"Wartenberg wheel"의 정의 및 의미

What is a "Wartenberg wheel"?

A Wartenberg wheel, also known as a pinwheel, is a medical tool used for evaluating nerve sensitivity. It has a small, round wheel with sharp spikes coming out from its edge. Healthcare providers gently roll the wheel over the skin to evaluate sensory responses, such as detecting areas of increased sensitivity or numbness. The Wartenberg wheel helps diagnose nerve-related conditions and evaluate nerve function by observing how the nervous system reacts to touch.
