Description
Aesthesiometer Three-point is a handheld nerve sensory evaluator designed for quantitative tactile testing. It supports two-point discrimination assessments by delivering concurrent stimuli from two contact points, while a third point enables rapid switching to one-point testing, simplifying exam sequences in clinical settings.
Specifications: A linear sliding scale calibrated to the nearest 0.1 cm, spanning approximately 0–13 cm with clear, high-contrast graduations for quick readings. The device employs vinyl tips to minimize temperature-related variation in sensation and to provide consistent contact pressure across repeated trials. The three-prong arrangement remains fixed to ensure reproducible spacing between stimuli across tests.
Construction and use: a rigid housing couples with a smooth sliding scale for reliable repeat measurements. Ideal for neurology and rehabilitation exams, it supports mapping of sensory thresholds on fingers, hands, and forearms. Operators can document exact threshold values, compare against reference norms, and track changes over time in patient progress without device recalibration.
