  1. SS, simulator sickness; TENS, transcutaneous electric nerve stimulation.
  2. TN, E%, TN-E, CP are all parameters of the d2 test. TN, Total Number of item processed; E%, Percentage of Errors; TN-E, Total number of items minus error scores; CP, Concentration Performance. VAS-SS, Visual Analogue Scales for evaluating Sleepiness Symptoms.
  3. *p < 0.05 relative to control; #p < 0.05 relative to SS.
