Fig. 2From: Dynamic walking features and improved walking performance in multiple sclerosis patients treated with fampridine (4-aminopyridine)Improvements in walking speed (a) and curve speed (b) associated with treatment onset of fampridine during test minute 1–4 (N = 35). The linear deceleration trend, consistently observable at Time 1 and Time 2, was most salient on the 25-foot distance (a; see Table 3 for statistics).
