[2] [3] After that the patient is carefully rolled in the desired direction without twisting or bending the body. Log-rolling. Typically logrolling into a supine position is used for transport of a casualty. Other cases include logrolling on a side, e.g., to facilitate vomiting., [3] or from side to side, for medical examination. [4]
The Dix–Hallpike [1] or Nylén–Bárány [2] test is a diagnostic maneuver from the group of rotation tests used to identify benign paroxysmal positional vertigo (BPPV). Procedure [ edit ]
Each episode of vertigo typically lasts less than one minute. [3] Nausea is commonly associated. [7] BPPV is one of the most common causes of vertigo. [1] [2] [8] BPPV is a type of balance disorder along with labyrinthitis and Ménière's disease. [3] It can result from a head injury or simply occur among those who are older. [3]
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 ...
Videonystagmography (VNG) is a type of testing used to assess vestibular and central nervous system function through the use of eye movement tracking, specifically evaluating nystagmus. [1]
Log rolling, sometimes called birling, is a Sparring Sport involving two competitors, each on one end of a free-floating log in a body of water. The athletes battle to stay on the log by sprinting, kicking the log, and using a variety of techniques as they attempt to cause the opponent to fall off.
Benign paroxysmal positional vertigo, or BPPV, is a disorder caused by the breaking off of a piece of otoconia from the otoliths. The otoconia floats freely in the inner ear fluid, causing disorientation and vertigo. [1] The disorder can be tested for using a nystagmus test, such as the Dix-Hallpike maneuver. This disorder can disrupt the ...
The vestibulo-ocular reflex is driven by signals arising from the vestibular system of the inner ear. The semicircular canals detect head rotation and provide the rotational component, whereas the otoliths detect head translation and drive the translational component.
