Abstract
Abstract A method for detecting and measuring cutaneous sensory perception. The method utilizes an instrument comprises an elongate tubular housing having a sleeve member extending axially from an end thereof. Mounted on the other end of the tubular housing is a vernier counter adjustment, the operating mechanism of which is disposed internally of the housing. Telescopically positioned within the sleeve is a thin wire-like member or monofilament stimulating element. One end of the monofilament stimulating element extends from the sleeve while the other end is mechanically coupled to the internal operating mechanism of the vernier counter adjustment.
