Are nerve conduction studies accurate?

The global accuracy of the test was 61%. In all of the patients with probable CIPNM and abnormal echogenicity, the sural and peroneal single NCS were both abnormal.

Is nerve conduction study expensive?

The Nerve Conduction Study is relatively expensive and offers no therapeutic value. In other words, the test doesn’t help you get better. It can cost up to $1200. Even with Health Insurance your share of the cost can be substantial with deductibles and copays.

What do nerve conduction studies reveal?

Nerve conduction studies show whether the nerves transmit electrical impulses to the muscles or up the sensory nerves at normal speeds (conduction velocities). Sensory nerves allow the brain to respond to pain, touch, temperature and vibration. Different nerves have different normal conduction velocities.

Does insurance cover nerve conduction study?

EMG testing is typically covered by health insurance. For patients with health insurance, there may be a copay of $10-$50 or coinsurance of about 10%-50%. For patients without insurance, the test typically costs between $150 and $500 per extremity, depending on the health care provider.

How painful is a nerve conduction study?

As the nerve is stimulated, you will experience a brief electrical shock. This may feel uncomfortable, but it usually isn’t painful. The entire procedure usually takes about 20-30 minutes to complete. In some cases, nerves may be tested in multiple locations, which can make the procedure take slightly longer.

What should you not do before a nerve conduction study?

Do not eat or drink foods that contain caffeine (such as coffee, tea, cola, and chocolate) for 2 to 3 hours before the test. Wear loose-fitting clothing so your muscles and nerves can be tested. You may be given a hospital gown to wear. Take a shower or bath before your exam to remove oils from your skin.

Can you drive after a nerve conduction study?

You may need to stay in the outpatient facility or hospital for a short period after your EMG. Your team will apply warm compresses to your injection sites to reduce pain. You will not be able to drive for about 24 hours if you had sedation because you will still be drowsy.

Why was my EMG so painful?

Pain is commonly associated with EMG, because the procedure involves the use of needles and electric shock. Not only friends and relatives who have had a previous EMG experience, but also physicians can sometimes discourage patients from undergoing EMG, believing that the test is very painful and of little benefit (1).
