Mar 4, 2020 · This guide provides a clear step-by-step approach to performing the head impulse, nystagmus and test of skew (HINTS) examination in an OSCE setting with an included checklist.

Aug 13, 2019 · Vertical skew (Test of Skew) Cover one eye for several seconds and then uncover that eye quickly. Central Finding: Realigning of the eye vertically is concerning. Caveat: This response may fatigue over serial exams during a short time period. HINTS in the ED

The HINTS exam is a cluster of three bedside clinical tests that aim to assess individuals presenting with acute-onset dizziness, vertigo, nystagmus, head motion intolerance, and nausea/vomiting, also known as acute vestibular syndrome (AVS).

A HINTS exam consistent with vertigo of central should have at least one of the follow-­‐ ing: a normal head impulse test (without a corrective saccade), nystagmus that changes direction on eccentric gaze, or a positive test of skew deviation (vertical ocular misalignment).

HINTS stands for Head Impulse, Nystagmus, and Test of Skew, and is a three-part oculomotor test. If any portion of the test indicates a central aetiology, the test is considered positive and further evaluation for stroke (or other central pathology) is warranted.

Jul 4, 2023 · Test of Skew Overview. Skew describes the vertical misalignment of the eyes due to vestibular dysfunction as a result of brainstem or cerebellar damage that is not due to oculomotor nerve or muscle problems. If a patient’s eye appears to be at a higher level than the other, there is skew deviation which can suggest a central cause of vertigo.

Skew deviation is a fairly specific predictor of brainstem involvement in patients with acute vestibular syndrome. The presence of skew may help identify stroke when a positive head impulse test falsely suggests a peripheral lesion. At least one stroke risk factor: Prior stroke or myocardial infarction.

The index test comprises three components: 1) head impulse test; 2) direction‐changing nystagmus; and 3) test of skew. A positive finding in any of the three components will be classified as a 'positive HINTS' examination for overall evaluation.

HINTS stands for Head Impulse, Nystagmus, and Test of Skew, and is a three-part oculomotor test. If any portion of the test indicates a central etiology, the test is considered positive and further evaluation for stroke (or other central pathology) is warranted.

Test of skew is evaluated by completing the cross-cover test (occluding one eye and then the other). If there is a vertical movement after the eye is uncovered, this is called a skew deviation and is a central localizing finding.
