An electrically-powered digital instrument designed to measure: 1) a patient's sensitivity to pain (pain threshold) by applying a painful, calibrated mechanical force (pressure) to the skin; and 2) tactile sensibility (two-point touch discrimination) by application of a thin filament(s) to the skin. It is a hand-held device with a thin filament(s) with a pre-set flexibility intended to apply a known pressure (e.g., two-point aesthesiometer). It is typically used during diagnosis or treatment of nerve injuries and neuropathies.
