The Aesthesio®set of 20 monofilaments is based on the Semmes Weinstein monofilament set, but now features retractable filaments to protect the filament and allow the evaluator to carry a few around in a pocket. Used for evaluating cutaneous sensation levels. One of the most popular non-invasive techniques used.
Individually calibrated to deliver a target force, from 0.008 grams to 300 grams. When the tip of a fiber of given length and diameter is pressed against the skin at right angles, the force of application increases as long as the researcher continues to advance the probe, until the fiber bends. After the fiber bends, continued advance creates more bend, but not more force of application. The Semmes Weinstein set of monofilaments provides an approximately logarithmic scale of actual force, and a linear scale of perceived intensity. They have a long history of effective use in clinical settings, and can be used to diagnose pathologies of hyper- or hypo-aesthesia.
Rodents exhibit a paw withdrawal reflex when the paw is unexpectedly touched. The Touch Test™ Sensory Evaluator can be used on the Plantar surfaces of the foot of a rat or mouse, and the animal will indicate sensation by pulling back its paw.Also Available: Perforated metal platform, laser-cut perforations form a mesh-like open grid of square holes ~5X5 mm. Intervening metal grid is approximately 1mm wide, comfortable to the animal and easy to view the target area of the paw. The platform is coated with a polymer resin that is easy to clean and which will not be spoiled by fluids or waste materials.
