When performing the Dix—Hallpike test, patients are lowered quickly to a supine position lying horizontally with the face and torso facing up with the neck extended 30 degrees below vertical by the clinician performing the maneuver.
Non-paroxysmal vertigo is more likely to be caused by a vestibular syndrome or central etiology, such as brain stem stroke. If the test is negative, it makes instrhctions positional vertigo a less likely diagnosis and central nervous system involvement should be considered. ibstructions
As such, the side-lying position can be used if the Dix—Hallpike cannot be performed easily. A Critically Appraised Topic”. Contraindications The Dix-Hallpike maneuver should be avoided in a patient with neck pathology, in whom the movements instruvtions could be dangerous to the patient.
Views Read Edit View history. Typically, after a five to second delay, this will cause vertigo and rotary or up-beating nystagmus, which will resolve within 60 seconds.
In these circumstances the side-lying test or other alternative tests may be used. Talmud 1 ; Scott C.
Each of the three canals is oriented slightly differently, with the anterior and posterior canals in the vertical plane, set to detect movement in the sagittal and coronal planes, respectively, and the lateral canal 30 degrees off from the horizontal plane, detecting movement to the left or right in the horizontal plane.
Such patients include those who are too anxious about eliciting the uncomfortable symptoms of vertigo, and those who may not have the range of motion necessary to comfortably be in a supine position.
The modification involves the patient moving from a seated position to side-lying without their head extending off the examination table, such as with Dix—Hallpike. The clinician then lies the patient down quickly with their head past the end of the bed and extends their neck 20 degrees below the horizontal, maintaining the initial rotation of the head.

Any neurological deficit, especially truncal ataxia, should generate concern for a central cause and trigger further workup. Review Maneuvers for the treatment of benign positional paroxysmal vertigo: Epub Apr The pathology, symptomatology and diagnosis of certain common disorders of the vestibular system.
