A manual, non-powered instrument designed to measure: 1) a patient's sensitivity to pain (pain threshold) by applying a painful, calibrated mechanical force to the skin; and 2) tactile sensibility by application of a thin filament(s) to the skin. It is typically a holder/pen which includes a strain gauge, a pressure algesimeter tip(s), and a thin filament(s) with a pre-set flexibility intended to apply a known pressure (point aesthesiometer). The device is typically used to evaluate the effects of pain after the use of anaesthesia/analgesics and/or during diagnosis or treatment of nerve injuries and neuropathies. This is a reusable device when the consumable products have been replenished.
