EMG

Electromyography (EMG) is a technique for evaluating and recording the activation signal of muscles. EMG is performed using an instrument called an electromyograph (these days it's basically a high tech PC laptop!), to produce a record called an electromyogram. An electromyograph detects the electrical potential generated by muscle cells when these cells contract, and also when the cells are at rest. The nerves are also tested during the portion called nerve conduction velocity (NCV). This part of the test evaluates the integrity and health of the nerves.

Dr. Geraci uses the information from this type of testing to determine the nature of the nerve or muscle disorder you may have, or to verify findings on tests such as an MRI of the spine or brain.
