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.
Aesthesio® 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.
|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|
