Multiple sclerosis (MS) is an autoimmune disease in which cells of the immune system attack the body itself. This condition generates an activation of the immune system that triggers an inflammatory response. General objective: To compare the effect of multifield FES and conventional FES on upper extremity motor skills and functional independence in people with MS. Methodology: A three-arm prospective longitudinal multicenter randomized controlled trial (RCT) will be conducted: conventional therapy (Control Group, CG), an experimental group 1 (EG1) which in addition to this same treatment will use the conventional FES tool, through the Globus Elite device, and an experimental group 2 (EG2) which will differ from GE1 in that it will use the FES multi-field device through FESIA Grasp. Results: It is expected that people who have used any type of FES will have a more normalized muscle tone compared to those who have not received this type of treatment. The research compares the effects of two types of FES in people with multiple sclerosis, focusing on improved motor skills and functional independence. Both FES treatments are expected to normalize muscle tone, showing superior results compared to those who do not receive this therapy.
