The Baseline Fold-Up Monofilament evaluator is used to measure cutaneous sensory perception threshold. The monofilament test provides a non-invasive evaluation with objective and repeatable results. Each monofilament represents a unique amount of force which is marked by force and size. These monofilaments feature an easy to fold nylon filament for protection as well as easy storage and portability. The 2-piece set includes both 2.83 and 3.61(Normal Limit Set) cutaneous sensation levels and 4.56 and 5.07(Protective Sensation) cutaneous sensation levels.
