Wartenberg wheelとは 意味・読み方・使い方

A Wartenberg wheel, also called a Wartenberg pinwheel or Wartenberg neurowheel, is a medical device for neurological use. It was originally designed by Dr Robert Wartenberg to test nerve reactions (sensitivity) as it rolled systematically 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. Because of hygienic concerns, these devices are hardly used any more.
