Abstract: Objective To establish a three- dimensional hindlimb gait data toolkit (THGT) for healthy and spinal cord injured (SCI) non-human primate (rhesus monkey) based on Matlab to realize upload of original data, automatic gait division, calculation and drawing of multiple gait parameters, etc. Methods Vicon system was used to collect three-dimensional hindlimb gait data of healthy and SCI (after 6 weeks) rhesus monkey to obtain the kinematics data of both hindlimbs in continuous strides. It was analyzed with THGT to process the gait division, calculation and drawing of multiple gait parameters. Results THGT read the data, distinguished cycles of gait, calculated 140 kinds of gait parameters and drew graphs of the results. Conclusion THGT extends the universality of the Vicon data, realizes automatically gait division and friendly interactive interface, and puts out the visible results.
