Electrodiagnostic studies (EMG/NCS)
Electrodiagnostic studies are conducted on patients dealing with carpal tunnel, muscular diseases, or pinched nerves coming from the neck or lower back. Electrodiagnostic studies consist of two parts:
Part One: Small shocks of electricity are applied to the nerve, which allows your physician to view and record nerve functionality.
Part Two: A small needle electrode is gently inserted into the muscle, which helps evaluate the interaction between the nerve and the muscle.
