What Is EMG/NCS?

Your pain management doctor in Winter Park, FL, can help you with EMG/NCS.

An EMG is an electromyogram, designed to measure the electrical stimulation of your muscles while at rest and when they are contracting. An NCS is a nerve conduction study, designed to measure how fast your nervous system sends electrical signals. These two tests are often performed in combination, to help diagnose nerve and muscle disorders.

Dr. Enrique Umpierre-Schuck at Central Florida Pain and Rehab Clinic in Winter Park, FL, offers comprehensive pain management services, including EMG/NCS to help you feel better.

EMG/NCS is an excellent diagnostic tool if you have:

  • Muscle weakness
  • Muscle cramping or muscle spasms
  • Nerve twitching
  • Muscle paralysis
  • Tingling or numbness in your face or extremities

For the EMG test, your doctor will test a muscle using an electrode. The electrode is placed into the muscle and the EMG machine will record your muscle activity while at rest. You need to tighten the muscle for the second measurement.

For the NCS test, several electrodes are taped on a nerve or nerves. The electrodes deliver an electrical pulse to your nerves. Electrodes are also attached to the muscles controlled by the nerves. The muscle reactions to the impulses are measured and recorded.

The EMG/NCS is tolerated well by most people, however, you may feel slight discomfort or cramping during the EMG part of the test, and slight tingling during the NCS part of the test.

EMG/NCS is used extensively to diagnose certain conditions, including:

  • Carpal tunnel syndrome
  • Disc herniation
  • Myasthenia gravis
  • Guillain-Barre syndrome
  • Muscular dystrophy
  • Amyotrophic lateral sclerosis (ALS)

EMG/NCS is an important tool in the early diagnosis of serious medical conditions. To find out more about EMG/NCS and other diagnostic and pain management services, call Dr. Umpierre-Schuck of Central Florida Pain and Rehab Clinic in Winter Park, FL, at (407) 673-9533 today!
