What is wartenberg wheel?

The Wartenberg wheel, also known as a pinwheel, is a medical device originally designed by the neurologist Robert Wartenberg as a diagnostic tool to test nerve sensitivity. It is a small, metal wheel with sharp spikes or points arranged radially around the edge.

When the wheel is rolled over the skin, the spikes stimulate the nerve endings, causing a prickling sensation that can range from mild to intense depending on the pressure applied. This can be used to assess nerve function and sensitivity, as well as provide therapeutic sensory stimulation.

In addition to its medical use, the Wartenberg wheel is also popular in BDSM and sensation play, where it is used to enhance and intensify sensory experiences during activities such as bondage, domination and submission, and other forms of erotic play. It can be used to gently stimulate the skin, create a tickling or scratching sensation, or inflict a mild amount of pain depending on the user's preference.

Overall, the Wartenberg wheel is a versatile and effective tool for both medical and recreational purposes, providing a unique sensory experience that can be tailored to individual preferences.
