The VibroSense Meter records Vibration Perception Thresholds (VPT) at different frequencies with an automatic comparison with an aged dependent normal population. The age reference comparison is very important since the touch (as the hearing) is diminished at increasing age.

The measurement principle is very similar to a hearing test (Audiometry), but instead of utilising sound, the VibroSense Meter uses mechanical vibrations.The patient puts the investigated finger on a small "vibrating probe" that vibrates with different intensities and frequencies. In the free hand, the patient holds a button which shall be pressed (and held down) as long as the patient perceive a vibration in the finger. It is a fast test (takes about 3-4 minutes per finger) and easy to perform.

The result is presented as a Vibrogram curve, showing if the sense is normal or if there are any sign of incipient damage. The curve for each frequency in the vibrogram looks like a zigzag pattern and the Vibro Perception Threshold is calculated as the mean value of the peaks and bottoms of the curve. The Psychophysical algorithm corresponds to a modified von Békésy up/down algorithm.

A comprehensive test with the VibroSense Meter includes multi-frequency vibrametry of two fingers on each hand and a questionnaire, which is integrated in the PC program. The VibroSense Meter can also be used for Screening - which uses a faster variant of the method.

Research at the University hospitals of Lund and Malmö (Professor Göran Lundborg et al.) has shown that the VibroSense Meter can detect changes earlier than other methods. Early detection increases the chance to avoid a permanent injury.
