Nerve Conduction Testing

Nerve conduction studies measure how well and how fast the nerves can conduct electrical signals. An electromyogram (EMG) measures the electrical activity of muscles at rest and during contraction. 
Nerves control the muscles in the body with electrical signals called impulses. These impulses make the muscles react in specific ways. Nerve and muscle problems cause the muscles to react in abnormal ways.


If you have pain, numbness, or tingling in your arms, hands, legs, or feet, you may have these tests to find out if your nerves are being affected and how much.

These tests check how well your spinal nerves and the nerves in your arms and legs are working.
Some common causes to these nerve problems may include carpal tunnel syndrome or other nerve entrapments or pinched nerves, diabetic neuropathy, and radiculopathy (nerves pinched in neck or back).
