Wartenberg wheel
Medical device for neurological use

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 was rolled systematically across the skin. 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.
Begin with the source’s own compact description: “Wartenberg wheel” is medical device for neurological use. The dossier treats that line as a proposition to test through Wartenberg, wheel and Medical, not as a finished interpretation.
Why this record matters
The phrase “medical device for neurological use” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 21, 2026.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
