Validating optical motion capture assessments of the dynamic aspects of work

Abstract

The objective of this study is to validate two three-dimensional motion systems used capture human movement; the Lumbar Motion Monitor (LMM) and optical motion capture. Marras et al. captured the accuracy and reliability of optical motion capture and the LMM in a 1992 validation study, and found several benefits of using the LMM for ergonomic evaluations. However, since 1992, several advances have been made in the field of digital human modeling and optical motion capture, and it is believed that a modern validation of the two systems could serve others in academic and industry alike when choosing a methodology toward capturing ergonomie data. The purpose of this research is to validate the methods of collecting dynamic data and predicting injury risk in humans during lifting procedures. © Springer-Verlag Berlin Heidelberg 2007.
