Nerve Conduction Velocity and Electromyography (or NCV/EMG) is a testing procedure used to measure function of the nerves and muscles. This measurement assists in the diagnosis and treatment of numerous medical conditions including spinal disc bulges or herniation. Symptoms which suggest a need for NCV/EMG testing include tingling, numbness, or burning sensation of the legs or arms and pinched nerves.
Nerve testing evaluates the electrical conductivity of the motor and sensory nerves. A low electrical conductivity speed may be an indicator of nerve disease. NCV also detects damage of the nervous system, including the nerves leading from the brain to the spine and those that are branching out from the spinal nerves. Carpal tunnel syndrome, Guillain-Barre syndrome, or neuropathy can be diagnosed through the used of an NCV test.
Electromyography (EMG) refers to the technique of recording and analyzing the electrical activity of the skeletal muscles. EMG testing detects disease of the nerves or muscle tissue. An EMG may uncover issues such as disc herniation and reveal the cause of weakness, paralysis, or twitching of the muscle.
EMC/NCV testing done at our office is a minimally invasive procedure. EMC tests involve ultra-thin needles briefly places into various muscle locations to record measurements. NCV testing applies a low voltage electrical pulsation, administered to the surface of the skin in short durations.
