INTRODUCTION Forearm QSWEAT recordings are occasionally absent in females, likely due to high skin resistance. METHODS We identified consecutive subjects with no sudomotor abnormalities but absent/markedly reduced QSWEAT forearm volume, and repeated QSWEAT at the same site after gentle abrasion. RESULTS QSWEAT volumes were absent for 4 subjects and markedly reduced for the other 4 (median 0.01, IQR 0-0.03). After gentle skin abrasion, repeat volumes were significantly higher for all subjects and became normal in 7 of 8 subjects. DISCUSSION Skin abrasion restores QSWEAT volumes in previously absent/markedly reduced site suggesting that skin preparation using abrasion is more effective.

消除 QSWEAT 记录中虚假的无汗反应

前臂 QSWEAT 记录偶尔在女性中不存在，可能是由于皮肤抵抗力高。方法我们确定了连续的受试者没有催汗异常但前臂体积不存在/显着减少，并在轻轻擦伤后在同一部位重复 QSWEAT。结果 4 名受试者没有 QSWEAT 体积，其他 4 名受试者明显减少（中位数 0.01，IQR 0-0.03）。轻轻擦伤皮肤后，所有受试者的重复量显着增加，8 名受试者中有 7 名恢复正常。讨论 皮肤擦伤可恢复先前不存在/明显减少的部位的 QSWEAT 体积，这表明使用擦伤的皮肤准备更有效。
