Electromyography, also known as EMG, is a diagnostic procedure that assesses the health of muscles and the motor neurons that cause them to contract via the transmission of electric signals. An EMG uses electrodes to detect these signals and translate them into graphs, sounds or numerical values. ​For the EMG a thin pin needle is inserted ​directly into a muscle, recording its electrical activity. For a nerve conduction study (NCS), electrodes are taped to the skin in order to measure the speed and strength of signals traveling between two or more points.

Why was ​an EMG Study ordered by my doctor?

Electromyography (EMG) and Nerve Conduction Studies (NCS) will help determine problems you may be having with muscle movement or diagnose nerve damage issues. Dr. Choi will then interpret the results, which can reveal nerve dysfunction, muscle dysfunction or problems with nerve-to-muscle signal transmission. ​​

​A number of conditions can be diagnosed or ruled out by an EMG, such as:

​•    Carpal tunnel syndrome
•    Lumbar/ Cervical Radiculopathy (Pinched Nerves)
•    Muscular dystrophy
•    Peripheral neuropathies
•    Amyotrophic lateral sclerosis (Lou Gehrig’s Disease)

​Symptoms that indicate the need for an EMG include tingling, numbness, muscle weakness, muscle pain, cramping and certain types of limb pain.
