NEW Dynamic Plantar Aesthesiometer (DPA) for mechanical stimulation ^Featured

Additional Info

FEATURE	BENEFIT
The force is automatically applied	Consistency in force application, rate and direction
Maximum force is 100g	Works on a broader range of animal models, molecules, diseases
The user only has to press a button	The test is quicker and less tedious than VF hairs
Double click of the button triggers manual score	Possibility to use manual scoring when animal behaviour is difficult to automatically detect
Force threshold and ramp can be adjusted	More parameters to fit with virtually any experimental need
Touch force and touch pause can be adjusted	The way the probe approaches the paw can be changed, depending on paw sensitivity
Force automated or manual	The force threshold can be scored manually or automatically

Impaired cutaneous sensation is usually first manifested in a loss of light touch detection. So “mechanical” stimulation has a long history of effective clinical use to diagnose pa-thologies of hyper- or hypo-aesthesia, brought about by drugs, neural pathology or experimental lesions, etc.

The Dynamic Plantar Aesthesiometer was developed to apply a reproducible light touch to the rodent plantar surface, and quantify the force which causes the animal to react by withdrawing the paw.
