Pinwheel aesthesiometer

A pinwheel aesthesiometer is a handheld instrument used to assess a patient's sense of touch by presenting rods of varying diameters against the skin. The device features a rotating disc with protruding rods that differ in size, which are manually rolled over the skin to evaluate tactile discrimination, and may include sharply pointed rods to test pain sensation as part of neurological screening.

This category of device is intended for reuse after appropriate cleaning and is typically employed in clinical settings such as physical examinations, diabetes-related foot assessments, or leprosy screening programs to detect peripheral neuropathy. As a manual, non-invasive tool, it does not incorporate electronic components or software and is supplied as a reusable diagnostic aid for sensory evaluation.
