Resting state functional connectivity (fcMRI) between left and right primary motor cortices in MS patients on Fingolimod treatment was studied at baseline (just before the start of the treatment), 6 months and 12 months after start of treatment. Since such fcMRI metric has been previously reported to be reduced, changes in fcMRI over every 6 months interval were correlated with changes in clinical score as measured by 9 hole peg test duing the treatment course. A significant difference in the correlation was observed between dominant and non-dominant hand performance in between 6 and 12 months.
