Touch sensitivity is traditionally tested with Von Frey filaments, which is a tedious and experimenter-dependent assay.
The Dynamic Plantar Aesthesiometer is a unique system, which fully automates the amount of force applied by an electromagnetic, silent motor exerting from 0 to 100 grams at a rate adjustable from 0 to 50 seconds.
When the animal responds, by withdrawing its paw, the device automatically scores the time and the force at which the response occurred and the data can be stored or exported in CSV format.
One model for Mice or Rats in modular enclosures (up to 6 rats or 12 mice)
The Ugo Basile system comes complete with:
Additional features include:
Feature | Benefit |
---|---|
Fully automated force and force rate application |
Higher throughput and improved accuracy |
Automated scoring of paw withdrawal |
Higher throughput and improved accuracy, thanks to decrease in experimenter bias |
Large force range (0-100 grams) |
Flexibility for performing many types of experiments from severe allodynia to hyperalgesia |
Touch force and touch pause can be adjusted |
The way the probe approaches the paw can be changed, depending on paw sensitivity |
Touch screen and multiple data output (internal storage and CSV export) |
Data can be quickly saved in the electronic unit or on the USB stick for CSV export and further analysis |
Optional manual scoring of paw withdrawal |
Allows for scoring animals which present an unusual position of the paw, and do require the experimenter to visually score |
Painted metal grid and modular animal cages |
Works with rats and mice in high throughput (6 rats and 12 mice at the time) |

The Dynamic Plantar Aesthesiometer has been used in a variety of applications in nerve injury, from partial sciatic nerve ligation (PNL, to chronic constrinction injury (CCI) and spinal nerve ligation (SNL) to screen phenotypes and drugs to treat allodynia and hyperalgesia.
The main advantages of the Dynamic Plantar Aesthesiometer over the Von Frey Hairs, Semmes-Weinstein set of monofilaments and the Electronic Von Frey systems (hand-held) are:
Altogether this brings about a high reproducibility, sensitivity and accuracy which no other mechanical stimulation application can provide. The sensitivity is by far the result of the fact that the force application does not rely on hand movement.
Moreover, the Dynamic Plantar Aesthesiometer, differently than Von Frey filaments, provide a linear and not logarithmic scale of stimulation.
