aesthesiometer

Instrument for the measurement of sensitivity, especially tactile. The cornea and eyelid margins are the ocular structures measured. There are many types of aesthesiometers. The most common is that of Cochet-Bonnet (Fig. A7). It consists of a nylon monofilament of constant diameter which, depending upon its length, can exert more or less pressure. The length at which the subject responds to represents the corneal touch threshold. Others are non-contact and use a pulse of pressurised air or gas to stimulate the cornea. Note: also spelt esthesiometer. See corneal fragility; corneal hyperaesthesia; corneal sensitivity; corneal touch threshold.

Three measures of peripheral sensation were made: tactile sensitivity at the ankle (assessed using a Semmes - Weinstein Pressure Aesthesiometer) [14], vibration sense at the knee (assessed using an electronic device which drove a 20O Hz vibration of varying intensity), and proprioception, which was tested using an apparatus which measured any error in matching the position of the lower limbs (measured in degrees) [12].
