The maneuver works by allowing free-floating particles, displaced otoconia, from the affected semicircular canal to be relocated by using gravity, back into the utricle, where they can no longer stimulate the cupula, therefore relieving the patient of bothersome vertigo. [2] [3] The maneuver was developed by the physician John M. Epley, and was ...

The head impulse test can be done at the bed side and used as a screening tool for problems with a person's vestibular system. [25] It can also be diagnostically tested by doing a video-head impulse test (VHIT). In this diagnostic test, a person wears highly sensitive goggles that detect rapid changes in eye movement.
The Brandt–Daroff exercises are performed in a similar fashion to the Semont maneuver; however, as the person rolls onto the unaffected side, the head is rotated toward the affected side. The exercise is typically performed 3 times a day with 5–10 repetitions each time, until symptoms of vertigo have resolved for at least 2 days.

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 horizontal by the clinician performing the maneuver. [3] The Dix–Hallpike and the side-lying testing position have yielded similar results.
Dizziness is a common medical complaint, affecting 20–30% of persons. [4] Dizziness is broken down into four main subtypes: vertigo (~25–50%), disequilibrium (less than ~15%), presyncope (less than ~15%), and nonspecific dizziness (~10%). [5] Vertigo is the sensation of spinning or having one's surroundings spin about them. Many people find ...
The Head-Up and Head-Down illusions are similar, involving sudden linear acceleration (Head-Up) or deceleration (Head-Down), leading to a misperception the nose of the aircraft is pitching up (Head-Up) or down (Head-Down); the aviator could be fooled into pitching the nose down (Head-Up) or up (Head-Down) in response, leading to a crash or a ...
