 Analysis has begun and profiles have been created for the pre-test movements. Graphs depicting the standardized means along with the 2 generalized profiles are shown in Figure 1. For presentation purposes it is necessary to show the standardized values as the variables are on different scales, with hugely varying mean values. Due to the underlying normality assumption, it was necessary to transform the lateral trunk motion variable to the loge scale. In addition, it is necessary to account for the correlation between some of these variables; in particular maximum hip moment and GRFv and HAdT. We are continuing to examine the potential LPA models at this time and will be checking them against the post intervention data to determine any emergent profiles. Comparison of mean KAM, with and without adjustment for age and pubertal status by profile will also be the focus of future analyses.
