Training to Improve Arm Movement Using Visual Feedback in Adults with Cerebellar Ataxia

What this Trial Is About

Researchers are evaluating the benefits of a reinforcement-based training program versus standard practice over several weeks to improve reaching movements in adults with cerebellar ataxia. This condition, caused by damage to the cerebellum from stroke, tumor, or degeneration, results in impaired coordination affecting daily activities like eating and dressing. The study aims to assess whether longer-term training can better reduce arm ataxia compared to previous short-term studies. Participants will be randomly assigned to two groups to receive either reinforcement training or standard practice training using an Oculus Rift and Touch 3D headset. Training involves reaching to four virtual targets 400 times per session, with sessions lasting 45 minutes, three times a week for two weeks, followed by a two-week rest before switching to the other training type. Motion sensors will track limb movements in real time during these sessions. Throughout the 12-week study, participants will attend regular visits where researchers will measure hand path distance during reaching tasks to assess improvement. Additional assessments include the International Cooperative Ataxia Rating Scale and the Action Research Arm Test at the start and end of the training. The study will help understand long-term effects of visual feedback training on arm movement in cerebellar ataxia.
