The Ipswich Touch Test (IpTT): Your Diagnostic tool is "at hand"

Pardon the pun from Ipswich’s own Gerry Rayman, but this simple, effective touch test to identify loss of protective sensation is, in our opinion, ready for prime time. See the manuscript here

  • the International working group on the Diabetic foot classify a person as having loss of sensation at just 1 o4 sites on a foot. Why does the IPTT than only classify loss of sensation at 2/6 sites? Potentially in comparison to the monofilament than the IPTT could produce a false negative where the monofilament would detect and classify a person as having LOPS with sensory loss at 1 site eg Large toe of 1 foot where as according to IPTT that same site that is insensitive would not be regarded as having LOPS. Therefore the IPTT in such cases is not as sensitive as 4 point monofilament testing as recommended by the IWGDF Please comment on this discrepancy


    • I would tend to agree with you, Yusuf, as our group were ones who performed the early accuracy/receiver operating characteristic curve analysis using SWMF/VPT/etc. However, works by Rayman and coworkers have suggested it to be substantively equivalent.
