The Epley maneuver [31] employs gravity to move the calcium crystal build-up from the posterior semicircular canal (resulting in diagonal nystagmus) that causes the condition. [35] This maneuver can be performed during a clinic visit by health professionals, or taught to people to perform at home, or both. [36]
Epley maneuver. The Epley maneuver or repositioning maneuver is a maneuver used by medical professionals to treat one common cause of vertigo, benign paroxysmal positional vertigo (BPPV) [1] [needs update] of the posterior or anterior canals of the ear. [2]
For some patients, this maneuver may be contraindicated, and a modification may be needed that also targets the posterior semicircular canal. 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 brain can then decide which muscles in the body need to become active in order to right itself. The semicircular canals have a superior, posterior, and horizontal component. Studies have shown that the horizontal canal is most correlated with agility, as shown with several mammals. [3]
The posterior surfaces of the duodenum and pancreas become visible, allowing for the examination of the hidden peripheral parts of the common bile duct. [ 2 ] Portal Exposure: The manoeuvre exposes the porta hepatis, allows dissection of the hepatoduodenal ligament, and provides access to the lesser sac by opening the foramen of Winslow.
A positive Pemberton's sign is indicative of superior vena cava syndrome (SVC), commonly the result of a mass in the mediastinum.Although the sign is most commonly described in patients with substernal goiters where the goiter "corks off" the thoracic inlet, [4] the maneuver is potentially useful in any patient with adenopathy, tumor, or fibrosis involving the mediastinum.

Diver clearing ears Section of the human ear, the Eustachian tube is shown in colour. Ear clearing, clearing the ears or equalization is any of various maneuvers to equalize the pressure in the middle ear with the outside pressure, by letting air enter along the Eustachian tubes, as this does not always happen automatically when the pressure in the middle ear is lower than the outside pressure.
