Elektroneuromyography, often abbreviated as ENMG or ENG, is a diagnostic medical procedure used to assess the health and function of muscles and nerves. It combines two distinct tests: electroneurography (ENG) and electromyography (EMG). Electroneurography measures the speed and strength of electrical signals traveling along nerves. This is done by applying small electrical impulses to a nerve at one point and recording the response at another point with surface electrodes. The time it takes for the impulse to travel between the points helps determine the nerve's conduction velocity. Electromyography, on the other hand, evaluates the electrical activity within muscles. This involves inserting a very fine needle electrode directly into the muscle being tested. The electrode detects the electrical activity generated by muscle fibers when they contract and relax.

ENMG is a valuable tool for diagnosing a wide range of neurological conditions. It can help identify nerve damage, compression, or inflammation, such as in carpal tunnel syndrome, sciatica, or peripheral neuropathy. It is also used to diagnose muscle disorders like muscular dystrophy or myasthenia gravis, as well as diseases affecting the motor neurons, such as amyotrophic lateral sclerosis (ALS). The procedure is generally well-tolerated, although some discomfort may be experienced during needle insertion. The results of ENMG provide objective data that aids clinicians in pinpointing the location and severity of nerve or muscle dysfunction, guiding treatment decisions and prognosis.
