**Core Concept**
Epley's maneuver is a series of movements performed to treat benign paroxysmal positional vertigo (BPPV), a condition that affects the vestibular system of the inner ear. BPPV is caused by the displacement of calcium particles (otoconia) from the utricle into the semicircular canals, leading to abnormal vestibular stimulation and vertigo.

**Why the Correct Answer is Right**
Epley's maneuver involves a series of five specific movements that help to relocate the displaced otoconia from the semicircular canals back to the utricle. The Canalsith repositioning procedure, a variation of Epley's maneuver, involves a sequence of position changes to move the otoconia from the posterior semicircular canal to the utricle. This is achieved by performing a series of Dix-Hallpike maneuvers, which involve moving the patient's head and body to specific positions to stimulate the vestibular system and allow the otoconia to settle back into the utricle.

**Why Each Wrong Option is Incorrect**
**Option A:** There is no evidence to suggest that Epley's maneuver is effective in treating peripheral vestibular disorders other than BPPV.
**Option B:** The canalith repositioning procedure is a specific variation of Epley's maneuver, not a separate treatment for BPPV.
**Option C:** The Brandt-Daroff exercises are a different treatment for BPPV that involve a series of head movements to help alleviate symptoms.

**Clinical Pearl / High-Yield Fact**
Epley's maneuver is most effective when performed as soon as possible after the onset of symptoms, as delayed treatment can lead to prolonged recovery times and increased risk of recurrence.
