What is Electromyography (EMG)?

Electromyography (EMG) is a diagnostic procedure used to assess the health of muscles and the nerves that control them. It measures the electrical activity of muscles in response to nerve stimulation, helping identify nerve or muscle dysfunctions.

Conditions Treated

  • Nerve compression or injury (such as carpal tunnel syndrome)
  • Neuropathy
  • Radiculopathy (pinched nerve)
  • Muscle disorders (such as muscular dystrophy)
  • Amyotrophic lateral sclerosis (ALS)
  • Peripheral nerve disorders

How Does the Procedure Work?

During the procedure, small electrodes are inserted into the muscle to measure electrical activity during rest and muscle contraction. The results help identify abnormal electrical signals indicating nerve or muscle damage.

What to Expect

  1. Pre-Procedure Preparation: Patients should avoid applying lotions or creams on the day of the procedure and may need to stop certain medications.
  2. Procedure: A small needle electrode is inserted into the muscle, and patients may be asked to contract the muscle to measure activity. The procedure typically lasts 30-60 minutes.
  3. Post-Procedure Care: Patients may experience mild discomfort or soreness at the needle insertion sites, which usually resolves within a few hours.

Benefits

  • Provides accurate diagnosis of nerve and muscle conditions
  • Helps guide further treatment options
  • Minimally invasive procedure
  • Quick recovery time

Risks and Side Effects

Though generally safe, some possible risks include:

  • Temporary soreness
  • Minor bleeding
  • Infection (rare)
  • Nerve irritation (very rare)
