Neurophysiological studies for brain & nerve health.
VR Diagnostics offers EEG, NCV and EMG studies to assess brain activity, nerve conduction and muscle function — supporting diagnosis of seizures, neuropathy and neuromuscular conditions.
— What these studies measure
Reading the electrical activity of the brain & nerves.
EEG (electroencephalogram) records the brain’s electrical activity to help diagnose seizures and other neurological conditions. NCV (nerve conduction velocity) and EMG (electromyography) assess how well nerves and muscles are communicating — useful for diagnosing neuropathy, nerve compression and muscle disorders.
All studies are performed by trained technicians and reviewed by our specialists before your report is issued.
- Painless recording — EEG uses scalp electrodes, no needles involved.
- Detailed nerve mapping — NCV/EMG pinpoint where a nerve or muscle issue lies.
- Specialist-reviewed report — read before it reaches you.
Commonly ordered for
- Seizures & epilepsy work-up (EEG)
- Numbness, tingling or weakness (NCV)
- Suspected nerve compression, e.g. carpal tunnel
- Muscle weakness or disorders (EMG)
- Diabetic neuropathy assessment
— Before your study
How to prepare.
Before you arrive
Guidance
Hair & scalp (EEG)
Wash your hair the night before and avoid oils, gels or sprays on the day of your EEG.
Caffeine
Avoid caffeine and stimulants for a few hours before your study, if advised by our team.
Clothing (NCV/EMG)
Wear clothing that allows easy access to the limb being tested.
Medication list
Share a list of your current medications, especially any nerve or muscle-related prescriptions.
— Questions patients ask
Neurophysiological Studies — frequently asked questions.
Is an EEG painful?
No — electrodes are placed on the scalp with a paste, and the recording itself is completely painless.
Is NCV/EMG uncomfortable?
NCV involves a mild, brief electrical pulse and EMG uses a fine needle in the muscle — most patients describe it as mildly uncomfortable rather than painful.
How long does the study take?
A routine EEG or NCV/EMG study usually takes 30–60 minutes, depending on the number of areas tested.
Referred for an EEG, NCV or EMG?
Call the clinic or share your doctor’s referral and we’ll schedule your study.
