VISUAL ANALYSIS AND QUANTITATIVE
ASSESSMENT OF HUMAN MOVEMENT
by
VENUSTIANO SOANCATL AGUILAR
1. Techniques for visualizing raw data such as heat maps and violin plots
provide quick insight into the structure of the data for further direc-tions of data exploration.
- Chapters 2 and 3
2. By adding objective metrics to the visualization of overlapping violin
plots their interpretation can be strengthened.
- Chapters 2 and 3
3. Local features of movement trajectories can be used to distinguish
older from younger participants and can also be used to distinguish patients with a coordination disorder from healthy controls
- Chapters 2, 3 and 5
4. In addition to speed, local curvature derived from the movement
tra-jectories of body parts provides valuable information to assess balance performance in real-time.
- Chapter 3
5. Besides aiding in distinguishing between two groups of people with
different movement characteristics, probabilistic scales can provide meaningful insight in movement performance.
- Chapters 3 and 5
6. There is no strict division between young and old, nor between healthy
and pathological balance
-Chapters 2, and 3
7. Probabilistic values can be used to monitor changes in balance
perfor-mance over short periods of time in the order of minutes, as well as over longer periods of time in the order of weeks or months
-Chapter 4.
8. Maintaining and achieving balance and stability should be seriously
considered in all aspects of human life.
9. Assessing lack of coordination is a piece of cake compared to finding
