2023年3月30日 · The Dix-Hallpike maneuver is a test that healthcare providers use to diagnose benign paroxysmal positional vertigo (BPPV). BPPV is a common inner ear disorder that causes a sudden spinning sensation when you move your head into certain positions.

BPPV affecting the anterior semicircular canal (a -BPPV) has been controversial and is rarely seen, and a -BPPV accounts for up to 1-2% of cases. The clinical characteristics of a -BPPV is down-beating nystagmus with a less pronounced torsional component following DHP-testing or straight head-hanging.

2022年4月22日 · Ninety percent of BPPV occur in the posterior canal and present as torsional, geotropic, upbeating nystagmus during the Dix‐Hallpike (DHP) maneuver of the affected ear. 1 Five to fifteen percent involve the horizontal canal and is diagnosed by the Pagnini‐McClure maneuver, also known as the supine roll test. 2

Benign paroxysmal positional vertigo (BPPV) is the most common cause of positional vertigo. The term “benign” is consistent with a peripheral vestibular disorder that does not carry the potentially sinister sequelae of a central nervous system (CNS) cause.

Outcome measures: Negative Dix-Hallpike (DHP) or Supine roll test (SRT) examination. Results: In 91% of cases, PC BPPV was effectively treated in 2 manoeuvres or less. Similarly, 88% of HC BPPV presentations were effectively managed with 2 treatments. Bilateral PC, multiple canal or canal conversions required a greater number of treatments.

Canalith repositioning manoeuvres (CRP) for posterior canal (PC) or horizontal canal (HC) BPPV depending on the canal and variant of BPPV. Negative Dix-Hallpike (DHP) or Supine roll test (SRT) examination. In 91% of cases, PC BPPV was effectively treated in 2 manoeuvres or less.

Patients who experience both vertigo and nystagmus in the Dix-Hallpike test (DHT) are diagnosed with objective benign paroxysmal positional vertigo (BPPV). This test provokes only vertigo in between 11% and 48% of patients, who are diagnosed with subjective BPPV.

2021年3月10日 · Reversal of nystagmus on reversal of testing position is unusual but can occur. The Yacovino maneuver is effective in resolving AC BPPV. We also propose a hypothesis that explains why DHP testing is sensitive to AC BPPV on either side, whereas MCP lateral position on one side is only sensitive to AC BPPV on one side.

2021年9月1日 · Benign Paroxysmal Positional Vertigo (BPPV) is a common peripheral vestibular problem with a right ear and posterior canal predisposition. BPPV afflicts older adults beyond the age of 50 with a high prevalence between 71 and 80 years of age.
