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:
“Let go thy hold when a great wheel runs down a hill lest it break thy neck with following; but the great one that goes upward, let him draw thee after.”
—William Shakespeare (1564–1616)
