Abstract EN
Background.
The subjective visual vertical (SVV) is a perception often impaired in patients with neurologic disorders and is considered a sensitive tool to detect otolithic dysfunctions.
However, it remains unclear whether the semicircular canals (SCCs) are also involved in the visual vertical perception.
Objective.
The aim of this study was to analyze the influence of horizontal SCCs on SVV by caloric stimulation in healthy subjects.
Methods.
SVV was performed before and during the ice-cold caloric stimulation (4°C, right ear) in 30 healthy subjects.
Results.
The mean SVV tilts before and during the caloric stimulation were 0.31° ± 0.39 and −0.28° ± 0.40, respectively.
There was no significant difference between the mean SVV tilts before and during stimulation p = 0.113 .
Conclusion.
These results suggest that horizontal SCCs do not influence SVV.
Therefore, investigations and rehabilitation approaches for SVV misperceptions should be focused on otolithic and cognitive strategies.
