Nerve problems can cause pain, unpleasant sensations, and loss of both feeling and function in any part of your body. Double board-certified physiatrist Dr. Javier Placer, MD, and his team at Specialized Rehabilitation Physicians Group in Clermont and Orlando, Florida, are experts in using electrodiagnostic medicine techniques like EMG (electromyogram) and NCV (nerve conduction velocity) studies to find the causes of nerve pain. If you think you have nerve problems, call Specialized Rehabilitation Physicians Group today or book an appointment online.
EMG / NCV Studies Q & A
What are EMG and NCV studies?
EMG and NCV studies are both forms of electrodiagnostic medicine. Dr. Javier Placer, MD, uses electrodiagnostics to diagnose, evaluate, and treat patients who have problems with nerve function.
EMG is short for electromyogram. Dr. Javier Placer, MD, uses the EMG technology to measure the electrical signals in your muscles to see if any nerves aren’t working as they should. He inserts very slim needles into precise points in your muscles. The EMG machine records the electrical signals and creates a readout for Dr. Javier Placer, MD, to analyze.
NCV is short for nerve conduction velocity. Dr. Javier Placer, MD, uses a carefully measured electrical current to activate certain nerves. He can then measure how quickly and efficiently your nerves are responding.
EMG and NCV studies are typically done at the same time, to give Dr. Javier Placer, MD, a clear picture of how your nerves are functioning and highlight any problems.
How do EMG and NCV studies help diagnose nerve problems?
When your body is working as it should, your nerves send messages to each of your muscles to tell them what they should be doing. These messages come from your brain and spinal cord (central nervous system).
These messages might be a response to you thinking about a deliberate action like getting dressed or preparing a meal, or they might be involuntary like the beating of your heart.
Every message from your central nervous system to your nerves and then from your nerves to your muscles uses electricity, so measuring the speed and strength of the electrical activity can help pinpoint the cause of your nerve condition.
Sometimes the nerves aren’t receiving the right messages, and sometimes they aren’t sending out the right signals to your muscles, which can cause pain, lack of function, and unpleasant sensations like:
- Pins and needles
Dr. Javier Placer, MD, has specialist expertise in conducting and interpreting EMG and NCV studies to help diagnose the cause of your symptoms.
What might EMG and NCV studies show?
EMG and NCV studies can help Dr. Javier Placer, MD, diagnose conditions like:
- Amyotrophic lateral sclerosis (ALS)
- Carpal tunnel syndrome
- Myasthenia gravis
- Nerve complications
- Peripheral neuropathy
- Pinched nerves
