We first evaluated whether itch intensity was perceived differently at three body sites, and then we investigated the potential correlation between the pleasurability and the itch relief induced by scratching," he explained.
Itch intensity and scratching pleasurability were assessed every 30 seconds for a duration of five minutes using a Visual Analog Scale (VAS) to rate intensity - 0 for no itch, up to 10 for maximum unbearable itch.
Another major finding of the paper, as Yosipovitch explains, is that "the pleasurability of scratching the ankle appears to be longer lived compared to the other two sites.
On the broadest level, pleasurability was seldom a matter of serious dispute within an intellectual field, rooted in the kamasastra (Warder 1972-2004, vol.
