Individuals susceptible to seasickness rely more on visual and somatosensory input for balance. This suggests altered sensory weighting contributes to motion sickness and impaired spatial orientation.

Area of Science:

  • Neuroscience
  • Human Physiology
  • Sensory Integration

Background:

  • The neural mismatch theory posits that conflicting sensory inputs cause motion sickness and adaptation.
  • Individual differences in motion sickness susceptibility may stem from variations in how sensory information is integrated.
  • Computerized dynamic posturography (CDP) allows for controlled manipulation of visual, somatosensory, and vestibular inputs to assess balance.

Purpose of the Study:

  • To investigate balance control strategies in naval crew members with varying susceptibility to seasickness.
  • To determine if differences in sensory weighting during balance tasks correlate with seasickness proneness.

Main Methods:

  • A cross-sectional, parallel-group study design was employed.
  • Twenty seasickness-susceptible (SS) and 20 non-susceptible (NSS) healthy male volunteers (ages 18-25) participated.

  • The EquiTest system was used to perform the Sensory Organization Test (SOT).

    • Main Results:

    • The SS group demonstrated significantly reduced postural stability compared to the NSS group, particularly in SOT condition 5.
    • The ratio of SOT scores between condition 5 and condition 1, reflecting vestibular-somatosensory integration, was significantly lower in the SS group.
    • These findings indicate a potential difference in sensory reliance for balance maintenance between susceptible and non-susceptible individuals.

    Conclusions:

    • Seasickness susceptibility may be associated with a greater reliance on somatosensory and visual inputs and a lesser reliance on vestibular inputs for balance.
    • Abnormal weighting of sensory modalities during multisensory integration could underlie increased susceptibility to motion sickness.
    • Disrupted sensory integration may impair balance and spatial orientation in environments with conflicting sensory information.
