visit 1, participants will be screened with medical history and physical exam. Participants with stroke will also have TMS and surface electromyography (sEMG). For TMS, a brief electrical current will pass through a wire coil on the scalp. Participants may hear a click and feel a pull. Muscles may twitch. Participants may be asked to do simple movements during TMS. For sEMG, small electrodes will be attached to the skin and muscle activity will be recorded. At visit 2, participants will have magnetic resonance imaging (MRI). They will lie on a table that slides into a metal cylinder in a strong magnetic field. They will get earplugs for the loud noise. At visit 3, participants will have TMS, sEMG, and electroencephalography (EEG). For EEG, small electrodes on the scalp will record brainwaves. Participants will sit still, watch a movie, or do TMS. Participants may be asked to have 2 extra visits to redo procedures.
