產品名稱:動態腳步壓力測試系統 Dynamic weight bearing : New incapacitance test
產品編號:DWB–M
廠  牌:BioSeb

    Presentation
    Weight Bearing of rodents, also named ? incapacitance ? test, is well known in nociception research studies. Traditional ? static ? type instruments have been used in the last years.

    Those instruments, although showing well correlated results vs paw pressure vocalization test, calibrated Von Frey filaments ... (cf Richebe P, Laulin JP, Simonnet G, Anesthesiology 2005, Pain 2007,.... ), are highly dependant on the animal positionning inside a stressfull restrainer. This makes them time consuming and difficult to use particularly when large number of rodents are considered

    Operation principle
    Bioseb has now developped a new test with a floor instrumented cage , allowing to measure independantly the weight bore by each limb of a free moving animal. The system accuracy and resolution are insured via a metrological calibration performed prior to the data capture. During the data capture, the raw datas for each paw are synchronized with the images from a video camera and the averaged values are encrypted and recorded on a pc (via an usb link) with a sampling rate of 10 Hz .

    Analysis and replay can be performed on site or remotely. During the analysis and replay, the operator can check and secure each limb recognition.
    The weight distribution of the animal, per limb, is then shown in the result window, for each time period with the mean and the variation coefficient.
