 EMG/NCS Testing
What is a EMG/NCS

Direct Performance is committed to objectively identifying the root of your problem towards treating you in the most efficient way. We are proud to offer EMG and Nerve Conduction testing (EMG/NCS) to identify the real cause of your pain conditions and find the best possible solution. The results of EMG/NCS testing can be an invaluable tool for your providers to determine various conditions that can affect your nerves and muscles.

If you are a referring provider, simply fax your EMG order to us at 1-757-585-3787 and we will get your patients scheduled ASAP! Reports are provided within 2 business days of the patient's appointment. 

Who needs EMG/NCS testing? Most commonly, patients are referred for problems that involve pain, weakness, numbness, or tingling in the limbs, neck, or back. Our physical therapist will provide an EMG report that describes the condition of the peripheral nervous system to assist the referring provider in their diagnosis. 

EMG/NCS testing is reliable and safe! We use latest generation electrodiagnostic equipment and disposable electrodes to collect the most accurate data. 


Physician Testimonials 

“Aaron, thank you for providing great EMG/NCS services to our patients. They report to me that you are kind and made them feel at ease. I am very impressed at the quality of your reports and assessments. Once again thank you for providing great medical care.”

What is Nerve Testing(EMG/NCS)

Nerve Testing (EMG/NCS)

EMG stands for Electromyography and NCS stands for Nerve Conduction Studies. The EMG & NCS tests are performed during that same visit: 

1. Nerve Conduction Studies (NCS) are used to measure the health of your nerves. Mild electrical stimulation is administered to the skin directly overlaying the nerve. The response is measured by a second set of electrodes applied to the surface of the skin. This impulse produces a visual signal on a computer monitor and when analyzed it can provide information about the condition of the nerve.
2. An Electromyogram (EMG) measures the electrical activity of muscles at rest and during contraction. Nerves control the muscles in the body by electrical signals (impulses), and these impulses cause the muscles to react in specific ways. Nerve and muscle disorders cause the muscles to react in abnormal ways. During an Electromyography study, a very small needle is inserted in the muscle that helps us evaluate the condition of your muscles.

Measuring the electrical activity in muscles and nerves can help find diseases that damage muscle tissue (such as myopathy and muscular dystrophy) or nerves (such as amyotrophic lateral sclerosis or peripheral neuropathies).
