Benign paroxysmal positional vertigo (BPPV) is the most common cause of peripheral vertigo. [2] It can be characterized by three main symptoms: positional onset, spinning dizziness and short-lived symptoms. The primary diagnostic maneuver is the Dix-Hallpike which elicits the cardinal sign associated with BPPV, rotatory nystagmus.
Feed left rudder as if to execute a stall turn. As the plane begins to stall, feed full right rudder, full right aileron, full down elevator, and full throttle. The aircraft should exhibit the Lomcevak while spiraling downwards. Exit the maneuver as the above method. This maneuver calls for a specific type of aircraft.
In aviation, in Australia, Canada, New Zealand, South Africa, the United Kingdom and elsewhere, HASELL or alternatively HASEL, is a standard mnemonic to prompt a series of checks prior to carrying out many types of manoeuvres, such as stalls, spins, spiral dives or aerobatics.
Because the methods of vestibular rehabilitation therapy differ for different disorders, the form of vestibular dysfunction, ability level, and history of symptoms, each patient must be carefully assessed in order to diagnose vestibular dysfunction and to choose the correct exercises for treatment.Vestibular physiotherapy entails precise maneuvers and sports designed to deal with inner ear ...
In modern aerobatics, this maneuver, if executed pre-stall with a non-zero turning radius at the top of the climb, is known as a wingover. If the rudder turn is executed right at the initiation of the stall, the resulting yaw occurs around a point within the aircraft's wingspan and the maneuver is known as a stall turn or hammerhead.
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.
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 aircraft begins at the dot, and pulls into a vertical climb. The small angled line at the top indicates a stall turn (without indicating the orientation after the turn). The plane then descends, pulls into horizontal flight, and ends at the small vertical line. The hammerhead turn, stall turn, or Fieseler is an aerobatics turn-around maneuver.
