Module 11
Pattern recognition trainer A random VEMP signature appears. Tick every finding you observe, then reveal. Each round is a fresh case drawn from the disease archetypes used elsewhere in this atlas — so the cases are infinite, but every one is medically realistic.

0 10 20 30 40 50 Time (ms) Normal Affected ear Which findings are present? Reduced amplitude Amplitude well below the normal range, but a response is still present. Augmented amplitude Amplitude clearly above the normal range — the third-window signature. Absent response (one side) One side gives effectively no response (< 2 µV). Prolonged latency Peak latency delayed beyond normal — implies central (brainstem) conduction. Asymmetric (large L/R difference) Big difference between left and right (interaural asymmetry > 35–40%). Lowered threshold Response still present at low stimulus levels — extra energy admitted by a 'third window'. Frequency-tuning shift Best response shifted away from 500 Hz toward 1 kHz — characteristic of hydrops. Reveal diagnosis Skip this case
