Table 3.

There was greater between-session variability (variability measured as standard deviation, SD, across three trials) than within-session variability for nJerk ML EC and Sway Area EC, however more within-session variability for Trunk ROM yaw and Sway Range ML EC (Variability Type column). Student's t-test demonstrated significantly greater between-session variability for Sway Area EO and Sway Area EC in MSmod compared to controls and in MSmod compared to MS mild (Group column). Sway Area EC between-session variability was also significantly greater in MSmild compared to Controls (Group column).
