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 …

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

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.

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.

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 …

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 …

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) …

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 …

Visual Motion Sensitivity (VMS) Test – Test visual motion sensitivity and the ability to inhibit vestibular-induced eye movements using vision. The patient stands with feet shoulder width …

Since smooth pursuit cancels the VOR, visual cancellation of the VOR is an important test for the pursuit system. Prior to testing the visual cancellation of the VOR, the examiner should ensure …
