The VSA-3000 Vibratory Sensory Analyzer is a computerized device offering quantitative assessment of the function of large-caliber, A-beta sensory nerve fibers of the peripheral nervous system. Available as a stand-alone unit or as an accessory option to the TSA-II NeuroSensory Analyzer, the VSA-3000 quantifies vibratory sensory perception thresholds and is a clinically validated method of rapid screening, early detection and longitudinal evaluation of those at risk of sensory dysfunction associated with disease and occupational injury. Common applications include evaluation of diabetic neuropathy, carpal tunnel syndrome, lumbar radiculopathies and various peripheral and compression neuropathies.

Principle of Operation
The VSA-3000 is comprised of a Hand and Foot Support Vibratory Stimulators, Operating Software and Accessories. The Vibratory Stimulator is built into an ergonomically designed, comfortable and easy to use platform which functions as a hand support with the stimulator head facing up. The vertically facing stimulator head creates a controlled pressure of 50 grams against the test site, providing a means of assessing the underside of the hand, i.e. pulp of the finger. A Foot Support accessory supports the foot for evaluation of the foot/plantar. It has been demonstrated that testing of the pulp in this manner has been shown to provide more reliable and reproducible results, while optimizing patient comfort and thus compliance. An optional Hand-held Vibratory Stimulator, with 1.5 meter cable for testing of trunk, face and other body sites, offers flexibility and easy access to variety of sites on the patient's body.
