A Wartenberg wheel, also called a Wartenberg pinwheel or Wartenberg neurowheel, is a medical device for neurological use. The wheel was designed to test nerve reactions (sensitivity) as it rolled systematically across the skin.[1] A Wartenberg wheel is generally made of stainless steel with a handle of approximately 18 centimetres (7 in) 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 rarely used for medical purposes.[2]
Robert Wartenberg, namesake of the Wartenberg wheel, is sometimes incorrectly credited as its inventor.[3] According to Wartenberg himself, the device was in widespread use in Europe when he lived in Germany.[3] While he did not invent it, he found it "an indispensable part of the outfit for everyday neurologic practice," and recommended its use to his colleagues in the US.[3]
The Wartenberg wheel is also used as a sensation sex toy, and is often used to tickle a person (also called a ‘lee, short for “ticklee”) in the act of tickle fetishism. It is sometimes used in other settings while connected to a violet wand electrical device.[4]
Clothing pattern-making can use a version of the Wartenberg wheel, called a pounce wheel, to transfer markings from paper to fabric. Pounce wheels resemble standard Wartenberg wheels in shape but have wooden or plastic handles.
