Electrodiagnostic Testing

We now offer state of the art electrodiagnostic testing to assess nerve and muscle function. These testing procedures help to accurately diagnose and pinpoint problems related to nerves, muscles, the spinal cord and brain. Just as an MRI or CT scan can reveal a very detailed picture of a structural problem, electrodiagnostic testing reveals precise information about nerve and muscle function. A more accurate diagnosis allows for the best treatment.

Electromyography (EMG)

EMGs are used to record the electrical activity of muscles. Testing reveals a waveform that can be seen and heard for analysis. Waveforms produced by healthy muscle look and sound different from muscle that is damaged or undergoing atrophy. Needle EMGs are often performed when patients have unexplained muscle weakness and can help distinguish weakness due to a muscle problem or weakness due to a nerve disorder. It is often used to identify the severity of an injury and aid in developing a prognosis.

Needle EMG testing is the “gold standard” for assessing nerve and muscle function. While the testing may produce some brief discomfort, it is generally very well tolerated by most patients.

Nerve Conduction Velocity (NCV)

NVC studies measure the speed and intensity of electrical signals that travel through nerves, and calculates the time and velocity in which muscles respond to these impulses. It is often used to identify the location of nerve damage and to assess the severity of the problem. For example, a nerve might become entraped at the neck, elbow or wrist. In each instance the symptoms felt by the patient might be similar, but it would not be wise to have wrist surgery when the problem is actually at the elbow!

NCV/EMG testing allows for an accurate diagnosis of:

  • Carpal Tunnel Syndrome
  • Disc herniation
  • Sciatica
  • Numbness / Tingling
  • Arm and Leg Pain
  • Muscle Weakness
  • Diabetic neuropathy
  • Burning foot pain
  • Pinched nerves
