An Interactive Teaching Atlas
A clinical‑editorial atlas for cVEMP and oVEMP — written for medical students, audiology and ENT trainees, and practising clinicians. Each module reads at three levels, with hand-drawn diagrams, an interactive waveform laboratory, and a peer-reviewed self-assessment.
How to use this atlas
Choose a reading level in the sidebar — Foundation for a brief, plain-language overview, Trainee for the working level expected in clinical training, or Clinician for the deeper detail and evidence base used in practice. Your progress and notes are kept in your browser; nothing is uploaded.
Core modules
What VEMPs measure, why they matter, and a brief history.
Saccule, utricle, the two divisions of the vestibular nerve, and the reflex arcs.
Stimuli, electrode placement, parameters, EMG correction, common pitfalls.
Interactive wave simulator, normative ranges, the IAR explained.
Disease conditions
Third-window VEMP signature — lowered threshold, augmented amplitude.
Endolymphatic hydrops — reduced amplitudes and frequency-tuning shift.
Topographic diagnosis: superior vs inferior vs total neuritis.
VEMP in vestibular migraine — common but heterogeneous abnormalities.
Benign paroxysmal positional vertigo — utricular VEMP findings.
Sensitivity ~81%, specificity ~53% — adjunct to MRI work-up.
Central demyelination — latency prolongation, even with normal MRI.
Study tools
Bedside-style scenarios — vignette, tests, single-best-answer diagnosis, and a teaching point.
Question bank tagged by difficulty — Foundation, Trainee, Clinician.
Definitions of every term used across the atlas.
Full peer-reviewed reference list.
Pick any two VEMP signatures and see them next to their normal references.
Endless random cases — read the trace, mark the findings, reveal the diagnosis.
A dashboard view of everything the atlas remembers locally — quizzes, decks, cases, bookmarks, time on each chapter.
Atlas changelog — features, content updates, fixes, in reverse chronological order.
