Learn nerve conduction studies by doing them.

StimCoach is a web-based NCS/EMG technique trainer. Place electrodes on lifelike 3D limbs, set your stimulus, and read waveforms generated by a real conduction model — from median motor to H-reflex, normal to pathology.

Free includes the median motor & median sensory studies and a live LesionLab™ demo — no account, no card.

The parts of the exam you can't learn from a book

Video courses show you someone else's hands. Question banks test what you already read. StimCoach puts the probe in your hand and the trace on your screen.

Real placement geometry

Electrodes, ground, and stimulation sites on photographed and 3D limbs with true surface distances — measuring tape included. Off-motor-point placement changes the trace, just like at the bedside.

A waveform engine, not clip art

Responses are computed: stimulus intensity, temperature, filters, artifacts, and pathology — axonal loss, demyelination, conduction block, temporal dispersion — all shape the trace the way physiology does.

Late responses too

F-waves with per-fire variability, and the tibial H-reflex — the studies learners see least and fear most, ready to repeat as many times as it takes.

Technique before interpretation

Anti-dromic vs orthodromic, belly–tendon montages, distance discipline, supramaximal stimulation — the trainer grades the setup, not just the answer.

LesionLab™ — plexus localization you can touch

The brachial plexus, from roots to terminal nerves, as an interactive map. Click a lesion site, set severity and chronicity, and see what it does to every study at once. New — the Axons view: full versus partial loss in plexus lesions, made visible.

Anatomy that tells the truth

Roots split at the dorsal root ganglion so pre- vs post-ganglionic sensory sparing falls out of the anatomy — not a footnote. Trunks, divisions, cords, terminal branches, and labeled collaterals.

Real waveforms per site

Every stimulation site of every affected study renders through the same engine as the simulator — measured amplitudes judged against each study's own normal values.

EMG table + discriminators

Muscle-by-muscle EMG findings, paraspinal logic, root myotomes, and side-by-side comparisons of look-alike lesions — C8 root vs lower trunk, and friends.

Questions

Is this a subscription?

No. A pass is one payment for 12 months of access. When it ends, nothing renews by itself — your account simply drops back to the free tier until you buy another pass.

What do I get for free?

The free tier runs without an account — just open the simulator. It includes the median motor and median sensory studies in all four modes, enough to run a full study end-to-end and see exactly how StimCoach teaches before you pay. You also get a live LesionLab™ demo: the Erb’s palsy preset with working severity and chronicity controls, so you can watch the waveforms and EMG table respond before unlocking the full module. The new Axons (fascicular) view works in the demo too. An account is created automatically when you buy a pass.

Does it run on my machine?

StimCoach runs in a modern desktop browser — nothing to install. The 3D limbs use WebGL, which every current Chrome, Edge, Firefox, and Safari supports.

Can my program or department get access?

Yes — group licenses with invoicing are available. Email support@stimcoach.com and tell us how many seats you need.

Something isn't working / refunds?

Email support@stimcoach.com and we'll make it right.
