A Novel Technique for Creating Useful Estimates of Human Body Mechanics from Simple Digital Video

This document contains the results of an experiment conducted in the Biomechanics Research Laboratory at the University of Miami. Vicon motion capture data are used as a baseline for comparing values generated by an innovative motion capture technique using digital video analysis and other software packages. Marker locations, knee angle, ankle angle, knee moment and ankle moment values were produced by each system. The values show statistically significant differences, however if used as an estimator, digital analysis can be of great value. Possible applications for the use of the innovative video analysis technique are discussed. Methods for improving the accuracy and precision of the digital video motion analysis technique are outlined
