Mobile Diagnostic Services

Edge Diagnostics contracts with your clinic or comes straight to the patient to provide both Nerve Conduction Studies (NCS) and needle electromyography (EMG) in-house.

Timely Final Reports

​

With accurate and reliable data, the final report provides the information you need to make informed and dependable decisions to render optimal patient care. We perform the testing and deliver the finalized report within 48 hours of the test.

What is a EMG/NCS?

​

EMG/NCS testing consists of two distinct tests that evaluate nerve and muscle health.

​

The first test, a Nerve Conduction Study (NCS) evaluates the nerve health. Mild electrical stimulation is administered to the skin directly over the affected nerve. The nerve response is then measured by electrodes applied to the skin surface, which produces a visual signal that can provide information about the condition of the nerve.

​

During an Electromyogram (EMG), a small pin is inserted in the muscle to evaluate its condition by measuring electrical activity while the muscle is at rest and during contraction.

​

Who To Refer

​

In general, patients complaining of numbness, tingling, radiating pain and weakness with symptom duration of 21 days or longer are appropriate for referral.

 

Additional diagnoses that may benefit from referral for EMG/NCS are found HERE.

How To Prepare For The Test:

​

  • Clean Skin: No lotions or creams, oils, perfumes, or Vaseline anywhere on the body the day of the test.

  • Wear loose clothing: Providers need easy access to arms, legs, neck and back.

  • Be sure skin is cleaned thoroughly prior to the test.

  • Medications – Please bring a list of your current medications

  • All other medications may be taken as prescribed.

  • EMG/NCS will not affect pacemakers and defibrillators.

  • EMG/NCS does NOT require fasting. A normal meal schedule may be followed on the day of the test.

​Can Physical Therapists Perform The Test?

​

  • Physical therapists who provide electrodiagnostic testing services are required to complete a rigorous didactic curriculum, 500 clinical studies and 2000 hours of testing in order to qualify to sit for an examination administered by the National Board of Medical Examiners (NBME).

​

  • Currently, among all physical therapists in the United States, there are less than 200 who are board certified to provide electrodiagnostic testing services.
