Electromyography (EMG)

During electromyography examinations, a needle is inserted into a muscle. The electrical potential generated by the muscle is then measured during different conditions (at rest, slight contraction, maximum contraction). Electromyography makes nuanced diagnoses about muscular diseases (so-called myopathy) possible. Because the production of an electric potential with a muscle depends on the nerve supply, we can also examine disorders of nerves and nerve roots by carrying out electromyography examinations.
