Abstract
ObjectivesDiabetes can lead to loss of protective sensation (LOPS) in the feet. Identifying LOPS requires use of screening tests, such as the standard monofilament test (SMT) and the Ipswich Touch Test (IpTT). The aim of this validation study was to compare the SMT (criterion) with the IpTT (new test). MethodsEach participant was randomly tested using the SMT, IpTT and Neuropathy Disability Score to identify LOPS. Sixteen health-care providers assessed 8 participants in randomized order using a specific protocol. ResultsThe IpTT, compared with the SMT, demonstrated a specificity of 100% for all raters and a mean sensitivity of 93.8% for LOPS. Kappa coefficient was 0.97 for SMT and 0.83 for IpTT. ConclusionsThe IpTT can be used by health-care providers as an effective tool for screening for LOPS in people with diabetes. This study validated the IpTT to the SMT in identifying LOPS.
