- A novel approach to solve the "missing marker problem" in marker-based motion analysis that exploits the segment coordination patterns in multi-limb motion dataPeter Andreas Federolf
Department of Physical Performance, Norwegian School of Sport Sciences, Oslo, Norway
PLoS ONE 8:e78689. 2013..Estimating missing information cannot be avoided entirely in many situations in human motion analysis. For some of these situations, the proposed reconstruction method may provide a better solution than what is currently available. ..

- Discrimination of gender-, speed-, and shoe-dependent movement patterns in runners using full-body kinematicsChristian Maurer
Human Performance Laboratory, Faculty of Kinesiology, University of Calgary, Calgary, Alberta, Canada
Gait Posture 36:40-5. 2012..Within the well-defined vector space spanned by the data of all subjects, higher principal components should also be considered because these components show the differences that result from small interventions such as footwear changes...
