Electrodiagnostic Testing

There are many tools that orthopedic doctors use to diagnose and analyze a patient’s needs. One of those tools is known as electrodiagnostic testing, which includes electromyography (EMG) as well as nerve conduction studies (NCS). These tools have many benefits, but how accurate are they?

Electromyography (EMG) Tests

An EMG records and analyzes the electrical activity in your muscles. Small, thin needles are placed in the muscle to record the electrical activity as the patient relaxes and contracts the muscle. If you are experiencing different degrees of pain in your hands, neck, and back, an EMG will measure the electrical activity level in those areas to determine the type of treatment that is needed.

Nerve Conduction Studies (NCS)

NCS tests are usually done along with EMG tests to determine if a nerve is functioning normally. During this procedure, wires are taped on the skin surface along the nerve pathway. Electrical signals are sent along the pathway, and the sensors record the electric activity and measure how fast the impulse travels along the nerve pathway.

Electrodiagnostic testing can accurately diagnose the patient and have even been used in other areas of medicine such as diabetes treatment. While the tests do not determine the extent of pain, electrodiagnostic testing is a great tool for doctors when analyzing your orthopedic issues. Once you have undergone an electrodiagnostic test, results will take a few weeks before the doctor can diagnose properly.
