About this item
The Semmes-Weinstein monofilaments provide an approximate logarithmic scale of actual force, and a linear scale of perceived intensity. Ideal for use in clinical settings, and can be used to diagnose pathologies of hyper or hypo-aesthesia.
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
Rodents exhibit a paw withdrawal reflex when the paw is unexpectedly touched. Touch Test™ sensory evaluator can be used on the Plantar surfaces of the foot of a rat or mouse.
Subsets within the set of 20 probes distinguish pathologies on different parts of the body (foot, hand, lip, cheek).
After the fiber bends, continued advance creates more bend, but not more force of application. This makes it possible for the researcher using a hand-held probe to apply a reproducible force, within a wide tolerance, to the skin surface.
