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.
