About this study

Official title: EXO-MS: Effect of the EXOPULSE Suit on Mobility, Walking, and Balance in Multiple Sclerosis: A Double-Blind, Controlled, Parallel-Group Trial

This clinical research study is investigating whether the EXOPULSE Suit, a wearable device that delivers electrical stimulation, can help improve movement difficulties caused by spasticity in adults with multiple sclerosis (MS).

The main goal of the study is to evaluate the effect of the EXOPULSE Suit on functional mobility, with particular focus on walking ability and balance. The study will also assess the safety of the device by monitoring any adverse events that occur during the study.

Read more

Researchers will additionally evaluate the effects of the EXOPULSE Suit on:

  • Pain
  • Hand and finger dexterity
  • Fatigue
  • Quality of life

Participants will be randomly assigned to receive one of the stimulation programs being evaluated in the study. Some participants may receive a sham (placebo) stimulation. Neither the participants nor the study staff performing the assessments will know which stimulation program a participant has been assigned to during the study. This approach, known as blinding, helps ensure that the study results are as objective and reliable as possible.

Participants will use the EXOPULSE Suit for one hour every other day during a 4-week home-use period. Clinical assessments will be performed before and after the treatment period to evaluate changes in mobility and other symptoms.

It is important to note that individuals may experience the stimulation differently. Some participants may clearly feel the stimulation, while others may feel it only slightly or not at all. Not feeling the stimulation does not necessarily indicate which study group a participant has been assigned to, and a treatment effect may still be possible even when the stimulation is not perceived.

To ensure meaningful study results, participants are encouraged to use the EXOPULSE Suit as instructed throughout the study period, even if they do not notice a sensation of stimulation or an immediate improvement in their symptoms.

The study uses an adaptive design, meaning that an interim analysis will be performed during the study to determine the number of participants needed to reliably evaluate the study objectives.

Read the detailed description

The final sample size will be between 70 and 100, determined by the response rate and effect size, and will be defined after an IA was conducted once the first 50 participants have completed the study.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Electrostimulation suitDevice

    Also called EXOPULSE Suit

    One hour stimulation with an electrostimulation suit every other day. The EXOPULSE Suit provides low-intensity sensory electrical stimulation below the motor threshold. Unlike neuromuscular electrical stimulation (NMES), it is not intended to induce muscle contractions. The stimulation is conceptually similar to TENS but is delivered at lower intensities.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Balance responder rate: Percentage of patients achieving a clinically meaningful improvement in balance, as measured by the Berg Balance Scale (BBS), in the treatment group compared with sham-control group.

    Percentage of patients achieving a clinically meaningful improvement in balance, defined as a ≥6-point improvement from baseline 1 on the Berg Balance Scale (BBS) after 28 days (-3/+10 days) of treatment, compared with the corresponding proportion in the sham-control group.

    The Berg Balance Scale (BBS) is a 14-item clinical assessment designed to evaluate static and dynamic balance during functional tasks. Each item is scored on a 5-point ordinal scale ranging from 0 to 4, with a total score range of 0 to 56. Higher scores indicate better balance performance and lower fall risk, while lower scores indicate greater balance impairment. Points are deducted when a task cannot be completed independently, requires supervision or assistance, or does not meet the specified performance criteria. The BBS assesses balance during activities such as sitting, standing, transferring, reaching, turning, and single-leg stance.

    Measured: From Baseline 1 (start of treatment) to the post-treatment assessment after 28 days of treatment (-3/+10 days).

  2. Walking responder rate: Percentage of patients achieving a clinically meaningful improvement in walking ability, on the transformed 0-100 Multiple Sclerosis Walking Scale-12 (MSWS-12), in the treatment group compared with the sham -control group.

    Percentage of patients achieving a clinically meaningful improvement in walking ability, defined as a ≥8-point decrease from baseline 1 on the transformed 0-100 Multi-ple Sclerosis Walking Scale-12 (MSWS-12) after 28 days (-3/+10 days) of treatment, compared with the corresponding proportion in the sham-control group.

