Quick evaluation of light touch sensibility
Maximilian von Frey showed already 1896 that the threshold for touch evoked sensations in humans can be determined by sequentially applying hairs of different diameters until the hair that just creates the requested sensation is found. One hair can also be used for screening purposes, to find if that particular hair – with its buckling force – produces a particular sensation or not. This can be used to study skin areas with normal as well as hyper- or hyposensitive areas.
We now launch a new version with benefical options such as replacability of the nylonfilament, rounded top of the filament to avoid sharpness sensation. A new material for the nylonfilament with less impact for humidity.
