A significant main effect was found only for LSOT condition. No interaction effect was present. Post-hoc analysis using pairwise Tukey comparisons revealed significant differences between conditions LSOT 1 and LSOT 5.

LSOT: Locomotor Sensory Organization Test; MV: Mastoid Vibration.

^!Significant difference exhibited when compared to LSOT condition 1.

^#Significant difference exhibited when compared to LSOT condition 5.
