Electrodiagnostic Testing

Electrodiagnostic Testing reads the electrical signals traveling from your brain to your nerves and muscles, helping diagnose the cause of weakness, numbness, tingling or pain.

What It Measures

Nerve signal speed & intensity

Position

Lying down

Sensation

Painless, mild tingling possible

Method

Electrodes along the nerve path

Electrodiagnostic Testing

For disorders affecting the nerves and muscles, Electrodiagnostic Testing is an invaluable tool which is used to help establish a diagnosis and determine the severity of a Neuro-Muscular problem. Electrodiagnostic Testing specifically reads the electrical signals that travel from the brain to motor/sensory nerves to muscles. An injury or disease can interrupt these electrical signals and can be noted in anyone who experiences weakness, atrophy, fatigue, cramps, abnormal muscle movements, burning, stiffness, numbness, and tingling.

At Wesley Chapel Spine and Sports Medicine we are proud to offer Electrodiagnostic Testing which measures the speed and intensity of these electrical signals which travel along the nerves. It also tests reaction time for a response which can help our skilled physicians determine where along a nerve pathway a blockage may be.

During the test, patients are usually asked to lie down. Small electrodes are then placed along the course of the nerve that’s being tested and mild electrical impulses are sent along the course of a nerve in the arm or the leg. These impulses then measure response times, also known as conduction velocities. A healthy nerve will transmit this signal faster and stronger than an injured nerve. The test is typically painless but patients may experience a tingling sensation or some muscle twitching.

Electrodiagnostic Testing

This testing is used to diagnose carpal tunnel syndrome, sciatica, radiculopathy, and peripheral neuropathy often caused by diabetes or autoimmune disease. It can detect subtle nerve damage that may not be visible through X-rays, MRIs or CT scans, and is also used to diagnose neuromuscular diseases such as ALS, Multiple Sclerosis, and Guillain-Barré Syndrome.

The testing process typically takes less than 30 minutes and can also help differentiate between muscular disorders and neurological disorders — useful for athletes with sports injuries such as tennis elbow, rotator cuff injuries, or sciatica, and for pre-operative evaluations before surgeries like spine surgery or joint replacements.

Your Testing Visit, Step by Step

1

Lying Down

You’ll be positioned comfortably so the arm or leg being tested is accessible.

2

Electrode Placement

Small electrodes are placed along the course of the nerve being tested.

3

Mild Impulses

Gentle electrical impulses measure conduction velocity — painless, though tingling or twitching may occur.

4

Results Reviewed

Signal speed and strength are compared to healthy nerve function to pinpoint any blockage.
