According to research papers I've read , and common sense. The site of the foot tested with a neurothesiometer is the apex of the hallux.
Although I have come across specialist podiatrists, that test the medial 1st MPJ, and the lateral malleolus.
What is the concensus out there in podiatry cyber space?

 

I have been using Xilas VPT meter for about 7 years. I use the same sites that I use the monofilament on. Sometimes the readings can be quite varied , but I take note of readings mostly over 25 volts.

I use it on every new pt. Most of the 70 - 90 year old also have high vibration thresholds and all of this group admit to very poor balance. I use this finding as a teaching moment to get these individuals out of the habit of slippers and into more supportive footwear in accordance with research that associates more falls with slippers.

Of course we are testing all of the people with a DX of DM. I lke using 4-5 sites as it gives me an average, shows up a few anomolies and is so fast to do. Dr Aaron Vinik lectures have me convinced that if we are about prevention; to find someone in the earliest stages of neuropathy, when there is some evidence to suggest it can be reversed is important. Once the numbers get high and there is a loss of protective sensation to feel a 10 gm MF, its a bit late and it becomes management.

I agree. I test the exact same sites as I would a mono-filament test.
Including the Malleoli.
