  7. Clinical Trial: Effect of Maximal Strength training on Gait and balance in persons with MS

    Subjects will undergo weight training using relatively high weights and low repetitions to determine the effect of this type of training on gait endurance, balance, and fatigue.
  8. Clinical Trial: Cognitive Rehabilitation Combined with Eye Movements

    This study is looking at how 12 weeks of computer-based cognitive rehabilitation may help improve memory and attention.  Key study eligibility requirements: Right handed adults diagnosed with RRMS. No relapses in the past 6 months. Noticeable decline in memory or other...
