EMG / NCV
Here at Abundance Physical Therapy, we are proud to offer Electro Diagnostics (EDX) by utilizing EMG / NCV, also known as Electromyography / Nerve Conduction Velocity.
EMG / NCV is a diagnostic test, performed by a qualified provider, which is used to analyze muscle health and their corresponding nerve cells. An EMG / NCV can help determine if you have a muscle dysfunction, a nerve dysfunction, a pinched nerve, an irritated or bruised disc slowing a nerve, generally slowed nerve speeds, or other issues regarding the signal transmission between your muscles and nerves.
At Abundance Physical Therapy, our Savannah physical therapy practice is highly skilled and experienced in EMG / NCV. To find out more about EMG and how it may benefit you, contact Abundance Physical Therapy today.
What is EMG / NCV?
EMG (Electromyography) uses a small needle/pin electrode that is placed within the muscle to assess nerve and muscle function. During the EMG, we are listening to the electrical activity of the muscle, which corresponds to normal or injured nerves and muscle. The diagnostic equipment then converts these electronic signals into graphs, sounds, and numerical values, to determine any dysfunction that may have developed in the affected area.
NCV (Nerve Conduction Velocity) examines the health and speed of nerves that contract muscles and provide sensation to your skin. The NCV is done by measuring and then applying an electrical stimulation along these nerves to record the nerves ability to conduct electrical signals along their path and identify any areas of problem
While EMG / NCV is a diagnostic test, the test by itself does not provide a medical diagnosis. Your medical doctor may utilize the information along with other physical examination, imaging and diagnostic tests to provide you a medical diagnosis. By understanding any disorders of the nerves and muscles, our qualified providers will modify treatment plans and select appropriate physical therapy interventions lending to improved outcomes.
Why is EMG / NCV done?
The main reason why our Savannah physical therapists will decide to perform EMG / NCV is to examine a suspected disorder or dysfunction in either your muscles or nerves. This allows us to objectively assess which nerves are not healthy and which muscles are showing signs of problems. From there, we will know objectively what can be done and create a treatment that will get you the needed treatment, fast. Some signs that may indicate potential disorder or dysfunction include:
- Pain in the limbs
- Pain or cramping in the muscles
- Weakness in the muscles
There are a large number of conditions that EMG / NCV can help our Savannah physical therapists examine. These include, but are not limited to:
- Disorders that affect the nerve root, such as a herniated disc in the spine.
- Disorders of nerves outside the spinal cord (peripheral nerves), such as carpal tunnel syndrome or peripheral neuropathies.
- Muscle disorders, such as muscular dystrophy or polymyositis.
- Diseases affecting the connection between the nerve and the muscle, such as myasthenia gravis.
- Disorders that affect the motor neurons in the brain or spinal cord, such as amyotrophic lateral sclerosis or polio.
What can I expect from EMG / NCV?
A tiny electronic microphone, which will appear to be a pin/needle, is gently placed into the affected muscle. You may feel some slight discomfort, but it should not be painful. There may be some normal discomfort as the small microphone is removed, but that should disappear almost immediately. You may be asked to move the affected area in certain ways or contract the affected muscle, in order to determine which signals are being affected and where the areas of inactivity are present.
You may notice some discomfort with movement, but our physical therapist will not ask you to make any extreme movements to the muscle. You may also be asked to change positions in the way you are sitting or lying down during the testing.
If you notice some soreness from the movement following the EMG / NCV, it should go away shortly. Our physical therapist can also provide you with remedies you can do at home to ease any discomfort.
After your EMG / NCV is complete, our physical therapists will analyze the results. This analysis will take a short period of time, however by your next session your plan will be fully developed based upon the information gathered and your Physical Therapy Diagnosis will be provided. We will design a personalized treatment plan for your specific needs, in order to help relieve your pain and improve your condition.
