Comparison between Motor Performance of People with Multiple Sclerosis during a Virtual Reality Task Practiced on Concrete and Abstract Devices: A Cross-Sectional Randomized Study.

Multiple sclerosis (MS) is an autoimmune demyelinating disease of the central nervous system with unknown etiology, resulting in various impairments that necessitate continuous rehabilitation to enhance functionality, quality of life, and motor function, including through Virtual Reality (VR) therapy. Comparing tasks in virtual environments and their potential skill transfer to real-world settings could aid in optimizing treatment programs to improve motor performance in individuals with MS. This study aimed to determine whether practicing acquisition and retention phases using two distinct interfaces (concrete-Touch Screen or abstract-Kinect system) affects performance in a subsequent task using a different interface (transfer phase).
