An analog biothesiometer kitA digital biothesiometer
Biothesiometry is a noninvasivemedical test used to quantify the perception of vibration by measuring its threshold.[1] It is used in neurology and electrophysiology to diagnose a number of conditions, like diabetic neuropathy and erectile dysfunction, where the vibration perception threshold (VPT) would be higher than average.[1][2] The numerical nature of the test can help stage the progression of disease or complications.
The test is done through a biothesiometer, which is composed of a handheld probe wired to a display unit. Both digital and analog types are commercially available, giving the reading on either a dial or a screen.
A systematic review showed that there is a strong co-relation between HbA1c values and Vibration Perception Test and could be a predictor for complications in the foot following Diabetic Peripheral Neuropathy.[4]
In a systemic review of modern devices available for the assessment and screening of peripheral neuropathy, digital devices were evaluated to measure tactile sensation, vibration perception, thermal perception and foot skin temperature.[5]
