Participation Criteria
Eligibility Criteria
Ages Eligible for Study
Accepts Healthy Volunteers
Description
All participants will:
- Be between the ages of 18-65
- Have a clinically definite MS diagnosis based on established criteria
- Be fully-ambulatory based on Expanded Disability Status Scale (EDSS) scores between 0-4.0
- Demonstrate slowed CPS based on initial SDMT scores at least 1 SD below the regression-based normative score for healthy controls (i.e., 16th percentile)
- Be relapse-free and will not have acutely taken corticosteroids for at least 30 days (i.e., relative neurologic stability)
- Not have a history of major depressive disorder, schizophrenia, bipolar disorder I or II, or substance-abuse disorders.
- Not be taking medications that can affect cognition (e.g., antipsychotics, benzodiazepines).
- Be right-handed
- Have corrected vision better than 20/80
- Not have known/diagnosed cardiovascular, metabolic, or renal disease. Individuals with known/diagnosed cardiovascular, metabolic, or renal disease who are asymptomatic will be included only with a physician's approval.
- Demonstrate scores on the Mini-Mental State Examination (MMSE) of 21 or higher (no decisional impairment)
- Be on a stable disease-modifying therapy regimen (i.e., at least 6 months prior to study enrollment).
- Have a low risk for contraindications for MRI based on not having metal (e.g., non-MRI compatible aneurysm clips, metal shards in the body or eyes, or recently placed surgical hardware) or electronic devices (e.g., pacemaker, cochlear implant) within the body.
- Not be pregnant
- Not be engaging in ≥ 150 min of moderate-to-vigorous physical activity (i.e., not meeting public health guidelines for physical activity) per week
- Not be actively engaging in cognitive rehabilitation, or participating in regular brain fitness activities
- Demonstrate systolic blood pressure values of < 200 mmHg or diastolic blood pressure values < 110 mmHg at rest

Experimental: Treadmill Walking Exercise Training
This condition will include 3-months of supervised, progressive light, moderate, and vigorous intensity treadmill walking exercise training based on ACSM guidelines for maximizing adaptations with exercise training. Exercise intensities will be prescribed based on percent oxygen consumption reserve (% VO2R) using values derived from the baseline graded exercise test. The exercise training itself will be led by trained exercise leaders who are not involved in the collection of outcome assessments. At the outset of each session, participants will be fitted with a Polar HR Monitor (Oy, Finland), and HR will be monitored continuously throughout each session. Each session will begin with a 5-10 min warm-up, followed by the exercise; the target heart rate reserve (HRR) range associated with the VO2R range will be maintained for as long as possible during each exercise period. This will be followed by a 5-10 min cool-down. |
12-weeks of supervised, progressive treadmill walking exercise training
|
Active Comparator: Stretching-and-Toning Exercise Training
The active, non-aerobic exercise condition will involve stretching-and-toning activities using the same frequency and duration of the treadmill walking exercise condition.
These activities will be based on a manual provided by the National Multiple Sclerosis Society and sessions will be led by trained exercise leaders who are not involved in the collection of outcome assessments.
Activities will target the head/neck, shoulder, elbow/forearm, hand/wrist, trunk/hip, ankle/foot.
The progression of activities over the 3-month period will involve performing additional exercises and sets along with using progressively thicker elastic resistance bands that provide minimal resistance.
Each session is designed to last up to 60 minutes in total.
Each session will begin with a warm-up of up to 10 minutes, followed by stretching-and-toning (following the same duration as the treadmill walking exercise training condition) activities, and a cool-down of up to 10 minutes.
