Delivery of a Culturally Tailored Exercise Training Intervention for Hispanics With Multiple Sclerosis
(VAMOS-MS)
What this study is about
The purpose of this study is to establish differences in the primary outcome of walking dysfunction using the 12-Item Multiple Sclerosis Walking Scale (MSWS-12) and to establish differences in the secondary outcome of HRQoL using the 29-Item Multiple Sclerosis Walking Scale (MSWS-29) between the exercise training intervention condition and the waitlist control condition following the 16-week intervention period.

The purpose of this study is to establish differences in the primary outcome of walking dysfunction using the 12-Item Multiple Sclerosis Walking Scale (MSWS-12) and to establish differences in the secondary outcome of HRQoL using the 29-Item Multiple Sclerosis Walking Scale (MSWS-29) between the exercise training intervention condition and the waitlist control condition following the 16-week intervention period.
Interventions
BEHAVIORAL
Exercise Training
Participants will then be mailed exercise materials in their preferred language, including the program manual, logbook, calendar, newsletters, Fitbit, and resistance bands, along with instructions for telephone or video conference calls. This is a 16-week, home-based program, supported remotely via Internet-based behavioral coaching, which integrates behavior change techniques based on Social Cognitive Theory (SCT)
Primary outcome measures
Change in walking ability as assessed by the 12-Item Multiple Sclerosis Walking Scale (MSWS-12)
Time frame: Baseline, 16 weeks, 32 weeks
This is a 12 item questionnaire and each is scored on a 5-point Likert scale from 1(not at all) to 5(extremely). Total raw scores ranging from 12-60 are converted into standardized scores from 0-100, with higher scores indicating greater perceived walking impairment related to multiple sclerosis.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- diagnosis of MS
- relapse-free in the past 30 days
- self-identify as Hispanic/Latino
- Patient Determined Disease Steps Scale (PDDS) score between 3.0 (gait disability) and 6.0 (bilateral support) indicates walking disability.
- MSWS-12 score between 25 and 75, indicating walking disability
- Willingness to complete the questionnaires and undergo randomization
- English or Spanish as a primary language
Exclusion criteria
- significant exercise-related risk factors or contraindications, assessed individually using the Physical Activity Readiness Questionnaire (PAR-Q; requires clearance from physician).

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
