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:
“The word “revolution” itself has become not only a dead relic of Leftism, but a key to the deadendedness of male politics: the “revolution” of a wheel which returns in the end to the same place; the “revolving door” of a politics which has “liberated” women only to use them, and only within the limits of male tolerance.”
—Adrienne Rich (b. 1929)
