Randomized Controlled Trial
A single Epley manoeuvre can improve self-perceptions of disability (quality of life) in patients with pc-BPPV: A randomised controlled trial in primary care.
Posterior canal benign paroxysmal positional vertigo (pc-BPPV) causes physical, functional, and emotional impairment. The treatment is the Epley manoeuvre (EM).

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. Detection of nystagmus has important diagnostic and prognostic implications. ⋯ Patients with subjective BPPV were more likely to be taking benzodiazepines [OR 0.24, p=0.023]. The prevalence of subjective BPPV was higher than expected. Cervical spondylosis and hypertensive therapy were associated with objective BPPV, while benzodiazepines were associated with subjective BPPV.
