Electrodiagnostic Q & A

What is electrodiagnostic medicine?

Electrodiagnostic medicine is an approach to diagnosis, evaluation, and treatment of patients who have impairments in neurologic, muscular, and neuromuscular body systems.

Electrodiagnostic testing is a method of measuring electrical responses in the body to determine if there are any abnormalities. 

During normal functioning, your nerves send signals to your muscles telling them what to do. If you’re experiencing a problem with normal functioning it could mean those signals are either not getting through, or aren’t resulting in the expected response.

Electrodiagnostic testing can isolate any nerves that aren’t transmitting or receiving signals as they should to enable accurate diagnosis of your condition and facilitate appropriate treatment.

Electrodiagnostic medicine consists of two key tests:

Electromyogram (EMG)

Dr. Tabibian measures electrical signals using needles inserted into specific muscles that then creates a readout on the EMG machine.

Nerve conduction velocity (NCV)

Dr. Tabibian applies carefully calibrated electrical current to specific nerves to measure the speed and efficiency of nerve function.

Dr. Tabibian has undergone specialist training in electrodiagnostic medicine techniques so that he can interpret the data accurately. During the procedure, Dr. Tabibian inserts electrode needles into your skin or fixes electrode patches at strategic points to record nerve activity.

You may need to flex certain muscles and move in specific ways during the exam so Dr. Tabibian can measure the nerve responses in the affected area. The procedure takes between 20 and 60 minutes and should cause little if any discomfort.

What do the results of electrodiagnostic medicine tests show?

An experienced physician like Dr. Tabibian can use the information from your test results to assess whether you have any nerve damage or functional impairment and help diagnose the cause of symptoms such as:

  • Numbness
  • Pain
  • Weakness
  • Tingling
  • Pins and needles
  • Loss of mobility
  • Reduction of function
  • Lower back pain
  • Neck pain
  • Limb trauma
  • Paralysis
  • Spasms

The electrodiagnostic medicine tests highlight areas where nerves aren’t functioning as they should, which helps Dr. Tabibian identify the cause of your condition.

What conditions can electrodiagnostic tests diagnose?

Dr. Tabibian uses electrodiagnostic tests for the most accurate diagnoses. These tests can determine if you have conditions such as:

  • Carpal tunnel syndrome
  • Cubital tunnel syndrome
  • Cervical Radiculopathy
  • Sciatica
  • Nerve complications
  • Peripheral neuropathy
  • Pinched nerves
  • Amyotrophic lateral sclerosis (ALS)
  • Myasthenia Gravis
