Vibratory Perception Threshold Analysis System

Vibratory Perception Threshold Analysis System is applicable for both standalone and PC based mode performance. VPT Analysis System’s vibratory perception threshold quantifies the loss of sensation in patient’s feet. This system is widely used in hospitals. Apparently, our company has carved a niche for itself as one of the foremost Thesiowin Exporters.

Loss of sensation due to neuropathy is the major cause of painless injuries to the feet. Such injuries result into chronic ulcerations and further complications leading to large amputations. Hence early and accurate detection of sensation loss due to neuropathy is the best way to protect the feet from amputation. Also, it is very important to quantify sensation loss risk to monitor the trend by follow-up.

ThesioWin serves in both ways. The vibratory perception threshold at various sites on plantar foot quantifies the loss of sensation. Increase in VPT means diminished sensation and increasing risk. ThesioWin when used in PC based mode, a tabular trend of VPT is available. ThesioWin being digital, gives very accurate readings. With a sophisticated vibration mechanism, it virtually eliminates the possibility of pressure dependency of VPT. It has an intuitive Reading site locator. It also has a 12 readings memory in the H/w unit.

Windows* based ThesioWin software & serial port communication with the ThesioWin instrument turns any PC into a full-fledged VPT analysis system, with online readings on screen. It gives a multicolor / B & W one-page report on A4 size paper. In-built patient database with more than 1000 patient’s memory helps you keep track of patient history. All at your mouse clicks in a very user-friendly ThesioWin software environment.
