How to Set Up an EMG/NCV Lab: Room, Equipment and Workflow
A well-planned EMG lab gives accurate results and comfortable patients. Here is a practical blueprint.
Room
- About 10–12 m² with space around the couch for the trolley and the operator.
- Warm, because cold limbs falsely slow conduction.
- Away from heavy electrical equipment.
- Privacy screen and a hand-wash station.
Electrical
- Properly earthed sockets.
- Online UPS for the EMG and PC.
- Keep mobile phones and other devices away during recording.
Equipment checklist
| Item | Notes |
|---|---|
| EMG/NCV/EP system | 2 channel or 4 channel |
| Stimulator(s) | Handheld bipolar stimulators |
| Surface electrodes | Disc or disposable adhesive |
| Concentric needles | Single-use |
| Ground electrodes | Strap or adhesive |
| LED goggles / headphones | For VEP and BAER |
| Skin thermometer and warmer | Temperature control |
| Measuring tape | Accurate distances |
| Couch and pillows | Patient comfort |
| Sharps container | Safety |
Protocols and reference values
- Use standard protocols for common referrals (CTS, diabetic neuropathy, radiculopathy, GBS).
- Use the software’s normative values, then build your own lab norms over time.
- Use report templates for consistency.
Workflow
- Referral with a clinical question.
- Explanation and consent.
- Limb temperature check and warming.
- NCS, then EMG if needed.
- Analysis with auto-markers and review.
- Report with an interpretation that answers the clinical question.
Infection control
Use single-use needles, clean surfaces between patients and dispose of sharps safely.
Training
Hands-on application training is essential, especially for EPs and difficult nerves. RS Enterprises includes training with every installation and offers refresher sessions.

Frequently Asked Questions
What room temperature is ideal?
Keep the room warm and measure limb temperature; warm cold limbs before testing.
Are disposable needles mandatory?
Single-use concentric needles are standard for infection control.
How many patients can one lab handle daily?
Depends on test complexity; a routine NCS/EMG takes 30–60 minutes.
