VASIC

Sep 19, 2018

In HardwareX, Brendan Drackley and colleagues share VASIC, an open source weight-bearing device for high-throughput and unbiased behavioral pain assessment in rodents.


The assessment of pain in animal models is a key component in understanding and developing treatments for chronic pain. Drackley and colleagues developed VASIC (Voluntary Access Static Incapacitance Chamber), a modified version of a weight-bearing test. A brief water deprivation encourages rats or mice to seek water in a test chamber, set up with a weighing platforms under the water spout, which can assess weight shifting to an unaffected side in animals with damage to nerves or inflammatory pain. The design incorporates a custom printed circuit board (available from the paper), infrared sensor, Arduino microcontroller, 3D printed parts, and open source software for analysis. A full parts list, links to files, and data from a validation study are available in their paper.
