Answer

One problem with electromyographic testing is that needles are used and the study may be painful; however, new computerized technology allows the use of recording needles so small that insertion feels more like a pinch than like the insertion of a needle. Small-gauge needles can be used, because nothing is injected or aspirated. Seek out electromyographers who have access to current technology and who have board certification, in order to ensure that patients do not suffer more discomfort than is necessary during a procedure.

A current worrisome trend is the performance of electromyographic testing by nonphysician health care personnel. The performance of electromyography and the interpretation of electromyograms require technical skill and the ability to integrate the physician's knowledge base of disease pathology with diagnostic acumen.
