NC-stat Biosensors

NeuroMetrix’s patented, single use biosensor eliminates one of the most time-consuming and error-prone steps in nerve conduction studies – proper placement of electrodes on the patient. Using simple to find anatomical landmarks, the biosensor is accurately applied. Each biosensor is uniquely engineered for the specific nerve tested and connects easily to the NC-stat monitor. Currently, biosensors are available for the median, ulnar, peroneal, tibial, and sural nerves.

A biosensor is a preconfigured array of electrodes, eliminating the need for multiple placement sites and precise measurements. The NC-stat biosensor integrates flexible circuitry and a proprietary electrochemical gel with sensing electrodes. An embedded chip monitors skin surface temperature, an important covariate for nerve conduction studies. A unique serial number is also embedded in the chip to conveniently link patients to their test results.

Available biosensor types:

Lower Extremity Biosensors		Upper Extremity Biosensors
Peroneal		Median Motor/Sensory
Tibial		Ulnar Motor/Sensory
Sural		Ulnar Neuropathy at Elbow

The specific biosensors used in a particular patient study should always be determined by the physician ordering and interpreting the diagnostic information. Useful guidelines include Medicare local medical review policies (LMRP) and American Association of Neuromuscular & Electrodiagnostic Medicine (AANEM) position statements. As an aid to the physician, NEUROMetrix offers an NC-stat Testing Order Form that faciliates clinically appropriate nerve conduction testing.
