Incapacitance Tester

An easy and painless solution for assessing the level of discomfort (incapacitation) in the inflamed paw of a small animal such as a rat or mouse by measuring postural balance “independent of the operator.” The static weight-bearing instrument is ideal for your research on analgesia and nociception in rodents: osteoarthritis, cartilage degeneration, inflammation patterns, nerve injury patterns, and more. New model with a brand new touch-screen console. While normal rats and mice distribute weight equally on both paws, the ratio of weight distribution between the injured and uninjured paw is a natural measure of the level of discomfort in a rodent’s injured paw, which correlates with the Paw Pressure Analgesia Meter. By continuously measuring the weight borne by each paw, the Static Weight Bearing Incapacitance Test allows objective measurement of spontaneous pain by assessing postural balance, thus opening up research fields not available when using traditional methods (such as the Randall and Selitto test), which can only measure nociceptive thresholds and pain sensitivity using experimental nociceptive stimuli. Research applications include nerve or tissue injury, neuropathy, carrageenan, incision recovery, osteoarthritis, cartilage degeneration, models of inflammation (CFA), models of peripheral nerve injury, models of mechanical hyperalgia, models of bone cancer pain, and more…