    The MSWS-12 is a self-report questionnaire designed to assess the impact of MS on an individual's walking ability. It consists of 12 items, each rated on a scale from 1 to 5, where 1 indicates no limitation, and 5 indicates extreme limitation. The items cover various aspects of walking, e.g.: ability to walk and run, climbing stairs, standing balance, walking distance and speed, effort required for walking. The total score is calculated by summing up the responses, which can then be transformed to a scale from 0 to 100, with higher scores indicating a greater impact on walking ability.

    Measured: From Baseline 1 (start of treatment) to the post-treatment assessment after 28 days of treatment (-3/+10 days).

Secondary outcomes (3)
  1. Walking endurance responder rate: Percentage of patients achieving a clinically meaningful improvement in walking endurance, as measured by the 6-Minute Walk Test (6MWT), in the treatment group compared with the sham-control group.

    Percentage of patients achieving a clinically meaningful improvement in walking endurance, defined as a ≥19.7-meter increase from baseline 1 on the 6-Minute Walk Test (6MWT) after 28 days (-3/+10 days) of treatment, compared with the corresponding proportion in the sham-control group.

    The 6-minute walk test is a sub-maximal exercise test used to assess aerobic capacity and endur-ance. The subject is asked to walk as far as possible for 6 minutes on a predefined track. The dis-tance covered over a time of 6 minutes is used as the outcome by which to compare changes in performance capacity.

    Measured: From Baseline 1 (start of treatment) to the post-treatment assessment after 28 days of treatment (-3/+10 days).

  2. MS impact responder rate: Percentage of patients achieving a clinically meaningful improvement in the impact of multiple sclerosis on daily life, as measured by the MSIS-29, in the treatment group compared with the sham-control group.

    Percentage of patients achieving a clinically meaningful improvement in the impact of multiple sclerosis on daily life, defined as a ≥9.1-point decrease from baseline 1 on the Physical subscale and a ≥5.5-point decrease from base-line 1 on the Psychological subscale of the Multiple Sclerosis Impact Scale-29 (MSIS-29) after 28 days (-3/+10 days) of treatment, compared with the corresponding proportion in the sham-control group.

    MSIS-29 is a self-report questionnaire designed to measure the impact of Multiple Sclerosis (MS) on a person's daily life. It consists of 29 items divided into two subscales: physical impact (20 items) and psychological impact (9 items). Each item is rated on a scale from 1 (not at all) to 5 (extremely), reflecting the extent to which MS affects various aspects of daily functioning. The scores for each subscale are summed and then transformed to a 0-100 scale, with higher scores indicating a greater impact of MS

    Measured: From Baseline 1 (start of treatment) to the post-treatment assessment after 28 days of treatment (-3/+10 days).

  3. Health-related quality-of-life responder rate: Percentage of patients achieving a clinically meaningful improvement in health-related quality of life, as measured by the EQ-5D-5L Utility Index, in the treatment group compared with the sham-control group.

    Percentage of patients achieving a clinically meaningful improve-ment in health-related quality of life, defined as an improvement from baseline 1 in the EQ-5D-5L Utility Index meeting or exceed-ing the subtype-specific minimal important change (MIC) thresh-old after 28 days (-3/+10 days) of treatment, compared with the corresponding proportion in the sham-control group.

    The EQ-5D-5L is a standardized measure of health-related quality of life consisting of five dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each dimension is rated on a 5-level scale ranging from no problems to extreme problems. Responses are combined into a health state that can be converted into a utility index score from less than 0 (worse than death) to 1 (perfect quality of live), with higher scores indicating better health-related quality of life.

    The EQ-5D-5L also includes a visual analogue scale (EQ VAS) ranging from 0 to 100, with higher scores better.

    Measured: From Baseline 1 (start of treatment) to the post-treatment assessment after 28 days of treatment (-3/+10 days).
