Electrodiagnostic Testing: Have You Been Injured?

If you’ve been injured in an accident, doctors may order testing to help them determine the course of your treatment. CT Scans, MRIs, X-Rays are some of the tests a doctor will order, depending on the injuries you’ve sustained. Also utilized are electrodiagnostic tests.

What is electrodiagnostic testing?

Beneath the surface, and quite microscopically, the nerves of the human body are sending messages to and from the brain and muscles using sensory nerves and motor nerves. But these “messages” being sent are actually electrical signals. And if the human body suffers an injury, the damage done may cause these electrical signals to slow down or stop entirely.

In determining the extent of the damage and make an informed diagnosis, doctors may order electrodiagnostic testing to measure the activity of your electrical signals.

Electrodiagnostic tests have two common forms, electromyography (EMG) and nerve conducting studies (NCS):

Electromyography (EMG)

An EMG is used to analyze the electrical impulses in your muscles. Usually the muscles in your limbs. The doctor will insert narrow needles into your muscles (which may cause some pain or discomfort, but it won’t be excruciating). The needles will pick up the activity of your signals and project the activity onto a screen for the doctor to view. He or she will instruct you to tense up your muscles or relax them to display the range of your signal activity.

Nerve Conduction Studies (NCS)

NCS is usually performed in conjunction with EMG testing to monitor the function of the nerves. The doctor will attach (often using tape) electrodes to your skin. The electrodes will be placed on different parts of your body, and they will analyze how fast electrical currents pass through each area. If injury has occurred, the electrical signals will not be as strong as they should be.

A doctor may have you submit to electrodiagnostic testing, such as an EMG and / or NCS, if you have been involved in a number of accidents. Electrodiagnostic testing may be used following a car crash, truck accident, motorcycle collision, or fall down accident to measure the extent of your injuries.
