Table 1

Mean (SEM) values for the myotonic parameters and for small and large target displacements, as computed for the myotonic (MyD), multiple sclerosis (MS), and control groups

Myotonic parameterTarget displacementPatient groupMean(SEM)
The myotonic parameters were chosen for each given subject among those computed for each eye and for each saccade direction and separately for small and large amplitude paradigms. They correspond to the largest (as an absolute value) difference among the four available (two eyes and two saccade directions—namely, both directions for the large amplitude paradigms and centripetal directions alone for the small amplitude paradigms) between short and long ISI for corresponding parameters divided by the average of the two values. The differences were considered with their signs.
