EMG Q & A

What is an EMG?

EMGs measure and evaluate the function and health of your nerves and muscles. EMGs are noninvasive and painless tests that help your neurologist to identify the cause of nerve and muscle malfunction in your body.

Why would I need an EMG?

Your neurologist at JKC Neurology Medical Group may order an EMG if you experience symptoms such as:

  • Numbness or tingling
  • Muscle weakness
  • Involuntary muscle twitching
  • Muscular pain or cramping
  • Paralysis

An EMG allows your doctor to assess your nerve function and the communication between your nerves and muscles. Some of the conditions that cause these issues include:

  • Muscular dystrophy and other muscle disorders
  • Peripheral nerve disorders such as carpal tunnel syndrome
  • Amyotrophic lateral sclerosis (ALS) and other nerve disorders
  • Conditions that disrupt the communication between motor neurons and muscles
  • Radiculopathies

Getting an accurate diagnosis is critical to starting treatment to relieve your symptoms, restore your function, and improve your overall health. An EMG can help your neurologist provide a customized treatment plan to address your needs.

How should I prepare for an EMG?

Your neurologist gives you specific instructions on how to prepare for your EMG. In general, you should wear comfortable clothing and avoid smoking for several hours before your appointment. 

Your doctor will ask you to shower before you come to the office to clean any oils from your skin. You also shouldn’t apply any creams or lotions on before your appointment.

Make sure to let your neurologist know about any medications, vitamins, or supplements you take and if you have a pacemaker or implantable defibrillator.

What happens during an EMG?

EMGs have two parts: A nerve conduction study and a needle EMG. The whole test takes between 30-60 minutes and is performed right in the JKC Neurology Medical Group office.

Your doctor usually performs the nerve conduction study first. They attach electrodes to your skin on the part of your body where you have the symptoms. The electrodes monitor and record the electrical activity in your muscles, gauging how well your nerves are communicating with your muscles.

During the needle EMG, your doctor inserts a few needle electrodes into your muscles. The needles measure the electrical activity in your muscles when they’re at rest and when they contract.

After your EMG, you can resume your day immediately and carry on with your regular activities.
