While normal rats and mice distribute weight equally on both paws, the ratio of weight distribution between injured and non injured paw is a natural measure of the level of discomfort in the injured paw, that correlates with the Paw Pressure Analgesia Meter (Randall and Sellito test). Bioseb Incapacitance Test or Static Weight Bearing (SWB) Test allows you to measure this weight distribution and thus to easily and accuratly estimate the level of discomfort.

Bioseb Incapacitance Test (Static Weight Bearing) shows some unique features as:

• A non pain-inducing method to measure discomfort: the animal stands and makes a natural adjustment to the degree of pain by adapting weight distribution on both rear paws.

• An objective measurement solution: dual channel scale based measurement is done independently of the operator’s reaction time or subjective judgement about animal’s flinching.

• An easy and precise instrument: no restraint requirements, a footswitch to tare scales, direct display of the average value on the LCD for each of the back paws.

• A stand alone instrument: no PC is required for running the incapacitance test, although you have the possibility to send collected data from the instrument to a PC through the integrated RS232 interface. Can also be run on battery.

• The Incapacitance (Static Weight Bearing) Test allows to compute and dispay statistics (mean, sd) for the groups of animals under test during the measurements,

• Units are selected by the user in grams, Newtons or oz/lbs.

• The Instrument as an internal memory of up to 200 individual values (ie 1 animal, 2 paws) or up to 200 groups when the statistics are used. Those values are available for edition directly on the display, or to be printed out or transferred to a PC, later on. Transfert includes date and time for glp protocols.

• Independent platform and control unit: a 1 meter cable allows to keep some distance between the animal and the operator, reducing the placement time.
