Assessment of neuromuscular function is critical for understanding pathophysiological changes related to motor system dysfunction in numerous animal models of disease. Among numerous methods used for quantification of grip performance in rodents, gauge-based grip strength meters seem to provide the most reliable results, however such instruments are unaffordable by many laboratories. Here we demonstrate how to build a grip strength apparatus for rodents from scratch using a digital kitchen scale, an empty cage and a microcontroller. griPASTA is completely open-source so both hardware and software can be easily modified by the end user to best fit the specific experimental protocols.
