Understanding the Basics of Electromyography (EMG)

Doctors may recommend an EMG when patients present with symptoms that suggest a problem in the nerves or muscles. Some of the most common reasons for EMG testing include:

• Numbness or tingling in the arms, legs, hands, or feet
• Chronic pain that radiates from the spine into the limbs
• Unexplained muscle weakness or cramping
• Frequent muscle twitching or spasms
• Difficulty moving certain muscles

By identifying whether the issue originates in the nerves, the muscles, or the connection between them, an EMG can help narrow down a diagnosis and guide treatment planning.
