Dynamic Plantar Aesthesiometer
The Dynamic Plantar Aesthesiometer is the only device that automatically delivers the desired force at the desired rate and records paw withdrawal without experimenter bias. An electromagnetic motor delivers 0–100 g of force at adjustable rates, replacing manual Von Frey testing.
The Dynamic Plantar Aesthesiometer is the only device 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. This fully automated system replaces tedious manual Von Frey testing using an electromagnetic motor delivering 0–100 grams of force at adjustable rates.
Research Applications
The Dynamic Plantar Aesthesiometer is used to evaluate mechanical allodynia and hyperalgesia in rodent pain models, including neuropathic, inflammatory, and post-surgical pain. Its automated force delivery eliminates experimenter bias, making it ideal for blinded preclinical drug studies and phenotyping of genetically modified pain models where objective measurement is critical.

The Dynamic Plantar Aesthesiometer (Cat. 37550) automates Von Frey-style mechanical allodynia testing, delivering controlled increasing force and recording paw withdrawal threshold. It is widely cited in neuropathic pain models (PNL, CCI, SNL) and inflammatory pain research for drug screening.
How does the Dynamic Plantar Aesthesiometer eliminate experimenter bias?
The electromagnetic motor delivers a precisely controlled and reproducible force ramp automatically, removing the experimenter from the measurement loop entirely.
What force range and rate can be programmed?
Force ranges from 0.5 to 100 g (in 0.1 g steps), and the force increasing rate is set from 0 to 50 seconds (in 1 s steps).
How many animals can be tested simultaneously?
Up to 12 mice or 6 rats can be housed in the modular enclosures simultaneously during testing.
What measurement modes are available?
Both Automatic (paw withdrawal detected automatically) and Manual (experimenter scores responses) modes are available.
What is the warranty?
12 months standard warranty, extendable to 24 months upon product registration.
