What is an Electromyography (EMG) Test?
An EMG study is a 30- to 60-minute diagnostic test that helps discover injuries, neuromuscular disorders, pinched nerves and muscle diseases. During the test, a physician uses small needles to measure how your muscles respond when you’re not using them (at rest) and when you tighten them (contraction). It allows the physician to evaluate how well muscles are working and can help determine if the muscles are receiving the proper signal from nerves.What is a Nerve Conduction Study?
This diagnostic test measures the speed of electrical activity in your nerves. The provider places electrode patches on your skin and stimulates them with small electric impulses to measure how fast or slow your nerves are functioning.Find an Electrodiagnostic Medicine Location

A Paralyzed Diaphragm Couldn’t Stop This Marathon Runner
“My paralyzed diaphragm went undiagnosed for years until I found Dr. Matthew Kaufman. My phrenic nerve surgery went great and I got really wonderful care. I still get calls from his team to check how I’m feeling. I’m so grateful for all of them.” — Adam Wernow, Long Island, N.Y.
