How to use this atlas

A five-minute tour of the features that make this atlas worth more than a textbook chapter.

Set your reader level first

In the sidebar, set the reader level — Foundation, Trainee, or Clinician. Each disease page carries layered content: the Foundation layer is what a final-year medical student needs; the Trainee layer adds mechanism and pattern recognition; the Clinician layer adds nuance, surgical considerations, and the rarer presentations.

The setting persists across visits. Sections marked at a higher level than your current selection collapse on the page; they reappear when you raise the level.

A reasonable reading path

If you have a free hour, work through the modules in order: Introduction Anatomy & physiologyTechnique Normal findings → the disease pages, starting with vestibular neuritis.

If you have ten minutes, do the first three cases and read the teaching points; they cover most of the diagnostic logic.

The interactive tools

SVV simulator— drag the luminous line until you think it’s vertical, then reveal the angle. Try presets for each disease to feel the tilt magnitudes in degrees rather than in words.

Compare— pick any two disease signatures and overlay them on one bucket. Useful for teaching Ménière’s versus migraine, or peripheral neuritis versus Wallenberg.

Pattern trainer — infinite cases drawn from nine disease archetypes. Tick the findings you observe, reveal, see what you missed and what you over-called. Stats persist; play five rounds a day for a week.

Practice and revision

Self-assessment has three modes:

  • Browse — page through every question with rationales visible.
  • Spaced — Leitner schedule (10 min → 1 d → 3 d → 7 d → 21 d intervals). Right answers promote a card up a box; wrong answers send it back to box 1. Come back tomorrow.
  • Timed — 10 random questions in 5 minutes, answers hidden until you finish. Personal best persists.

Clinical cases are hand-authored with full vignettes and single-best-answer questions. Filter by reader level and work through them in order.

Bookmarks and progress

Star any term in the glossary to bookmark it. All bookmarks, quiz personal bests, trainer stats, completed cases, and visited chapters appear on the My progresspage. The data is stored in this browser’s localStorage; nothing is sent to a server.

Listen, don’t read

Eleven modules carry an inline narrated walkthrough — a 2.5–4.5 minute summary of the chapter in plain speech, with timestamped transcript visible on the page. If an audio file has been recorded, the player wires up automatically. If not, the transcript alone is the canonical content.

Save the whole atlas as a PDF

The Print allroute compiles every module, every case, the glossary, and the references into a single document with a cover page and contents. From there, your browser’s “Save as PDF” produces a self-contained file you can read offline or hand to a trainee.

Individual chapters can also be printed from the same browser dialog; each page is print-styled with A4 margins and orphan/widow control.

Feedback

The Feedbackbutton in the bottom-right of every page opens an email pre-filled with the page URL. If you spot a typo, a wrong citation, or a missing topic, click it. The atlas improves only when people who use it tell us where it doesn’t work.

Subjective Visual Vertical

An interactive teaching atlas of Subjective Visual Vertical for the assessment of otolith-graviceptive function — bucket and digital technique, dynamic SVV, normal findings, and the tilt signatures of peripheral and central vestibular disease. Content synthesised from current Bárány Society criteria, peer-reviewed vestibular literature, and standard otoneurology texts.
