|MDS_24042_sm_SuppInfo.pdf||165K||Appendix Caption This graph clearly demonstrates the interaction of feedback by group within each height that participants gave perceptual judgments for. It is evident that individuals with Parkinson's disease show greater toe elevations when compared to healthy control participants when relying only on proprioception across all heights. However, once individuals with PD have vision available, you can see that their judgements become very similar to the healthy control participants across all heights estimated. In addition, this graph also illustrates the feedback by height interaction. In both groups, estimation of heights made with vision available, are more accurate than estimations given with only proprioception available. Within each feedback condition, each height is significantly different from each other, demonstrating that all participants were scaling their judgments to the height of the obstacle.|
