Motion Sickness Rehabilitation for Virtual Reality
Condition: Motion Sickness
MeSH terms: Motion Sickness
Study type: Interventional

Summary: 
      The objective of this study was to investigate the effect of a rehabilitation program on
      motion sickness. A combined rehabilitation program will be given participants who showed
      motion sickness symptoms.
    

Detailed description: 
      In the realm of virtual environments and simulators, a significant hurdle that hampers user
      engagement resides in the manifestation of adverse effects. These deleterious consequences
      become apparent during prolonged exposure to virtual settings, with approximately 30% of
      users grappling with symptoms like nausea and up to 40% reporting eyestrain. Furthermore,
      users frequently describe a constellation of other discomforting sensations, including
      headaches, dizziness or vertigo, compromised postural stability, drowsiness, increased
      salivation, and perspiration. These adverse effects have been documented in scientific
      literature under various monikers, with 'cybersickness' and 'motion sickness' (MS) being the
      most prevalent designations.

      Motion sickness, a vexing symptom characterized by discomfort experienced during movements
      unrelated to one's bodily motions, such as those encountered during travel by air, sea, or
      land, lies at the crux of this issue. The pathophysiological elucidation of the mechanisms
      underlying MS centers around the notion of sensory conflict or sensory mismatch. This
      conflict arises from disparities between the sensory information derived from kinaesthetic
      inputs, the vestibular and visual systems, and the sensory patterns engendered by the virtual
      environment
    

Intervention name(s): Combined Exercises; Placebo Exercise
Intervention type(s): Other; Other
Intervention description(s): The treatment involving multisensory stimulation through active movement was structured into two distinct segments. The initial segment encompassed exercises executed on a wobble board, comprising tasks such as squats, passing a ball between hands and to another individual, maintaining a single-leg stance, and gently destabilizing each other's balance. The subsequent segment involved exercises performed on a soft mat, including activities such as jumping from a small box and landing with both knees flexed, passing the ball to a team member during a two-leg jump, executing a two-leg jump while rotating the trunk by 90 degrees, and leaping from a small box onto a soft mat while balancing on one leg. Each of these exercises was repeated ten times within each session.
Balance-related exercises were conducted with participants assuming a shoulder-width stance on both firm and soft surfaces.; Participants allocated to the control group will receive placebo treatment sessions, which entailed a 10-minute exposure to a visual evoked potential (VEP) measurement screen while holding a mouse. During this time, participants were given instructions to click the mouse whenever the screen exhibited a change in color. These activities were carried out while seated in a chair equipped with arm support
