I have been working with Greg Borenstien for a while now on creating an open source tool for visualizing human movement data. You can see all his code here on github. We needed some data that had x, y, and z positions of human joints over time during a certain task, as well as angular velocities and joint torques. The only freely available source we found that had all of this kinematic and kinetic data was the appendix of Biomechanics and Motor Control of Human Movement by the late David Winter. There was a helpful thread on the Biomch-L forum that led to some digital versions of this appendix. However, there was never a comprehensive Excel file posted with all the data.
So, here it is: Winter_Appendix_data.
It’s just the right leg and a torso point, but Greg got a visualization up and running quickly:
