A tiny needle electrode translates your nerve signals into graphs, sounds and numbers that are then interpreted by a specialist.Īnother part of an electromyography (EMG) test is a nerve conduction study, which measures the amount and speed of electrical activity through the nerve to determine nerve damage. What is an electromyography (EMG) test?Īn electromyography (EMG) test helps diagnose muscular and neurological conditions by recording electrical activity in affected areas of your body. If you’re experiencing these symptoms, your doctor may recommend nerve conduction studies including an electromyography (EMG) test. The result is muscle weakness, numbness, tingling, and in severe cases, difficulty moving the areas of the body where the nerves and muscles are damaged. If the nerves or muscles become damaged, communication can break down. When you want to move, your brain relays electrical signals to the muscles via the spinal cord and nerves, and those signals tell the muscles what to do.
Nerves and muscles work together within the neuromuscular system.
