Wartenberg Neurological Pin-wheel 19cm

Clinical Application

Designed for reliable bedside and clinic neurological assessment, this instrument provides repeatable cutaneous stimulation to evaluate pain and touch pathways. It is commonly used during peripheral nerve exams, dermatome mapping, post-operative sensory checks, neurology consultations, and intraoperative or post-procedural sensory comparisons. The pin-wheel delivers a controlled, focal pinprick stimulus that helps distinguish nociceptive (pinprick) from light-touch sensations.

Design & Configuration

The rotating wheel of sharp pins produces a consistent, rapidly repeating stimulus as it is drawn across the skin; this rotation minimizes variability between strokes compared with single-pin testing. The straight handle provides ergonomic control and a 19 cm overall length that gives clinicians comfortable reach and fine control for mapping small or difficult-to-access areas. The compact wheel diameter and closely spaced pins enable precise localization of sensory thresholds and dermatomal boundaries.
