St. Mary's Neurology Associates
Neurology Associates provides Electrodiagnostic Medicine?
An EMG (electromyogram) records and analyzes the electrical activity in your muscles. It is used to learn more about the functioning of the nerves in the arms and legs.
During an EMG, Dr. Carl Robinson places a small, thin needle into different muscles to record the electrical activity. He will test only the muscles necessary to decide what is wrong. A new needle is used for each patient and it is thrown away after the test. Each time the needle is inserted, you may feel some pain or discomfort. Your electrical signals will then be recorded. After the needles are removed, you may experience some soreness and bruising, but this will disappear in a few days or less. There are no long-term side effects.
Nerve conduction studies are typically done along with an EMG (electromyogram) to determine if the nerves are functioning normally. Dr. Robinson tapes wires (electrodes) to the skin in various places along the nerve pathways. Then he stimulates the nerve with an electric current. Although you may initially be startled by the suddenness of the stimulation, it is generally not considered painful and most people are comfortable during the testing procedure. The shock is somewhat similar to one received when you touch a doorknob after walking across carpeting. As the current travels down the nerve pathway, the electrodes capture the signal and time how fast the signal is traveling. By stimulating the nerves at various places, Dr. Robinson can determine the specific site of injury. Nerve conduction studies also may be used during treatment to test the progress being made.
Generally, these tests can accurately determine injuries to the nerves or nerve roots as well as diseases of the nerves and muscles. The EMG procedure itself is not expected to improve your symptoms; it is used as a diagnostic test to help diagnose and further treat you.
To prepare for the test:
· You can do any of your normal activities, like eating, driving, and exercising, before the test
· Take a bath or shower to remove oil from your skin
· Do not use body lotion on the day of the test
· On the day of the test, tell Dr. Robinson if you have a pacemaker, or if you are taking blood-thinning medications such as aspirin, Plavix, Aggrenox, Coumadin, Pradaxa, Eliquis, or Xarelto
· The test itself usually takes 20-40 minutes
· You can do your normal activities, including driving, after the test
After the test has been completed, Dr. Robinson will analyze the results. Typically within 24-48 hours, a report is generated and sent to the health care provider that ordered the test. Please check with the provider who ordered the test to obtain results and plan the next step in your care.
Dr. Carl Robinson is located at 99 Campus Avenue, Suite 402, in Lewiston.
His office number is 207-777-4455.
