Used to measure the paw withdrawal reflex when the mouse or rat paw is unexpectedly touched. For evaluating mechanical allodynia and cutaneous sensation levels. Popular non-invasive technique.
Set of 20 monofilaments based on the Semmes Weinstein monofilament set. An ascending series of increasingly stiff filaments (from 0.008 to 300 grams). Features retractable head to protect the filaments, allowing a researcher to carry a few around in a pocket. An optional perforated metal grid platform is available that is comfortable for the animal and easy for viewing the target area.
Especially suggested for sub-gram forces (i.e., severe allodynia) although very time consuming and operator dependent. Whenever possible, the use of the Electronic Von Frey or the Dynamic Plantar Aesthesiometer is suggested for higher throughput and better accuracy.
| Feature | Benefit |
|---|---|
| Starts from very low forceas (0.800 gr) | Detects even the most severe allodynia |
| Retractable filament | Easy to carry and protected from damage |
| Effective use in clinical setting | Used to diagnose pathologies of hyper- or hypo-aesthesia |
| Optional perforated platform available | For convenient stimulation of rodent plantar-surface |
Aesthesio® Tactile Sensory Evaluator Data Chart
When the tip of a fiber of given length and diameter is pressed against the skin at right angle, 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.
