In order to provide the best possible care to you, your doctor needs to determine the cause of your symptoms. The following symptoms warrant this diagnostic procedure:
Symptoms that you experience are your body’s way of telling you that something is wrong. There are numerous reasons that you may be experiencing these symptoms. An EMG study is an important test that will help your doctor to establish a proper diagnosis and will assist in setting a treatment plan tailored to target the cause of your symptoms.
The procedure is mildly uncomfortable; a small electric shock is applied to the nerves that are being tested. This sensation is very similar to the shock of static electricity, which we often experience on a hot dry day when we touch another person.
There are two parts to the test. In the first part, the technician will place sticky pads along specific sites of your arms or legs. A stimulator probe will be placed on top of your skin and mild electrical impulses will be sent up the nerve pathway. This electric impulse excites the nerve and an impulse then travels down the nerve to its muscle which it contracts. The technician will record the electrical activity of your nerves.
The second part of the test will be performed by a neurologist. This portion of the test is similar to the other portion; however a small needle is used by the neurologist. This part of the test provides important information about the muscles and how the muscle is communicating with your nerves. It will also help differentiate between a muscle disorder and a nerve disorder.
There is no risk or damage done to the nerves or body by this investigation. The human body actually produces its own natural electrical currents to deliver messages from the brain to the other parts of the body. These naturally occurring electric currents in your nerves can be affected by injury, inflammation, disease, and/or other conditions. You can continue your medications as usual, and you will be able to resume normal activities directly after testing.
