 Electromyography and Nerve Conduction Studies are evaluation procedures to determine how nerves and muscles are functioning. Nerve conduction testing measures how fast a nerve can conduct an electrical stimulus. Measuring the nerve conduction velocity allows the clinician to determine whether a nerve problem exists and helps to establish what nerve segment is at fault. Electromyography or EMG testing determines how severe a nerve problem is by testing a sampling of muscles supplied by the nerve in question. This process involves placing a very thin needle electrode into a muscle and then listening to the muscle at rest and during contraction. EMG and nerve conduction testing provides objective measurements for problems such as carpal tunnel syndrome, cubital tunnel syndrome, tarsal tunnel syndrome, nerve root involvement, and many other muscle and nerve disorders.
