Details and patient eligibility
About
This is a randomized, double-blind pilot clinical trial to test a novel treatment approach to rehabilitate fine motor function in individuals living with progressive multiple sclerosis (MS) using anodal transcranial direct current stimulation (tDCS) to augment manual dexterity training. Treatment will be delivered to individuals at home using a state-of-the-art remotely supervised tele-rehabilitation protocol, a major advantage for patients with respect to ease of access, feasibility, reinforcement learning and minimal burden of in clinic study visit participation. Improvements in fine motor skill will be assessed at each remote session using a novel portable grip device that measures execution and adaptation or learning of fingertip forces during grasp, which is more sensitive than standard measures of hand function.
