In 1942 a curve of skin conductibility to direct current was described in Prague. It is a slow or steep rising of intensity in the few seconds following the introduction of the 12 V current to the hand from the dorsum to the palm. This method has been called dermatophoria. This curve is characteristical for a given individual and it is different in paretic (central and peripheral) limbs, generally more flat. In children the curves are steeper. However, abnormally steep there are in 57% of juvenile vasomotor headaches. Dermatophoria is therefore promising to be an objective method in diagnosis of children's headache.
1942年,布拉格描述了皮肤对直流电的传导曲线。从手背向手掌引入12伏电流后的几秒钟内,强度会缓慢或急剧上升。这种方法被称为皮肤电反应。这条曲线对特定个体具有特征性,在麻痹(中枢性和周围性)肢体中有所不同,通常更平缓。在儿童中,曲线更陡峭。然而,在57%的青少年血管运动性头痛患者中曲线异常陡峭。因此,皮肤电反应有望成为诊断儿童头痛的一种客观方法。
