Take your finger out past 18-24” to examine if the patient has full ocular range of motion. Ask the patient to follow moving target that is held several feet in front of the patient’s face (to avoid convergence of …

Jeff Walter, PT, DPT, NCS demonstrates how to perform a test for VOR Cancellation during a bedside vestibular exam.

It delivers sensory input about head velocity, and that aids the VOR to generate an eye movement which is equivalent to the velocity of the head movement.

This test causes stimulation of both the canals at once, which provides information about the function of the vestibular system as a whole during head rotation.

Purpose: The VOR-Cx test assesses the ability of the smooth pursuit system to override the VOR during combined eye and head tracking. This is a complex polysynaptic reflex that is managed by neural …

Jun 2, 2021 · 3: Vestibulo-ocular Cancellation (VORcX): this is a test for visual motion sensitivity via the cerebellum’s ability to inhibit the Vestibulo-ocular reflex. Standing, clasp your hands in front of …

The VOR cancellation test, also referred to as the vestibulo-ocular reflex (VOR) suppression test, is a diagnostic procedure used to assess the patient's ability to suppress the VOR during rotational …

The VOR cancellation test interrogates the circuit that controls visually-mediated override of the VOR during combined eye-head tracking. This is a complex (and incompletely defined) polysynaptic reflex …

VOR CANCELLATION Step 1: Sit in supportive chair with object to focus on (finger, pen, or paper with X on front). Step 2: While maintaining your focus on the object, turn your head and object in the …

Recent advances in digital health technology, such as smartphone-based videooculography, offer a promising alternative for assessing VORS in a more accessible, efficient, and quantitative manner.
