Vibro-motor Reprocessing Therapy towards Managing Motion Sickness Reduction: Evidence from EEG

Area of Science:

• Neuroscience
• Medical Engineering

Background:

• Motion sickness is a common condition affecting many individuals.
• Current treatments often involve pharmacological interventions with potential side effects.
• Vibro-motor reprocessing therapy (VRT) is a novel technique adapted from EMDR.

Purpose of the Study:

• To evaluate the efficacy of VRT in reducing visually induced motion sickness.
• To investigate the neural correlates of VRT's effect on motion sickness using EEG.
• To explore VRT as a potential non-pharmacological treatment for motion sickness.

Main Methods:

• Eight participants experiencing visually induced motion sickness were exposed to VRT and non-VRT conditions.
• Electroencephalography (EEG) was used to record brain activity at baseline and during stimulation.
• Comparisons of spectral power in alpha, delta, and theta frequency bands were made between conditions.

Main Results:

• A significant reduction in alpha (8-12 Hz) spectral power was observed in frontal and occipital regions during VRT.
• Significant reductions in frontal and occipital delta (0.5-4 Hz) and theta (4-8 Hz) spectral power were found in the VRT condition compared to non-VRT.
• These EEG changes correlated with reduced motion sickness symptoms.

Conclusions:

• VRT demonstrates efficacy in attenuating motion sickness, evidenced by changes in neural activity.
• The study suggests VRT as a viable non-pharmacological alternative to drug-based treatments.
• Real-time monitoring and alleviation of motion sickness symptoms are possible with VRT and EEG.
