Walk!

separator images

This is one of the programs that I have developed and used for my scientific bio-mechanical publications (ref. 4, 6, 7, 8, 9, 10). This tool performs the 3-D gait analysis of subjects that where recorded with BTS Elite system, even if it can be extended to other 3-D motion acquisition systems. It is possible to filter the 3-D trajectories as well as compute the velocities, accelerations, limbs angles, energies (divided in all the subcomponents), and the covariation plane that was described in details in the publication section (Borghese et. al. 1996). It is also possible to analize EMG data and ground reaction forces acquired in sync with the Elite System. This has been the only Elite Data viewer under Microsoft Windows platform for years, and a lot of computation capabilities are still unsupported by other programs.
