What is wartenberg pinwheel?

The Wartenberg pinwheel, also known as the Wartenberg neurological pinwheel, is a medical instrument used to test sensory perception and nerve function in patients. It was first developed by German neurologist Dr. Robert Wartenberg in the 1940s.

The pinwheel consists of a small wheel with sharp spikes that can be rolled across a patient's skin to assess their ability to detect sensations such as pressure, touch, and pain. The spikes are designed to be sharp enough to stimulate the nerves, but not sharp enough to break the skin or cause injury.

In addition to its medical uses, the Wartenberg pinwheel has also become popular in BDSM and fetish communities as a tool for sensory play and erotic stimulation. It can be used to create sensations ranging from gentle tickling to intense prickling, depending on the pressure and speed at which it is used.

Overall, the Wartenberg pinwheel is a versatile tool that can be used for both medical and recreational purposes, making it a unique and interesting instrument in the field of sensory testing and sensory play.
