Product Detail

Plantar Test

The new Plantar Test Instrument (Hargreave’s Method) measures response to infrared heat stimulus, applied to the plantar surface. Our Plantar Test is the original apparatus, designed in close cooperation with Prof. Ken Hargreaves, who devised the method.

Focus the infrared source below the Plantar surface and with the press of a button … latency to paw withdrawal and infrared intensity are recorded automatically (i.e. no manual scoring, as in other models available on the market!).
 
Classically the measurement of acute nociceptive thermal threshold in laboratory animals has primarily relied upon the tail flick and hot plate methods. Although both methods are still used frequently in pharmacological studies, they are not without limitation. In addition, neither method has been extended to investigating behavioural responses to hyperalgesia.
 
The Plantar Test represents a remarkable advance in methodology, as it combines the best features of all other methods of measuring pain sensitivity. Unique to the Plantar Test, the animal is unrestrained during experiments. Unlike other models available on the market, time latency is recorded automatically by a fiber optic sensor, without having to rely on the experimenter observation of the animal behaviour, thus avoiding unwanted experimental bias.
 
Proprietary to our model is a specific filter, cutting off the visible part of the light spectrum, which would disturb the animal on test and provide an unwanted clue. A feedback circuit detects false starts.
 

 

 
Data appear on the front panel and may be exported to a USB pen-drive, or to the PC via USB; both USB pen-drive and software are included in the standard package.
