To establish the validity of bedside sudomotor tests in a controlled prospective study.
Five different tests were used to assess presence of sweating at seven bilaterally symmetrical body loci, namely, examination with the unaided eye, visualization with light reflection, magnification with an ophthalmoscope, palpation of skin for slickness, and gliding the back of a spoon over the skin to detect friction. Sensitivity and specificity of these bedside tests were compared with the thermoregulatory sweat test in 130 subjects with generalized body sweating and 16 patients with complete anhidrosis.
The spoon test was more sensitive in detecting sweating than the other four bedside tests, demonstrating sensitivity of about 86% at the neck, 58% at the chest, and 51% at the forehead. Specificity of the spoon test was almost 100% at all body sites except at the chest (81%) and the neck (50%).
With caveats related to methodology, the spoon test is a clinically practical and useful bedside screening test for the assessment of sweating, especially at the forehead and chest.
在一项对照前瞻性研究中确定床旁汗腺功能测试的有效性。
使用五种不同的测试方法评估七个双侧对称身体部位的出汗情况，即肉眼检查、光反射可视化、用检眼镜放大观察、触摸皮肤是否光滑以及用勺背在皮肤上滑动以检测摩擦力。将这些床旁测试的敏感性和特异性与130名全身出汗的受试者和16名完全无汗患者的体温调节汗液测试进行比较。
勺背滑动测试在检测出汗方面比其他四种床旁测试更敏感，在颈部的敏感性约为86%，胸部为58%，前额为51%。除胸部（81%）和颈部（50%）外，勺背滑动测试在所有身体部位的特异性几乎为100%。
尽管存在与方法相关的注意事项，但勺背滑动测试是一种临床实用且有用的床旁筛查测试，用于评估出汗情况，尤其是在前额和胸部。
