Diabetes 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).
Each 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.
The 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.
The 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.
糖尿病可导致足部保护性感觉丧失（LOPS）。识别LOPS需要使用筛查测试，如标准单丝测试（SMT）和伊普斯威奇触觉测试（IpTT）。这项验证研究的目的是将SMT（标准测试）与IpTT（新测试）进行比较。
使用SMT、IpTT和神经病变残疾评分对每位参与者进行随机测试，以识别LOPS。16名医疗保健提供者按照特定方案对8名参与者进行随机顺序评估。
与SMT相比，IpTT对所有评估者的特异性为100%，对LOPS的平均敏感性为93.8%。SMT的kappa系数为0.97，IpTT的kappa系数为0.83。
医疗保健提供者可将IpTT用作筛查糖尿病患者LOPS的有效工具。本研究验证了IpTT在识别LOPS方面相对于SMT的有效性。
