 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 head is rotated 45 degrees away from the side being tested, and the eyes are examined for nystagmus.
