ENMG (Electroneuromyography)

Book an Appointment

What is ENMG?

Think of ENMG as a translator for the body’s electrical language. It uses a combination of two techniques:

  • Electromyography (EMG): This records the electrical activity of your muscles, revealing how they respond to nerve signals.
  • Nerve conduction studies (NCS): These measure the speed and strength of electrical signals traveling along your nerves.

By combining these, ENMG paints a detailed picture of the health of your nerves and muscles, helping doctors diagnose and understand the source of various neuromuscular problems.

What can ENMG Reveal?

This powerful tool can shed light on a wide range of conditions, including:

  • Nerve damage: Injuries, compression, or infections affecting nerves can be identified.
  • Muscle diseases: Weakness, wasting, and abnormal muscle activity can be investigated.
  • Autoimmune disorders: Conditions like myasthenia gravis, where the immune system attacks nerves, can be diagnosed.
  • Motor neuron diseases: Amyotrophic lateral sclerosis (ALS) and other disorders affecting the nerve cells controlling muscles can be assessed.


Benefits of ENMG:

  • Painless and non-invasive: No needles or injections involved, making it a comfortable procedure.
  • Accurate and objective: Provides objective data to support diagnosis.
  • Early detection: Can identify nerve damage early, leading to prompt treatment and better outcomes.
  • Treatment guidance: Helps doctors choose the most effective treatment strategy.


What to Expect During an ENMG:

The procedure usually takes 30-60 minutes and involves placing small electrodes on your skin. These electrodes pick up the electrical signals from your muscles and nerves. Mild shocks may be delivered to stimulate nerves and assess their conduction.

Understanding Your ENMG Results:

While the squiggles on the ENMG report might seem like a foreign language, your doctor can interpret them to pinpoint the source of your problems. Don’t hesitate to ask your doctor for explanations and clarifications about your results.

ENMG: Orchestrating a Path to Neuromuscular Health

ENMG is a valuable tool in the diagnosis and management of neuromuscular disorders. It allows doctors to listen to the body’s electrical whispers, decode their meaning, and ultimately, orchestrate a path towards improved health and mobility.
