Design outcomes
Primary
| Measure | Time frame |
|---|---|
| In this study, post-rotatory nystagmus will be recorded for one minute following a rotational stimulation at 60degrees/sec under both conditions: with and without TENS application. From the obtained slow phase eye velocity (SPEV), the time required for the SPEV to decay to 37% of the maximal value (MaxSPEV) will be calculated as the time constant. Vestibular responses with and without TENS will be compared. Statistical analysis will be performed using the Wilcoxon signed-rank test to evaluate differences between conditions. | — |
Secondary
| Measure | Time frame |
|---|---|
| The Motion Sickness Assessment Questionnaire (MSAQ) scores will be compared between the TENS and non-TENS conditions to evaluate subjective changes in motion sickness symptoms induced by TENS. | — |
