a Data for normally distributed variables are presented as mean (SD), and those for nonnormal variables are presented as median (interquartile range [IQR]). For consistency, data for all Sensory Organization Test (SOT) conditions are presented as median (IQR) because of bimodal distributions (ie, falls) in the more difficult conditions. 6MWT = 6-Minute Walk Test; ABC = Activities-Specific Balance Confidence Scale; FGA = Functional Gait Assessment; FSS = Fatigue Severity Scale; MFIS = Modified Fatigue Impact Scale; MS = multiple sclerosis; SVV = subjective visual vertical; VOR = vestibular ocular reflex.
