Ugo Basile introduces an Electronic Von Frey of original desing, the e-VF, for applying light touch to the rodent foot and automatic assessment of Hypersensitivity and Allodynia in rats and mice. The 38450 automatically records the animal response to user-controlled application of force rate.
A touch stimulator transducer is mounted on a Perspex handle, so that routine procedures may be employed to examine and test the animal skin sensitivity. The prism of original design is of great help to localize the aimed stimulation area
The completion of each test may be indicated either by the sudden release of the paw or by pressing the external foot-pedal. The display then gives the operator a summary of the results of the test (i.e. force and time corresponding to the animal response).
The rate of application of the force is set by the operator and the e-VF includes software tools that help the operator in consistently applying the force at the desired rate. The results of several hundred tests may be stored in the e-VF for transfer them to a PC when convenient
The instrument includes:
an electronic unit
the touch stimulator with the prism of original design
and can be completed with the 37450-278 Base assembly for plantar stimulation
