Dizziness Due to Visual Stimuli in Patients with Concussion and Other Causes of Dizziness: Examination of Balance Behaviour

ClinConnect Summary

This clinical trial is studying how certain visual patterns can affect balance in people who experience dizziness, especially those who have had a concussion or other causes of dizziness. The researchers want to see how different types of visual stimulation, like moving patterns shown on a rotating disk or through a virtual reality headset, impact the balance of patients compared to healthy individuals. By observing how these visual effects make people feel—like if they experience dizziness, headaches, or nausea—the study hopes to better understand a condition called visually induced dizziness (VID) and improve how it is diagnosed and treated.

To participate in this study, you need to be between 18 and 60 years old and have had a recent concussion or dizziness symptoms. The researchers will only include those who have binocular vision (meaning you can use both eyes together) and have been experiencing symptoms within a specific time frame. Participants will undergo balance assessments while viewing the visual patterns, and they will be monitored for any symptoms they experience. This innovative approach aims to provide more accurate results that could help doctors better manage and treat patients with VID in the future.
