These are commonly preformed procedures that are a
direct extension of the physical examination. They detect nerve and muscle
disorders.
-
An EMG specifically tests the electrical activity of
the muscles. Disposable pin electrodes are inserted into the muscle to
record their activity.
-
A NCV specifically tests how well signals travel along
a nerve and the time it takes muscle to respond to these signals.
Stimulating and recording electrodes are used on the surface of the skin.
-
To evaluate the causes of numbness, tingling, pain,
weakness, fatigue, spasms, and paralysis.
-
To diagnose carpal tunnel syndrome, muscular dystrophy,
fatigue, myasthenia gravis, ALS (Lou Gehrig’s disease), and pinched
nerves.
-
To determine if the problem involves the muscles,
nerves, spinal cord or brain.
-
Shower on the day of your test to remove body oils.

skin infection.
-
RELAX. Tension and anxiety can interfere with your

-
Dr. Munderloh will take your medical history. You will
be asked to describe symptoms, past illnesses and accidents.
-
The whole office visit should take approximately an
hour and a half.
-
Does an EMG hurt? The procedure is
uncomfortable, but not extremely painful. Most people tolerate this minor
level of pain quite well.
-
Is the stimulus given during a NCV painful?
Most people feel an unusual tingling sensation. Some may experience
slight, temporary pain or discomfort.
-
How do I pay for these tests? Most health
insurance, worker compensation and third-party liability claims cover the
costs of these tests. Your benefits will already be verified before you
visit Dr. Munderloh’s office.
