ABSTRACT:
An apparatus for measuring skin tactile thresholds and, thus, skin irritation comprises a set of unitarily formed monofilaments whose tips are textured and curved. The unitary tip of the monofilament accordingly does not break or fall off, and due to its texture and curvature is accordingly capable of contacting a skin surface with substantially no slippage for eliciting tactile pressure stimulations that are more consistently of the pressure type than the conventional esthesiometer, which elicits both pressure and pain stimulations randomly. The present apparatus consistently stimulates a skin site with pressure stimuli of various intensities and the perceptual experience of each pressure stimulation can accordingly be accurately recorded in each of two modalities: touch and pain. A method of making the unitarily formed stimulating monofilament comprises providing an elongated monofilament having a tip end portion; applying heat to the tip end portion until the tip end portion balls-up and becomes curved and textured; and mounting a non-free end portion of the monofilament to a handle member.
