EMG stands for electromyogram, which is a diagnostic tool for detecting muscle and nerve disorders. The test measures electrical activity or impulses in the affected muscles and can reveal abnormal responses that might be indicative of a disease or disorder. Dr. Enrique Umpierre-Schuck, the board-certified medical provider at Central Florida Pain and Rehab Clinic in Winter Park, FL, performs EMG tests and treats nerve and muscle disorders.
What is an EMG
An EMG test is commonly performed when a patient shows signs of nerve damage or muscle disease. The test works by assessing muscle function and whether the muscle tissue is responding correctly to nerve signals. An EMG is performed by inserting thin needles directly into the affected muscle tissue. Attached to the needles are electrodes that send information to a monitor where muscle and nerve activity are recorded.
The results of the EMG assist doctors in accurately diagnosing the problem, such as muscle or nerve dysfunction, a neuromuscular disorder, muscle disease, or an injury to the muscles or nerves. Once the problem is diagnosed, a treatment plan can be developed. Some conditions that can be diagnosed based on EMG feedback include:
- Carpal tunnel syndrome
- Peripheral neuropathy
- Sciatica nerve dysfunction
- Radial nerve dysfunction
- Amyotrophic lateral sclerosis (ALS)
- Muscular dystrophy
Many patients who undergo EMG testing benefit from also having an NCS test, which stands for nerve conduction study. Performing both diagnostic tests provides more feedback regarding the location and extent of muscle or nerve damage. While an EMG measures electrical impulses of muscles, the NCS test measures how quickly and effectively electrical signals are sent by the nerves to the muscles. Dr. Umpierre can determine if you need both an EMG and NCS test.
Benefits of an EMG
There are several benefits to undergoing an EMG at our Winter Park, FL, clinic. If you are experiencing muscle pain, the test can reveal the exact nature of the problem so it can be properly treated. An EMG can also help doctors rule out certain diseases or disorders. An additional benefit of the test is that it is nonsurgical and only minimally invasive. Most patients tolerate the procedure without any problems beyond some temporary initial minor discomfort when the needles are first inserted in the muscle.
EMG tests help doctors diagnose specific muscle or nerve disorders that might be causing pain, discomfort, and other symptoms.
