Kurtzke Expanded Disability Status Scale (EDSS) mean scores. Possible scores range from 0 (no disability) to 10 (death resulting from MS complications). Scores from 1.0 to 4.5 indicate an ability to walk without any aid, and scores from 5.0 to 9.5 indicate an impairment to walking. N = 20 at 1 month (same as baseline), N = 17 at 1 year. Statistically significant changes between time points are indicated with their p-values. Error bars represent standard deviations
