Electromyography (EMG) is a study that evaluates the electrical activity in your muscles. At The Neurology Institute in Coral Springs and Sunrise, Florida, the team conveniently performs this important medical study on-site. This allows your provider to diagnose and treat your condition as quickly as possible. Don’t wait to get answers for your symptoms.

An EMG is a test to measure electrical signals in your muscles. The test evaluates electrical signals at rest, when you slightly contract the muscle, and when you forcefully contract the muscle. EMGs help diagnose neuromuscular abnormalities.
You usually have an EMG and nerve conduction study at the same time. The nerve conduction study measures the speed with which electrical impulses travel through your nerves and how effectively those signals move.
You could need an EMG and nerve conduction study if you’re having symptoms of muscle or nerve damage or disease. Symptoms that might indicate a problem include:
These symptoms could be a sign of disorders such as muscular dystrophy, myasthenia gravis, or amyotrophic lateral sclerosis (ALS). An EMG and nerve conduction study can help The Neurology Institute team diagnose your condition and rule out other issues.
Wear loose-fitting clothing to your EMG so you can easily expose the body part under study. Don’t apply any lotions, oils, or creams to your skin, as you need clean skin.
If you’re currently taking anticoagulant medications, let the team know ahead of time. While you don’t have to stop taking the medication, your provider needs to take extra precautions to ensure your safety.
In an EMG, a technician inserts a thin needle electrode into a muscle. With the needle inserted, you tighten and release the muscle as directed. The technician may move the needle to other muscles as well.
The electrode connects to a wire that relays your muscle electrical activity to the EMG machine. The activity appears as waves and spikes on a nearby screen. The test may record this activity for later evaluation.
If you have a nerve conduction study, the electrodes stimulate nerves to elicit a reaction. The test also measures how long it takes for the stimulated nerve to trigger a muscle contraction.
The EMG process usually takes 30 minutes or less. You can resume normal activities immediately afterward.
