A Wartenberg wheel, also called a Wartenberg pinwheel or Wartenberg neurowheel, is a medical device for neurological use. It was originally designed by Robert Wartenberg to test nerve reactions (sensitivity) as it rolled systematically across the skin. A Wartenberg wheel is generally made of stainless steel with a handle of approximately seven inches in length. The wheel, which has evenly-spaced radiating sharp pins, rotates as it is rolled across the flesh. A disposable plastic version is available. Because of hygienic concerns, these devices are hardly used any more.
The Wartenberg wheel is also used as a BDSM or sensation sex toy.
Famous quotes containing the word wheel:
“So I was glad of the fog’s
Taking me to you
Undetermined summer thing eaten
Of grief and passage where you stay.
The wheel is ready to turn again.”
—John Ashbery (b. 1927)
