The role of electronic devices in the diagnosis of TMD raises the critical question of whether the clinician can gain diagnostically relevant information from them. This is of serious concern in view of the sparse, unreplicated and invalidated scientific evidence linking the use of such devices to TMD diagnosis and subsequent therapy. Until such time as scientific studies, using blinded evaluations to compare TMD patients and controls, demonstrate acceptable levels of reliability, validity, sensitivity and specificity, as well as positive and negative predictive values, the use of such devices will continue to have questionable diagnostic validity and, therefore, will continue to be considered experimental. Thus, clinicians should carefully consider the diagnostic and therapeutic consequences of using electronic devices prior to adding them to their dental armamentarium.

High blood pressure in medical electronics
MINNEAPOLIS — The medical electronics sector is under pressure to prove its value in the debate over the high costs of health care—some of the costs driven by expensive diagnostic systems. Many believe the sector's biggest contribution could be developing devices and networks that drive a shift to lower cost care at home, but market hurdles have stymied early efforts. "We all have a responsibility to be involved in health care reform," said Rebecca Bergman, a vice president of new therapies at Medtronic (Minneapolis), a leading maker of implantable devices. "Tech is not at the core of this issue, but we should make tech part of the solution and not part of the problem--that's the attitude we need to have," she said in a talk at the recent conference of the IEEE Engineering in Medicine and Biology Society (EMBC '09) here.
