EXOPULSE Suit to improve walking in people with multiple sclerosis

Walking Ability of Patients With Multiple Sclerosis Using the EXOPULSE Suit: Randomized Controlled Crossover Trial

NA · Otto Bock France SNC · NCT07252895

This will try the EXOPULSE Suit, a wearable that delivers multisite electrical stimulation, to see if it helps people with multiple sclerosis walk better.

What this trial studies

The EXOPULSE Suit is a non-invasive wearable garment with 50 electrodes that can stimulate up to 43 major muscle groups to reduce spasticity and support balance. In this interventional study, people with MS and moderate disability (EDSS 4–6) will use the suit at home for one hour every other day and outcomes will focus on walking ability. Participants will use the suit in active or sham modes so the effects of the electrical stimulation can be compared. The trial is being run at three French centers and targets people who cannot or prefer not to use fampridine.

Who should consider this trial

Good fit: Ideal candidates are adults with a confirmed MS diagnosis, EDSS between 4 and 6, measurable lower-limb spasticity, stable walking for at least two weeks, who have not previously used the EXOPULSE Suit and who cannot take or do not tolerate fampridine.

Not a fit: People with implanted electronic devices (e.g., pacemakers), contraindications to the suit, severe disability outside the EDSS 4–6 range, no measurable lower-limb spasticity, or under 18 years old are unlikely to benefit or be eligible.

Why it matters

Potential benefit: If successful, the suit could offer a non-drug option to reduce spasticity and improve walking speed, balance, and daily mobility for people with MS.

How similar studies have performed: Multisite electrical stimulation and other wearable neuromodulation approaches have shown preliminary mobility benefits in MS, but the EXOPULSE Suit itself is relatively new and needs confirmatory trials.
