Aim 1. This study will objectively evaluate the clinical utility of a memory retraining protocol to improve performance on objective tests of new learning and memory in a large sample of individuals with MS with documented deficits in this area. This protocol has been previously utilized in a traumatic brain injury (TBI) population and a small pilot sample of individuals with MS, yielding promising data. NCMRR states that research analyzing existing rehabilitation techniques, empirically assessing their validity, and providing justification to the consumer and practitioners is required for the advancement of the field of medical rehabilitation research and recognizes this as a high priority research area. Our study does precisely this.
