IENA Neurophysiologie offers comprehensive assessments for disorders of the peripheral nervous system and muscles.
Our investigations — electromyography (EMG), somatosensory evoked potentials, SudoScan, and specialist consultations — are performed by an expert neurologist in a practice fully dedicated to clinical neurophysiology, located in the heart of the 16th arrondissement of Paris.
Each examination is preceded by a medical consultation and followed by a detailed report provided immediately to you and sent directly to your referring physician.
Electromyography (EMG)
The gold standard diagnostic test for evaluating nerves and muscles
⏱ Duration: 30 to 60 minutes
📋 Medical prescription required
🧴 Please avoid applying body lotions or creams to your limbs on the day of your examination
📄 Medical report provided immediately

Facial EMG
Neurophysiological assessment of facial palsy and the facial nerve (CN VII)
Facial EMG examines the facial nerve (VII) and the trigeminal nerve (V), as well as the muscles of the face and tongue.
It combines a study of facial nerve conduction (painless stimulation in front of the ear), the study of the blink reflex (which explores the trigemino-facial reflex arc), and, if necessary, needle electromyography of the facial and lingual muscles.
Main indications:
· Peripheral facial palsy (Bell's palsy, Ramsay Hunt syndrome)
· Monitoring and prognosis of recovery following facial palsy
· Hemifacial spasm
· Ptosis - Myasthenic syndrome
· Tongue mobility disorders / dysphagia / dysarthria
· Suspicion of compression or neuropathy of the facial nerve or trigeminal nerve
The examination can be combined with an EMG of the upper and/or lower limbs if a generalised neuropathy or myopathy is suspected.
⏱ Duration: 20 to 40 minutes
📋 Medical prescription required
🧴 Please avoid applying creams, oils, or make-up to the face on the day of your examination
📄 Medical report provided immediately

Somatosensory Evoked Potentials (SEP)
Explore the sensory pathways of the central nervous system
⏱ Duration: 45 to 60 minutes
📋 Medical prescription required
✅ Painless procedure
📄 Report provided immediately

Motor Evoked Potentials (MEP)
Investigating the pyramidal motor pathways of the central nervous system
⏱ Duration: 20 minutes
📋 Medical prescription required
✅ Painless examination
📄 Report provided immediately

SudoScan
-
Electrochemical Skin Conductance
⏱ Duration: 15 minutes
📋 Medical prescription required
✅ Completely painless examination — no prior preparation required
📄 Immediate results

📋 Medical referral letter required
🔗 Can be combined with an EMG
📄 Report forwarded to the referring doctor and your primary care physician

Second neurological opinion

Is it necessary to fast before undergoing an EMG or a SudoScan?
No. None of the examinations carried out at IENA require you to fast. You may eat and drink as normal prior to your appointment.
How long does an electromyogram procedure take?
An EMG typically takes between 20 and 40 minutes, depending on the scope of the prescribed assessment. The medical report is prepared and provided to the patient immediately following the examination.
Will my medical examination be eligible for reimbursement?
We offer direct billing (tiers-payant) with the French National Health Insurance and complementary health funds for EMGs, evoked potentials, and consultations. You will only need to pay the doctor's surcharge (dépassement d’honoraires) upfront. Please note that SudoScan is not covered by the French National Health Insurance. We advise you to contact your private health insurance provider to check for any potential coverage.
Is the EMG painful?
The nerve conduction study (the first part of the EMG) may cause mild discomfort. Needle detection (the second part) is less painful than a blood test. The examination is well tolerated by the vast majority of patients.
Is it possible to schedule both an EMG and a SudoScan on the same day?
Yes. It is possible to undergo multiple examinations during a single visit — including EMG, SEP, and SudoScan — as well as a neuromuscular consultation if required. This is designed to save you from making multiple journeys. Please note that this must be arranged in advance.
Should I bring anything to my appointment?
Please bring your doctor's prescription or referral letter, your Vitale card (if applicable), your medical history, and any previous test results (such as MRI scans, lab reports, or clinical summaries). For the EMG, please do not apply any moisturising creams or lotions to your arms and legs on the day of your examination.
