The Dynamic Plantar Aesthesiometer is the only device available on the market that automatically delivers the desired force at the desired rate and automatically records paw withdrawal, providing both the amount of force and the time taken in a completely unbiased manner.

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.
