Nerve Conduction Study & EMG Q & A

What is a nerve conduction study?

A nerve conduction study (NCS) measures the velocity (speed) at which your nerve signals (electrical impulses) travel through the affected nerve. A nerve conduction study can indicate nerve damage if the nerve signals move abnormally slow or fast.

What is an EMG?

An EMG, or electromyography, helps diagnose neuromuscular conditions. Nerve signals from your brain tell your muscles when to move and contract. By measuring the electrical activity in your nerves when stimulating the affected muscle, an EMG can detect neuromuscular disorders and nerve injuries.

Do I need a nerve conduction study or an EMG?

Your Healthcare Pain Centers LLC provider may recommend a nerve conduction study and EMG test to uncover the root cause of unexplained pain or soreness. In most cases, they perform a nerve conduction study and EMG at the same appointment. 

Both tests can reveal critical information about your nerve function if you’re experiencing:

  • Shock-like pain
  • Numbness
  • Tingling
  • Weakness
  • Muscle soreness

These tests can help your provider diagnose neuromuscular conditions that include:

Carpal tunnel syndrome

The carpal tunnel is the passageway in your wrist that houses the median nerve. Compression of the median nerve inside this narrow tunnel can lead to wrist and hand pain, numbness, weakness, and tingling.

Herniated disc

The discs that cushion the vertebrae in your spine consist of an outer shell and jelly-like center. When cracks form in the outer shell, the soft center can push through, herniate, and irritate your surrounding nerves.


The sciatic nerve stretches from your lower back down the back of your hips, buttocks, and thighs. Compression of this nerve from a herniated disc, injury, or fracture can cause chronic pain and discomfort.

What happens during a nerve conduction study and EMG?

Dr. del Valle is a trained physical medicine and rehabilitation (PM&R) doctor with additional training in electrodiagnostic medicine. He performs both tests from the comfort of his Old Bridge office.

Nerve conduction study

During a nerve conduction study, your doctor places electrode patches on your skin and sends electrical impulses to the affected nerve.


An EMG test is similar to a nerve conduction study, but the electrodes contain tiny needles to evaluate your neuromuscular function. After placing the electrode patches, your doctor may ask you to contract or relax certain muscles to complete the study.
