Materials & Methods: A serial reaction time task by using software was applied for studying explicit motor learning in 15 RRMS patients and 15 matched healthy subjects. In this task four squares with different colors appeared on the computer screen and the subjects were asked to press 1 of 4 keys corresponding to the appropriately colored square immediately after observing it. In the first day subjects practiced 8 motor blocks with a retention test consisted of 2 patterned blocks, 48 hours later. Before test, the subjects were told the order of random and patterned blocks, and then RT values were calculated for each block and K-S test, paired T test and independent-samples t-test were used to analyse the measured blocks times. Results: The patient groups performed this task slower than healthy groups (P M3 ER -
