应用 5 .0 7/ 1 0 g Semmes- Weinstein Monofilament(单丝 )随机检测 1 32例糖尿病患者右足 5个部位的感觉 ,结合足部震颤阈值分析研究每个部位对单丝的敏感性和特异性。同时应用弯曲力分别为 5 g和 1 5 g的单丝随机对 2 0 0例糖尿病患者右足 5个部位进行检测。结果 :患者无感觉足 (震颤觉阈值 >40 )的 5个部位对 5 .0 7/1 0 g单丝具有很高的特异性 (90 % ) ,但敏感性低而且十分易变 (40 %～ 70 % ) ,不同部位组合检测显示出过于严格的标准即低敏感性但高特异性的结合。另外弯曲力不同的单丝可造成检测结果的混乱。提示 :校正准确的单丝对足部跖侧第 1跖骨和第 5跖骨处皮肤的组合检测能很快得到合理可信的敏感性和特异性 (80 %和 86 % ) ,如果两个部位之一 ,对单丝的检测无感觉 ,可判定为无感觉足 Sensitivity and specificity of each site to monofilaments were studied in combination with the sensory evaluation of 5 sites on the right foot of 1 32 diabetic patients using a Semmes- Weinstein Monofilament (monofilament) . At the same time, monofilaments with bending forces of 5 g and 15 g were randomly selected to detect 5 sites of right foot in 200 diabetics. Results: Five sites in the patient without sensory foot (threshold for tremor threshold> 40) were highly specific (90%) to 5.07 / 1 0 g monofilaments but low sensitivity and very variable (40% ~ 70%), the combination of different parts of the test showed too strict criteria that low sensitivity but high specificity of the combination. In addition, different monofilament bending force can cause confusion in the test results. Hint: The combination of correct monofilament detection on the plantar first metatarsal and fifth metatarsal skin can quickly and reliably detect sensitivities and specificities (80% and 86%) if both sites First, the detection of monofilament no feeling, can be judged as no sense enough
