Electromyogram (EMG) is a diagnostic tool used to test nerve conduction and electrical activity in the muscles surrounding the spine. An EMG is often used to find the precise source of back and neck pain as well as numbness or tingling in the extremities (radiculopathy).

During this test, small electrodes are placed on the skin and short electrical impulses are passed through the electrodes into the nerve or muscles. The reaction time and response of these muscles is used to determine precisely where the pain is being generated. The test is also used to determine if any permanent impairment or motor deficits have occurred due to nerve irritation or compression. This test is especially useful if a patient is considering a surgical procedure.

This non-surgical procedure is performed on an outpatient basis by the expert staff at the New Jersey Spine Institute and requires no anesthesia. We use this procedure as part of our comprehensive diagnosis process. At New Jersey Spine Institute, we believe that an accurate diagnosis is the first step to relief.

Why Get an Electromyogram?

An electromyogram is often one of the most accurate diagnostic tools for pinpointing the exact location and severity of injuries or disorders that affect muscles and/or nerves. If you are experiencing pain, weakness, tingling, loss of sensation, or reduced mobility in a specific region of your body, we may recommend an EMG to gather more in-depth information and develop the most comprehensive and effective treatment plan for your needs.

Conditions Diagnosed Through EMG

Many conditions can be diagnosed through EMG. Some of the most common include:

Myasthenia Gravis

Myasthenia Gravis (MG) is an autoimmune condition that chronically weakens the skeletal muscles, particularly those responsible for the eyes, mouth, throat, arms, and legs.

Herniated Disc

A herniated intervertebral disc can result in pinched nerves that cause radiating pain, weakness, or tingling throughout the upper or lower extremities, depending on the location of the disc. An EMG can help to accurately locate the issue and determine the extent of any nerve damage.

Muscle Disorders

Neuromuscular disorders that cause ongoing muscle degeneration over time, such as muscular dystrophy and polymyositis, can be diagnosed and evaluated using an electromyogram.

Peripheral Nerve Disorders

Peripheral nerve disorders impact the nerves located outside the spinal cord and often cause pain, muscle weakness, or numbness in the upper or lower extremities, including the hands and feet.

Your initial consultation will include an all-inclusive review of prior conservative and surgical treatment along with a comprehensive physical examination to develop an accurate diagnosis

What To Expect

Many patients wonder what to expect from an EMG procedure. At New Jersey Spine Institute, our highly qualified and experienced doctors perform EMGs on a regular basis and will perform the steps below while helping you remain as relaxed and comfortable as possible:

  • You will need to avoid smoking, sugar, and caffeine in the hours leading up to your EMG (we will provide you with detailed pre and post-instructions in advance).
  • Electrodes will be placed on your skin in the affected area.
  • A thin needle will be inserted into the affected muscle(s) and you may be asked to contract and relax so that your doctor can monitor the nerve signal response.

Known Risks

An electromyogram is considered to be a safe and effective procedure. That being said, patients may experience soreness at the site where the needle was inserted which gradually resolves over a few days. If bleeding or signs of infection occur (this is very rare), contact our team at New Jersey Spine Institute immediately.
