NEW Dynamic Weight Bearing Test<br />
Measuring the Postural Equilibrium on Freely Moving Rodents<br />
Dynamic Weight<br />
Bearing Test<br />
Analysis and replay can be performed on-site or remotely. Replaying the<br />
experiment with the recorded video file allows the operator to further<br />
complement the posture and behavior of the animal, enhancing the<br />
interest of the test. During this time, the user can check and secure each<br />
limb recognition. The weight distribution of the animal, per limb, is shown<br />
in the result window for each time period with the mean and variation<br />
coefficient. All data is presented in the Excel file.<br />
Key Features<br />
➤ Measure independently the weight bore by each limb of a<br />
freely moving animal<br />
➤ Data capture allows for analysis and replay to be performed<br />
for user validation of data<br />
➤ Accuracy and resolution insured by an initial calibration<br />
➤ High throughput possible in this minimal stress to the animal<br />
hardware<br />
Parameters Measured<br />
➤ Weight bore on each limb, averaged and coefficient of<br />
variation<br />
➤ Time period, mean and coefficient of variation<br />
➤ Raw data is encrypted (GLP) and recorded with a sampling<br />
rate of 10 Hz including synchronized video recording<br />
Components Included<br />
➤ Animal cage<br />
➤ One sensor<br />
➤ USB interface<br />
➤ Webcam<br />
➤ Software<br />
Dynamic Weight Bearing Test<br />
Newly developed, our Dynamic Weight Bearing Test, features a floor<br />
instrumented cage. This allows independent measurement of the weight<br />
bore by each limb for the freely moving animal.<br />
This system accuracy and resolution are ensured via a metrological<br />
calibration performed prior to the data capture. During the data capture,<br />
the raw data for each paw are synchronized with the images from a video<br />
camera and the averaged values are encrypted and recorded on a PC<br />
through a USB link along with the sampling rate of 10 Hz.<br />
