1. The study by microelectrode recording of the electrical activity of individual muscle fibers.
2. A test used to evaluate the activity of single fibers of selected muscles; for example, common extensor of fingers, displayed as an action potential on an cathode-ray oscilloscope; SF-EMG may detect early defects in neuromuscular junction diseases; such as, myasthenia gravis, Eaton-Lambert syndrome, or botulism.
