Abstract
Throughout the history of motion sickness research, it has been reported that the incidence of motion sickness is higher in females than males. Women rate themselves as more likely to suffer from motion sickness on all major forms of commercial transport and in different motion situations, such as carnival devices and gymnastics. Most of these studies employed survey questionnaires and self-reporting. This study investigates if there is a gender difference in induced sickness by comparing their physiological response and subjective symptoms rating under controlled laboratory conditions. Thirty healthy subjects (14 males and 16 females) between the ages of 18-46 years old were exposed to the Coriolis cross-coupling stimulation induced by 120°/s yaw rotation and a simultaneous 45° pitch forward head movement in the sagittal plane every 14 seconds. Cutaneous blood flow, blood pressure, heart rate, respiration, skin temperature, and electrogastrogram were monitored throughout the trial. Graybiel’s diagnostic criteria were used to assess sickness susceptibility before and after the Coriolis stimulation. Golding’s scale was used to assess the severity of symptoms during the motion exposure. A significant (p<0.01) increase of forearm and calf blood flow during cross-coupling stimulation was observed in both sexes. However, the subjective symptoms rating and objective cutaneous blood flow measurements indicated that there is no significant difference in sickness susceptibility
