The video ocular counter roll (vOCR) test effectively evaluates otolith function by measuring the torsional vestibulo-ocular reflex. This bedside test aids in identifying vestibular loss stages and recovery progress.
Area of Science:
- Neurology
- Ophthalmology
- Vestibular Science
Background:
- Vestibular otolith function is crucial for balance and spatial orientation.
- Assessing otolith function traditionally requires complex or time-consuming tests.
- A need exists for a simple, bedside test to evaluate otolith pathways.
Conclusions:
- The vOCR test is a valuable clinical tool for evaluating vestibular otolith function.
- Its simplicity and speed allow for bedside assessment.
- vOCR aids in diagnosing and monitoring vestibular dysfunction and recovery.
