The Dynamic Plantar Aesthesiometer was designed to automate the assessment of “touch sensitivity” on the plantar surface of rats or mice and comes ready with all necessary accessories to work with both Mice and Rats. It is known by some as the Electronic Von Frey or Plantar Von Frey instrument.
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 rigid filament exerts increasing force, until the animal twitches its paw.
Data may be easily ported to the memory stick or directly to computer.
The Ugo Basile Dynamic Plantar Aesthesiometer 37550 is the quickest and most accurate way of delivering a mechanical stimulation and measuring a response, all automatically!
NEW IN THE 37550 DEVICE:
- Maximum Force is 100g (formerly 50g)
- Touching force and touching pause is adjustable (to control the stimulus approaching phase)
- Paw withdrawal detection is automatic, but can also be manually detected, depending on the experimenter preference
- TTL I/O for trigger input and output
- Embedded hard disk so that the USB key is used for data export/import only

| 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.
