The NEW original Plantar Test for thermal stimulation (Hargreaves Apparatus) Featured

In 1988 K. Hargreaves et al. showed paw withdrawal latency in rodents by thermally stimulating the paws through a transparent glass pane.

This method radically enhanced pain behavioral testing possibilities and was made available to the scientific community worldwide by Ugo Basile, which started producing the Plantar Test device for mice and rats.

The amount and duration of thermal energy can be set to the desired level, the thermal emitter is pointed to the freely moving mouse or rat and the time it takes to the paw to withdrawal is automatically recorded.

 

 

The Plantar test is performed through a very simple procedure, during which a rodent hindpaw is stimulated with a radiant heat, through a glass pane, using the plantar paw as surface to be irradiated.

The time latency to paw withdrawal, given a certain energy delivered (adjustable in the instrument), is effectively the test end-point.

This NEW VERSION of the classic Ugo Basile Plantar Test proudly introduces a number of NEW FEATURES for even simpler and better experiments:

- Automatic measurement of the paw wihdrawal latency time and energy AND also manual scoring option (for those cases where the animal motory response is unusual or difficult to score)

- Touch screen for complete management of settings, testing, result view and download

 The Plantar Test comes as a full package containing all that is needed to run an experiments with both rats and mice. It consists of and includes as standard:

- A movable I.R. (infrared) generator with embedded paw withdrawal detector

- A glass pane underneath which the IR source is placed

- Modular animal enclosures positioned above the glass pane and that can hold up to 6 rats or 12 mice 

- A touch-screen electronic unit which controls all settings and collects data

 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 drive.

    Determination of acute nociceptive thermal threshold in laboratory animals has primarily relied upon the tail flick and hot plate methods.

    Although both methods are 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 and unhandled during experiments.

    In addition, unilateral/controlateral experimental designs are possible by the single stimulation and different teatments of each individual paw.
