Movement analyses using stereophotogrammetry are commonly conducted in order to assess pathologic or healthy movements under different conditions. The plug-in gait marker set, used so far at the movement laboratory at ZHAW, is depending on precise placement of markers on specific anatomical landmarks. However, when, for example, assistive medical devices such as exoskeletons are tested, these landmarks may be obscured and the markers cannot be placed appropriately and the validity of the measurement is decreased.
Therefore, a new cluster marker approach for the lower body was developed to overcome these limitations. Furthermore, during a past project, a new trunk marker model was developed and validated (Rast et al. 2016).
For both marker sets (lower body and trunk), normative data is necessary in order to classify movement data obtained through studies.
