Advanced Module: Complex and Atypical BPPV
By the end of this module participants will be able to;
- Differentiate Complex Variants: Distinguish between typical canalithiasis and complex variants such as Anterior Canal BPPV, Heavy/Light Cupula, and Canal Jams based on nystagmus characteristics.
- Analyse Anatomical Subtypes: Identify short-arm (ampullary) versus long-arm (non-ampullary) canalithiasis in both Horizontal and Posterior canals and explain their impact on nystagmus direction (geotropic vs apogeotropic).
- Diagnose "Invisible" BPPV: Recognize Type 2 BPPV and "Sitting-up Vertigo" as distinct entities characterized by symptoms and truncal oscillation often without typical paroxysmal nystagmus during provocation.
- Master Advanced Lateralization: Apply advanced diagnostic protocols (Null Points, Bow and Lean, pseudo-spontaneous nystagmus) to lateralize Light Cupula and apogeotropic HC-BPPV when the Supine Roll Test is inconclusive.
- Apply Advanced Maneuvers: Select and execute appropriate maneuvers for specific variants, including the Short CRP for AC-BPPV, the Zuma maneuver for HC-BPPV, and the Shigeno correction to prevent postural crises.
- Evaluate Recurrence: Understand the random nature of BPPV recurrence patterns and the limitations of predicting future affected canals based on prior episodes.
This module includes a video lecture, multiple choice quiz, clinical reflections, and resources.
