EXOPULSE Mollii Suit, Spasticity, Muscular Oxygenation & Multiple Sclerosis (ENNOX 2)

The Effects of EXOPULSE Mollii Suit on Spasticity and Muscular Oxygenation in Patients With Multiple Sclerosis.

The goal of this clinical trial is to demonstrate the improvement of muscular oxygenation in patients with Multiple Sclerosis and spasticity using Exopulse Molli suit stimulation. The main questions it aims to answer are: to evaluate the short-term impact of EXOPULSE Molli suit on muscular oxygenation in adult MS patients suffering from spasticity. to assess the effects of Exopulse Mollii suit on spasticity, pain, fatigue, quality of life (QoL), walking and risk of fall. Study subjects will participate in: One baseline visit for inclusion in the study during which the patient will undergo the first session (active or sham) along with an evaluation before and after the session One visit after two weeks during which the patient will undergo the second session (active or sham) along with an evaluation before and after the session One visit two weeks after the second stimulation; where the patients will undergo a fifth evaluation and receive the EXOPULSE Molli Suit for the four-week open label phase to use the suit at home for an active stimulation session every other day for four weeks. One visit at the end of the open label phase to perform the sixth and last evaluation and return the EXOPULSE Molli suit. Researchers will compare both Active and Sham groups to demonstrate the improvement of muscular oxygenation in patients with MS and spasticity using Exopulse Molli.

The study is a randomized crossover, sham-controlled, double-blind trial to demonstrate the improvement of tissue oxygenation and frequent MS symptoms following a single session of "active" versus "sham" Exopulse Mollii suit separated by 2 weeks. A 2-week washout period should be enough to prevent a potential carry over effect. After this phase (phase 1), a second open label phase (phase 2) will be proposed for patients to understand the effects of Exopulse Mollii suit employed for one month (3 sessions per week) on tissue oxygenation and MS related symptoms.

This will be the EXOPULSE Mollii Suit Active Stimulation. Stimulation will go on for 60 minutes while control unit is on for 60 minutes.

This will be the EXOPULSE Mollii Suit Sham Stimulation. Stimulation will go on for 1 minute then it turns off while the control unit will remain on for total of 60 minutes.

We designed a randomized crossover, sham-controlled, double-blind trial to demonstrate the improvement of tissue oxygenation and frequent MS symptoms following a single session of "active" versus "sham" Exopulse Mollii suit. A 2-week washout period should be enough to prevent a potential carry over effect. After this phase (phase 1), a second open label phase (phase 2) will be proposed for patients to understand the effects of Exopulse Mollii suit employed for one month (3 sessions per week) on tissue oxygenation and MS related symptoms.

Muscular Oxygenation will be assessed using the Near-infrared spectroscopy (NIRS) technology using a PortaMon device it will be employed to assess tissue oxygenation parameter (hemoglobin (tHb) in the territory of the spastic muscles before and after each session.

Muscular Oxygenation will be assessed using the Near-infrared spectroscopy (NIRS) technology using a PortaMon device it will be employed to assess tissue oxygenation parameter oxyhemoglobin (O2Hb) in the territory of the spastic muscles before and after each session.

Muscular Oxygenation will be assessed using the Near-infrared spectroscopy (NIRS) technology using a PortaMon device it will be employed to assess tissue oxygenation parameter deoxyhemoglobin (HHb) in the territory of the spastic muscles before and after each session.

Muscular Oxygenation will be assessed using the Near-infrared spectroscopy (NIRS) technology using a PortaMon device it will be employed to assess tissue oxygenation parameter tissue oxygenation index (TOI%)) in the territory of the spastic muscles before and after each session.

Spasticity will be evaluated using a Numerical Rating Scale (NRS) score from 0 to 10, 0 being no spasticity and 10 being the worst possible spasticity.

Quality of life will be measured using the 31-item Multiple Sclerosis International Quality of Life Questionnaire (MusiQoL) This questionnaire consists of 31 questions covering 9 domains including: 1- activity of daily living, 2- physical well-being, 3- relationships with friends, 4- symptoms, 5- relationships with family; 6- relationships with health care systems, 7- sentimental and sexual life, 8- coping; and 9- rejection. The questions are answered by ticking or checking the box that describes best of what patients would feel ranging from 0 to 4, 0 being not at all and 4 always or very much. For MusiQoL, the score of each of the nine sub domains is calculated as the average for the set of questions making up the domain. An overall score is then calculated as the average of all the scores for each subdomain. Prior to computing the final overall score, each domain-specific score is linearly transformed to a 0-100 scale with O being the worst quality of life and 100 the best.

Pain will be measured using a visual analog score from 0 to 10, 0 being no pain, to 10 being the worst possible pain.

Fatigue will be measured using a visual analog score from 0 to 10, 0 being no fatigue, to 10 being the worst possible fatigue.

Fall risk will be assessed using the Falls Efficacy Scale- International scale. It is a 16-item scale, including a range of functional activities, that assesses the perceived risk of falling, using a score that will range from 1 to 4, 1 being not at all concerned to 4 being very concerned.

Walking ability will be evaluated by the 12-item Multiple Sclerosis Walking Scale (MSWS-12). Each one of the 12 items will be assessed and assigned numbers from 1 to 5, 1 being not at all to 5 being extremely common, and the results will be added to a total of 60, so the higher the score, the better the mobility.

Evaluation of overall Clinical improvement will be done using the 7-point Clinical Global Impression (CGI). Patient will fill a questionnaire that will address their clinical situation as follows: Very much improved. Much improved. Slightly improved. No change. Slightly worse Much worse. Very much worse The score will range from 1-7, 1 being the best clinical outcome and 7 the worst.

Evaluation of patient's blinding to the type of stimulation in the crossover trial periods using a dedicated questionnaire. Patients will be asked whether they think they received the sham or active stimulation. No scale will be used for this measure.

Muscle tone will be evaluated by the Modified Ashworth Scale (MAS). Scores will range from 0 to 4, 0 being no increase or normal muscle tone, to 4 being rigidity in flexion or extension of muscles.

The weight and height will be combined to report BMI in kg/m^2. BMI of 35 kg/m^2 or more will be used as an exclusion criterion for the study.
