Analgesia NEW Plantar Test (Hargreaves Apparatus) The Plantar Test Instrument (Hargreave’s Method) measures response to infrared heat stimulus, applied to the plantar surface. This 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!). 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 behavior, thus avoiding unwanted experimental bias. A specific filter is used to cut 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.
