You undergo electromyography, or EMG, to diagnose issues pertaining to the health of muscles and motor neurons. Board-certified neurologist David Sudderth, MD, uses EMG results to assess nerve dysfunction, muscle dysfunction, or the signaling between the nerves and muscles. Men and women in Fort Myers, Florida, who are having symptoms of nerve or muscle dysfunction, should call the office or request a visit online to be evaluated by Dr. Sudderth today.
An EMG uses tiny devices, or electrodes, to translate signals into data that are then interpreted by Dr. Sudderth.
A needle electrode may be inserted directly into a muscle to record the electrical activity in that muscle. A nerve conduction study may involve the application of surface electrodes – stuck to your skin like stickers – to measure nerve signals traveling between two or more points.
Dr. Sudderth may recommend an EMG for the following symptoms:
Certain types of limb pain may warrant an EMG. Dr. Sudderth uses the screening to diagnose (or rule out) issues such as muscular dystrophy, carpal tunnel syndrome, peripheral neuropathy, polio, and other disorders of the brain and spinal cord. EMG can also evaluate herniated discs that affect the nerve root and cause pain and numbness.
An EMG carries little risk and is safe for most patients. Most people tolerate an EMG well and have no complaints, but you may feel some twinges as the surface electrodes transmit small currents to the area being screened. If your EMG involves needle electrodes, you may feel discomfort when the needles are applied, but the sensation resolves quickly when the tech removes the needles.
Dr. Sudderth may request you stop taking certain medications, both prescription and over-the-counter, before the EMG. Be sure to discuss these precautions with him.
You’ll want clean skin for the test, so bathe or shower just before but refrain from putting on any lotion or cream, which can make your skin slippery.
You may have some mild bruising at the sites where needle electrodes were applied. This bruising should fade within a few days. You shouldn’t need to take any time off of work or school following an EMG.
Following your EMG, Dr. Sudderth interprets the results and prepares a report. He’ll set up a separate appointment to discuss your results, diagnose any conditions, and propose possible treatment.
If you have unexplained muscle or nerve pain, an EMG can help. Schedule yours today by calling the office of Dr. Sudderth.
