Diagnosis of diabetic neuropathy using the Neurothesiometer

This educational video shows you how to perform vibration perception threshold, VPT, testing.


VPT testing identifies peripheral nerve dysfunction in a quantifiable manner, staging the severity of peripheral neuropathy. The VPT is tested on the pulp of the large toe. The test needs to be repeated three times and the average value is recorded. The VPT score for normal, mild, moderate and severe sensory loss is 0-14 V, 15-24 V, 25-35 V and higher than 35 V, respectively.
