- Registration Number
- NCT06214975
- Lead Sponsor
- Sheikh Shakhbout Medical City
- Brief Summary
The goal of this clinical trial is to demonstrate the improvement of motor functions related symptoms in patients with stroke and spasticity using Exopulse Mollii suit stimulation.
The main questions it aims to answer are:
to evaluate the short-term impact of EXOPULSE Mollii suit on balance in adult patients with stroke and suffering from spasticity.
to assess the effects of Exopulse Mollii suit on spasticity, mobility, pain, fatigue and QoL.
.
Participants will participate in:
One baseline visit for inclusion during which the patient will undergo the first session (active or sham) along with evaluations (before and after the session) One visit after two weeks during which the patient will undergo the second session (active or sham) along with evaluations (before and after the session) One visit after two weeks of the second stimulation condition; the patients will undergo a third evaluation and receive the EXOPULSE Mollii Suit for the four-week open label phase and will 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 fourth and last evaluation and return the EXOPULSE Mollii suit.
Researchers will compare both Active and Sham groups to demonstrate the improvement of motor functions related symptoms in patients with stroke and spasticity using Exopulse Mollii suit.
- Detailed Description
The study is a randomized crossover, sham-controlled, double-blind trial to demonstrate the improvement of motor functions and stroke related 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. Two weeks after the end of this phase (phase 1), a second phase of this trial, an open label phase, will be proposed for all patients to understand the effects of EXOPULSE Mollii suit employed over 4 weeks (a session every other day for a total of 14 sessions) on stroke related symptoms.

Group Intervention Description EXOPULSE Mollii Suit Stimulation Sham EXOPULSE Mollii Suit Stimulation 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. EXOPULSE Mollii Suit Stimulation Active EXOPULSE Mollii Suit Stimulation This will be the EXOPULSE Mollii Suit Active Stimulation. Stimulation will go on for 60 minutes while control unit is on for 60 minutes
- Primary Outcome Measures
Name Time Method Balance using Berg Balance Scale (BBS) To be assessed at week 8. Balance will be assessed using the 14-item Berg Balance Scale (BBS) which has good psychometric properties in patients with stroke (concurrent validity, interrater reliability). The scale rates the balance using 56 points, with higher scores indicating better balance abilities. A score equal to or below 45 is commonly associated with risk of fall across the literature.
- Secondary Outcome Measures
Name Time Method EQ-5D-5L: EuroQol 5 Dimensions 5 Levels Quality of Life Questionnaire Two weeks after the second stimulation and 4 weeks later at the end of phase 2. Muscle tone. This to be assessed at baseline, then at week 2, week 4 and week 8. 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.
Overall Clinical improvement This to be assessed at baseline, then at week 2, and week 8. 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.Fall Risk Two weeks after the second stimulation and 4 weeks later at the end of phase 2. 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.
Items are summed to a total score that will range from a minimum of 16 (no concern about falling) to a maximum of 64 (severe concern about falling).Weight Baseline. The patient weight will be measured and recorded in kilograms.
Visual Analog Score for spasticity. This to be assessed at baseline, then at week 2, week 4 and week 8. Spasticity will be measured using a visual analog score from 0 to 10, 0 being no spasticity and 10 being the worst possible spasticity.
Height Baseline The patient height will be measured and recorded in centimeters.
Body Mass Index (BMI) Baseline 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.
Visual Analog Score for pain. This to be assessed at baseline, then at week 2, week 4 and week 8. Pain will be measured using a visual analog score from 0 to 10, 0 being no pain, to 10 being the worst possible pain.
Blinding Questionnaire This to be assessed at baseline, then at week 2. 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.Visual Analog Score for fatigue This to be assessed at baseline, then at week 2, week 4 and week 8. Fatigue will be measured using a visual analog score from 0 to 10, 0 being no fatigue, to 10 being the worst possible fatigue.
Time Up and Go (TUG) This to be assessed at baseline, then at week 2, week 4 and week 8. Patients have to stand up from a chair when they hear the verbal instruction "go", walk a distance of 3 meters, turn around, walk back to the chair and sit down. Timing starts with the verbal instruction "go' and stops when the patients return to the seated position. The score consists of the time taken to complete the test activity, measured in seconds.
