Table 2. Summary of Key Action Statements (KAS)
Diagnosis of posterior canal BPPV
Clinicians should diagnose posterior semicircular canal BPPV when vertigo associated with torsional, up-beating nystagmus is provoked by the Dix-Hallpike maneuver, performed by bringing the patient from an upright to supine position with the head turned 45º to one side and neck extended 20º with the affected ear down. The maneuver should be repeated with the opposite ear down if the initial maneuver is negative. ( Strong Recommendation (S) , B )
