| A Wartenberg wheel (also called a pinwheel or neurowheel) is a medical device for neurological use. It was originally designed by Dr Robert Wartenberg to test nerve reactions as it glided 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 around as it is rolled across the flesh. A disposable plastic version is available. Wartenberg wheels are a popular BDSM toy. |
