This is called nerve conduction studies (NCS). EMG signals are also used as a control signal for prosthetic devices such as prosthetic hands, arms and lower limbsĪn acceleromyograph may be used for neuromuscular monitoring in general anesthesia with neuromuscular-blocking drugs, in order to avoid postoperative residual curarization (PORC).Įxcept in the case of some purely primary myopathic conditions EMG is usually performed with another electrodiagnostic medicine test that measures the conducting function of nerves. EMG signals are sometimes used to guide botulinum toxin or phenol injections into muscles.
EMG is used as a diagnostics tool for identifying neuromuscular diseases, or as a research tool for studying kinesiology, and disorders of motor control. Medical usesĮMG testing has a variety of clinical and biomedical applications. The signals can be analyzed to detect medical abnormalities, activation level, or recruitment order, or to analyze the biomechanics of human or animal movement. An electromyograph detects the electric potential generated by muscle cells when these cells are electrically or neurologically activated. Electromyography (EMG) is an electrodiagnostic medicine technique for evaluating and recording the electrical activity produced by skeletal muscles. EMG is performed using an instrument called an electromyograph to produce a record called an electromyogram.
