Measuring Vibration Perception to Detect Neuropathy
Biothesiometer
Biothesiometry is a non-invasive test that measures the vibration perception threshold (VPT) in humans. The VPT is the lowest level of vibration that a person can detect. A high VPT can indicate peripheral sensory neuropathy, a condition that damages the nerves in the feet and legs.
How is biothesiometry performed?
During a biothesiometry test, a physician will place a vibrating probe on the bottom of your foot. The probe will gradually increase in vibration until you can feel it. The physician will then record the VPT.

Peripheral sensory neuropathy is a common complication of diabetes. It can lead to foot ulcers and other problems that can require amputation. Biothesiometry can help to identify people at risk for neuropathy so that they can receive early treatment and prevention measures.
Why is biothesiometry important?
What do the results of a biothesiometry test mean?
A VPT of 10 volts or less is considered normal. A VPT of 11 to 25 volts may indicate mild neuropathy. A VPT of 26 to 50 volts may indicate moderate neuropathy. A VPT of over 50 volts may indicate severe neuropathy.
Who should get a biothesiometry test?
We recommend that all people with diabetes get a biothesiometry test at least once a year. People with other risk factors for neuropathy, such as smoking, high blood pressure, or high cholesterol, may also benefit from biothesiometry testing.
If you have a high VPT, what should you do?
If you have a high VPT, we will recommend lifestyle changes to improve your blood flow and circulation, such as quitting smoking, exercising regularly, and eating a healthy diet. We also prescribe medication to lower your blood pressure or cholesterol.
