Point aesthesiometer

A point aesthesiometer is a handheld device used to assess tactile sensitivity by applying precise pressure to the skin with a thin filament. Clinicians rely on it to diagnose nerve damage or conditions like diabetic neuropathy, leprosy, or peripheral neuropathy by measuring a patient’s ability to detect light touch. The device’s adjustable or pre-set filament flexibility helps determine thresholds of sensation, aiding in treatment planning or monitoring progression. It is commonly used in neurological exams to evaluate sensory function in specific areas of the body.

These devices are typically reusable and designed for clinical use, often requiring calibration or maintenance to ensure accuracy. Regulation varies by jurisdiction, but they are generally classified as medical devices due to their diagnostic purpose. Availability may depend on local healthcare standards, with some models requiring professional training for proper use. Always check local guidelines before selecting or using one in a clinical setting.
