Electromyography, or EMG, involves testing the electrical activity of nerves and muscles. We use this term to include both the needle test and the nerve conduction test. The EMG or needle test involves testing the electrical activity of the muscles. The nerve conduction study measures the electrical conduction of the nerves and aids and the diagnosis of peripheral nerve disorders.
Nerves work like electrical wires and carry electrical information to and from the brain. Stimulation of the nerves in the nerve conduction test will cause the muscles to contract. Measurement of these impulses will allow us to determine whether there is a problem with the nerves and muscles being tested. The needle test or EMG directly measures the electrical activity of the muscles. This reflects both the health of the muscles being tested and the nerves that are attached to those muscles.
EMG and nerve conduction studies may aid with the diagnosis of:
Dr. Leschek or Dwyer will share the results with you and answer any questions you may have. They will immediately share the results with your referring physician with whom you will be referred back to for any future work up or treatment as indicated.
