The study introduces the upright head roll test (UHRT) as a diagnostic tool for lateral semicircular canal benign paroxysmal positional vertigo (LSC-BPPV) and evaluates its reliability and validity. Through two separate studies involving 827 videonystagmography (VNG) results and 130 LSC-BPPV cases, the research found substantial to almost perfect agreement between UHRT and the traditional supine head roll test (SHRT) in identifying and distinguishing the direction of direction-changing positional nystagmus (DCPN). UHRT demonstrated high accuracy in diagnosing LSC-BPPV (80.0%) and its variant types (74.6%), particularly the canalolithiasis type with a Cohen’s kappa of 0.835. However, it showed moderate accuracy for the cupulolithiasis type (Cohen’s kappa = 0.415) and a limitation in determining the affected side due to a weaker nystagmus intensity compared to SHRT. This study highlights UHRT’s potential as a reliable diagnostic maneuver for LSC-BPPV, despite some limitations.
