We recognize that performing cervical manipulations can be scary as a clinician. To help you in your assessment, here is a free video from our Insider Access Page on how to assess the cervical spine mobility. Enjoy!

Vertebral Artery Test

Purpose: To assess the contributions of vertebral artery occlusion to the patient’s symptoms.

Test Position: Sitting.

Performing the Test: Patient rotates head opposite to tested side maximally and holds position for 10 seconds. Patient returns to neutral for 10 seconds. Patient extends head for 10 seconds. Patient returns to neutral for 10 seconds. Patient extends and rotates head (again opposite tested side) maximally for 10 seconds. Positive symptoms include (The 5 D’s) dizziness, diplopia, dysarthria, dysphagia, drop attacks, nausea and vomiting, sensory changes, nystagmus, etc.

Diagnostic Accuracy: Sensitivity: 0%; Specificity: .67-90%; +LR: .21-.87; -LR: 1.02-1.40 (“Cote P et al. J Manipulative Physiol Ther. 1996”).

Importance of Test: If a patient tests positive on the Vertebral Artery test, they may have Vertebrobasilar Insufficiency (VBI), but if they test negative on it, you CANNOT rule out Vertebrobasilar Insufficiency. The theory behind this test is to maximally stress the opposite vertebral artery by stretching it to decrease the space in the lumen of the artery. The position of extension with contralateral rotation has been shown to decrease the diameter of the artery, but, again, the diagnostic accuracy of the test is still poor.

Note: tests should only be performed by a properly trained health care practitioner.
