Electrodiagnostic medicine, taught on real EMGs
A graduate-level course in EMG and nerve conduction studies for residents, fellows, and neurodiagnostic technologists. Every concept is paired with a real recording you can interact with or a biophysical model you can drive yourself.
Healthy control: Crisp tri/biphasic MUAPs around 0.5–1 mV that recruit smoothly as effort rises.
44 y/o male · Tibialis anterior · concentric needle · No history of neuromuscular disease. Real recording · 4 kHz.
Press play, switch between the healthy, myopathic, and neuropathic recordings, and turn on the audio — EMG is an exam you read by ear as much as by eye.
Real EMG recordings
Genuine concentric-needle recordings — healthy, myopathic, and neuropathic — that you scroll, zoom, measure, and listen to. Not illustrations: real microvolts at 4 kHz.
Live biophysical models
A Hodgkin–Huxley membrane, a recruiting motor-unit pool, a CMAP with draggable calipers, repetitive stimulation — all integrated live in your browser, not pre-rendered.
Built for residents & techs
PhD-level rigor mapped to the way you actually work up a study: foundations, instrumentation, NCS, needle EMG, and clinical localization.
Free for everyone, forever
No login, no paywall, no tracking. An open educational resource for the global neuromuscular community.
Nine pillars, ion channels to diagnosis
Electrophysiology of Motor Systems
From ion channels and the anterior horn cell to the recorded waveform.
Nerve Conduction Studies
Stimulate, record, measure — and convert numbers into localization.
Needle EMG Physiology
The needle examination, decoded from rest to full effort.
Neuromuscular Disease Mechanisms
The biology that generates the signals — from axon to muscle membrane.
Clinical Electrodiagnostics
Turning mechanism into localization, diagnosis, and prognosis.
Advanced Electrophysiology
Beyond routine: single-fibre, quantitative, intraoperative, and pediatric methods.
Signal Analysis & Computational EMG
The mathematics and machine learning beneath the waveform.
Diagnostic Reasoning in EMG
The cognitive engine: pattern, probability, and pitfall.
Integrated EMG Medicine
The capstone synthesis — EMG as a functional assay of the motor unit.
Start where the signal is real.
Begin with the biophysics of the action potential and work up to reading real needle recordings like a clinician.
