EMG

administering a little shock
An electromyogram (EMG) measures the electrical activity of muscles when they’re at rest and when they’re being used. Nerve conduction studies measure how well and how fast the nerves can send electrical signals.Once upon a time I worked in health care. Tests like these are hard for those who administer them. People get into health care to make people feel better. So studies that are unpleasant for the patient are not much fun to administer.
