Classic Findings During Hallpike Test in Posterior Canal Benign Paroxysmal Positional Vertigo (BPPV)

 • Latency (delay in nystagmus and vertigo once in head-hanging position) of approximately 3 to 10 seconds, although delay can take up to 30 seconds on rare occasions

 • Reproduction of vertigo symptoms in head-hanging position

 • Upbeat (fast phase toward forehead) and torsional nystagmus (usually toward the downward ear)

 • Vertigo and nystagmus escalates in head-hanging position, then slowly resolves over 5 to 30 seconds

 • Nystagmus and vertigo may reverse direction when patient returns to sitting position

 • Nystagmus and vertigo decrease with repeated testing (fatigability)
