At each paw withdrawal, the Dynamic Plantar Aesthesiometer (DPA) automatically detects and records latency time, and actual force at the time of paw withdrawal reflex. A movable force actuator is positioned below the plantar surface of the animal and the desired force and force speed (ramp) is applied, as preset by the operator. A Von Frey–type 0.5mm filament exerts increasing force, until the animal twitches its paw.
The DPA encompasses:
- a movable touch-stimulator unit, well proven in previous model, complete with filament actuator and adjustable angled-mirror
- a microprocessor controlled electronic unit, of new design provided with graphic display, internal memory for data storage, USB key and optional printer
- a large testing surface (perforated metal platform)
- a new modular animal enclosure, offering from 3 to 12 spaces, convenient to hold rats and mice
Data may be easily ported to the memory stick or directly to computer.
This unit is used for mice/rats only
