• Electrodiagnostic Studies(EDS)

    EDS include nerve conduction studies (NCS) and electromyography (EMG). This test is used to evaluate nerves and muscles in the diagnosis of compressive nerve injuries, neuromuscular disease, and myopathies. It is most often used to evaluate people who complain of numbness and/or tingling anywhere in the arms, hands, legs, or feet, or a sensation that one of these body parts feels like it “falls asleep”. EDS is also used to study nerves in people who have pain or odd sensations that travel down part of an arm or leg.

    There is a small amount of discomfort usually experienced while performing EDS. NCS involves using a nerve stimulator that delivers a mild shock to directly assess how fast nerves are conduction signals. EMG is performed with a small pin that is inserted into the muscle that records electrical muscle activity.

    If you are having this test done, you should wear or bring a short sleeved shirt if you are having symptoms in your neck, arms, or hands. Wear or bring a pair of shorts if symptoms are in your low back, legs, or feet. Your arms, hands, legs, and feet should be clean without any creams or lotions applied before having the test performed. After the test, it is normal to have a small amount of muscle soreness, if any at all.
