What is the purpose of this trial?

This trial aims to determine how combining brain exercises with physical activity can help people with multiple sclerosis (MS) improve their learning and memory skills. Participants will try different combinations, such as aerobic exercise with virtual reality (Aerobic Exercise Training plus Virtual Reality, IDEAL) or stretching and toning, along with a memory-boosting program. It targets individuals with MS who experience mobility issues and do not currently exercise regularly. As an unphased trial, this study provides a unique opportunity to explore innovative methods to enhance cognitive and physical health for those with MS.

Will I have to stop taking my current medications?

If you are currently using medications that may affect thinking, like steroids or benzodiazepines, you will need to stop taking them to participate in this trial.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that combining aerobic exercise with virtual reality is safe for people with multiple sclerosis (MS). Studies indicate that this method does not increase the risk of negative side effects, and participants generally handle it well, with no significant rise in unwanted effects.

Stretching and toning exercises are also considered safe for individuals with MS. Several studies confirm that these exercises do not raise the risk of relapses or serious side effects. Exercise is often recommended to improve overall health in people with MS.

The Kessler Foundation modified Story Memory Technique (KF-mSMT®), which involves mental exercises to boost memory, has been tested and found to be safe. Research supports its use without significant risk, and participants usually manage it well, with no reported safety issues.

In summary, these treatments—exercise, virtual reality, and memory techniques—are safe options for those with MS. They are well-tolerated and do not lead to significant negative effects. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about these treatments for multiple sclerosis because they combine cognitive rehabilitation with innovative exercise methods to potentially enhance memory and cognitive function. The first approach integrates aerobic exercise with virtual reality, making workouts more engaging and potentially more effective in improving memory, thanks to the IDEAL system. The second approach combines cognitive rehabilitation with stretching and toning exercises, offering a gentler physical activity option while still incorporating the Kessler Foundation modified Story Memory Technique® to boost memory. Both methods aim to go beyond standard exercise or cognitive therapies by integrating these unique elements, potentially leading to better outcomes for patients.

What evidence suggests that this trial's treatments could be effective for multiple sclerosis?

This trial compares two approaches for cognitive rehabilitation in people with multiple sclerosis (MS). One treatment arm combines aerobic exercise with virtual reality. Studies have shown that this combination can improve memory and learning in people with MS by enhancing brain function and memory skills. Research indicates that this approach can address cognitive issues related to MS.

The other treatment arm involves stretching and toning exercises. Evidence suggests these exercises improve flexibility and muscle strength in people with MS. While stretching alone may not significantly reduce muscle tightness, it contributes to overall physical health. In this trial, combining stretching with memory exercises, such as the Kessler Foundation's technique, is expected to improve memory outcomes. ^{1 2 4 5 6}

• Stretching and Toning (S/T)
• The Kessler Foundation modified Story Memory Technique® (KF-mSMT®)

Trial Overview

The study tests if combining cognitive rehabilitation (using Kessler Foundation's modified Story Memory Technique) with physical exercises (stretching/toning and aerobic training enhanced by virtual reality) can improve new learning and memory in people with Multiple Sclerosis who also have mobility disabilities.

How Is the Trial Designed?

Group I: Cognitive Rehabilitation + Stretching and Toning Experimental Treatment 2 Interventions

In the cognitive rehabilitation and stretching and toning (S/T) exercise condition, participants will complete 12 weeks of supervised S/T activities 3 days per week over the 12 week period. For seven weeks, participants will only complete S/T. During weeks 8-12, participants will complete the Kessler Foundation modified story Memory Technique (KF-mSMT®), a memory retraining program on 2 of the 3 days per week.

Group II: Cognitive Rehabilitation + Aerobic Exercise with Virtual Reality (VR) Experimental Treatment 2 Interventions

In the cognitive rehabilitation and aerobic exercise with VR condition, participants will complete a supervised, aerobic exercise training program (AET) integrated with virtual reality (Ideally Designed Exercise to Accelerate Learning/memory; IDEAL) three days per week over a 12 week period. For seven weeks, participants will only complete IDEAL. For weeks 8-12, participants will complete the Kessler Foundation modified story Memory Technique (KF-mSMT®), a memory retraining program on 2 of the 3 days per week.

Inpatient rehabilitation for multiple sclerosis (MS) can improve functional independence but has limited long-term success in reducing neurological impairment, with severely disabled individuals benefiting as much as or more than those with less disability.

Exercise, particularly aerobic activities that include balance training and social interaction, has been shown to enhance fitness and maintain function in individuals with mild to moderate MS, suggesting that rehabilitation should be an ongoing process tailored to individual needs.

In a study involving 62 participants with moderate-to-severe traumatic brain injury (TBI), the Kessler Foundation modified Story Memory Technique® (KF-mSMT®) did not show a significant treatment effect on learning slopes compared to a placebo, indicating that processing speed (PS) may not directly influence learning outcomes.

However, processing speed was found to be a significant predictor of post-treatment changes following KF-mSMT®, suggesting that cognitive dysfunctions beyond learning and memory can affect the overall benefits of cognitive rehabilitation for TBI patients.
