The \u201cbow and lean test,\u201d and several methods built upon it, have been proposed. Many of these techniques are based on a model in which the horizontal canal\u2019s putative anatomy involves an anteromedial segment. The actual anatomy has a posteromedial segment. We show that predictions of a model based on the hypothetical anatomy differ from those based on the true anatomy. We further show that the true anatomical model predicts that for a roll maneuver that begins in the supine position, going from the side-lying position to the prone position should generate different patterns of nystagmus depending on which side is affected; this should distinguish which side is affected, and thus has implications for treatment. We conclude with a data visualization method that depicts these findings compactly.<\/jats:p>","DOI":"10.1007\/s00415-025-13450-0","type":"journal-article","created":{"date-parts":[[2026,1,13]],"date-time":"2026-01-13T11:41:58Z","timestamp":1768304518000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Bow and lean test reconsidered: anatomy, predictions, and a data visualization method for\u00a0horizontal canal BPPV"],"prefix":"10.1007","volume":"273","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9371-4488","authenticated-orcid":false,"given":"Marcello","family":"Cherchi","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2026,1,13]]},"reference":[{"key":"13450_CR1","first-page":"277","volume":"25","author":"G Asprella Libonati","year":"2005","unstructured":"Asprella Libonati G (2005) Diagnostic and treatment strategy of lateral semicircular canal canalolithiasis.
