THE "DIX-HALLPIKE" MANUEVER / TEST ?
Every now and then, on various USMLE forums you come across a message asking about the Dix-Hallpike Test or maneuver ! Since the blog is dedicated to be a beacon of light for everyone thinking of , planning to or taking the CS, here goes ;-) :
This funny-sounding Test is a confirmatory diagnostic test for "Benign Paroxysmal Positional Vertigo", which accounts for probably about 1/5th cases of dizziness in the USA. So, this means, if you get a case of vertigo on the CS, or complaints like "Doctor I get dizzy", "The world goes round and round around me", etc. etc. .you should do this clinical test as a part of Physical Exam.
Beep : Dix-Hallpike test is also called the "Tilt Test" - you will soon see why ...
Yo Digitaldoc ! How do you do this test ?
Get the Standardized Patient (SP) to sit erect on his/her bed. Then, have the SP lie supine on the bed quickly , with the head turned (tilted) 45 degrees to one side and extended about 20 degrees backward. Once supine, the eyes are typically observed for about 30 seconds. If no nystagmus occurs, the person is brought back to sitting stance, only to test again with the head now turned to the opposite side.
On the exam , I don't expect anyone to get a positive test, simply because I don't imagine anyone with the condition actually volunteering to get Nystagmus 12 times a day ! But lets note that this test is considered "Positive" if the patient exhibits a burst of nystagmus when lying supine :-)
Dr. Timothy Cain does a much better job at explaining the test along with cool diagrams ! Click here.

God bless you
should we perform this test or can we simply write it as a part of the workup?
Should do it
There is a extremely useful article in the NEJM about benign paroxysmal positional vertigo, with a detailed explanation about the maneuvers and the anatomical basis of Dix-Hallpike test.
Here is the reference
Furman J, Cass S. Benign paroxysmal positional vertigo. NEJM 1999, 341:1590-6
