What are nerve conduction studies used to diagnose?

EMG and nerve conduction studies are used to help diagnose a variety of muscle and nerve disorders. An EMG test helps find out if muscles are responding the right way to nerve signals. Nerve conduction studies help diagnose nerve damage or disease.

What are the three types of nerve conduction studies?

There are three types of NCS, motor, sensory, and mixed (Fig. 1). Because of differing technical aspects in their performance, these must be performed sequentially, rather than simultaneously, whenever the same mixed nerve is being assessed (ie, motor and sensory NCS cannot be done on a nerve trunk at the same time).

Why would a doctor order a nerve conduction test?

Your doctor may recommend a nerve conduction test to find the cause of muscle or nerve symptoms. This includes stiffness, weakness, spasticity, numbness, tingling or pain. The test can evaluate nerve and muscle diseases and conditions including: ALS (amyotrophic lateral sclerosis) and myasthenia gravis.

What is the most common symptom of nerve damage?

If you have neuropathy, the most commonly described feelings are sensations of numbness, tingling (“pins and needles”), and weakness in the area of the body affected. Other sensations include sharp, lightening-like pain; or a burning, throbbing or stabbing pain.

What happens if you have nerve damage?

Damage to the nerves can make it harder to control muscles. It can also cause weakness. You may notice problems moving a part of your body. You may fall because your legs buckle.

What does a nerve conduction study feel like?

Nerve conduction studies show how well the body’s electrical signals travel down your nerves. During a nerve conduction study test, providers apply small electrical shocks to your nerve and record how your nerve works. These shocks cause a quick, mild tingling feeling that feels like a static or “carpet” shock.

How much does a nerve conduction study cost?

The cost for a Nerve Conductivity Study can range from $1,000 to $2,500. If you have Health Insurance with a low deductible it should cover most of the cost. If you have a high deductible Health Insurance Plan, you will likely be footing most of the bill for this test.

What to expect during nerve conduction study and EMG test?

During a needle EMG, a needle electrode inserted directly into a muscle records the electrical activity in that muscle. A nerve conduction study, another part of an EMG, uses electrode stickers applied to the skin (surface electrodes) to measure the speed and strength of signals traveling between two or more points.

What happens during a nerve conduction study (NCS) procedure?

What happens during a nerve conduction study (NCS) procedure? The technician puts electrode patches on your skin over the nerve that may be causing your symptoms. A stimulating electrode sends a mild electrical impulse to the nerve. The other electrodes record the nerve’s response.
