Walking workouts may sharpen the MS brain — a trial puts it to the test

NCT ID NCT05755061

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing This study
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This trial tests whether a 12-month aerobic walking program can improve cognitive processing speed and brain connectivity in adults with multiple sclerosis who have slowed thinking. Participants will be randomly assigned to one of two home-based walking programs that differ in intensity and frequency, with progress tracked via Fitbit. Researchers will measure changes in thinking speed, brain scans, and walking function at the start, middle, and end of the year.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Aerobic walking exercise programs (GEMS Plus and GEMS)
What this could lead to
If successful, this could establish a practical, home-based exercise prescription to help preserve or improve cognitive function and brain connectivity in people with MS.
What could go wrong
This is an early-phase trial with a small number of participants, so results may not apply broadly. The benefits of exercise on cognition may be modest, and adherence to a year-long program can be challenging.
