  1. MS multiple sclerosis, EP evoked potentials, UL upper limb, LL lower limb, MEP motor evoked potentials, SEP somatosensory evoked potentials, VEP visual evoked potentials, EDSS expanded disability status scale, mFS pyramidal functional system, sFS sensory functional system, vFS visual functional system, Max maximal theoretical value for each individual score (i.e. 30 for Global EP score, 10 for individual EP score and EDSS, 6 for functional system)
