Propositions belonging to the thesis
Development of a wheelchair propulsion
laboratory
Rick de Klerk
1. The heterogeneity of lab-based equipment and the lack of consensus in the field limit the generalizability of results and the applicability of the existing knowledge base. – this thesis
2. The measurement of power output is critical to the study of handrim wheelchair propulsion. – this thesis
3. The implementation of the Esseda – an instrumented servo-driven wheelchair roller ergometer – in wheelchair propulsion laboratories will benefit future research, rehabilitation, and sports practice. – this thesis
4. A low-cost and portable calibration system is essential for stable and valid calibration testing within and between ergometers. – this thesis
5. The Esseda is a valid alternative to overground and treadmill testing. – this thesis
6. Wheelchair racing practice on an ergometer improves efficiency and technique in novices, but consistent training, guidance, and feedback are needed to reach those of an experienced athlete. – this thesis
7. Optimization of power-assisted wheelchairs requires algorithms that account for individual propulsion characteristics, estimates of shoulder loading, and environmental conditions. – this thesis
8. Merely quantitative differences beyond a certain point pass into qualitative changes. – Karl Marx
9. If the implementation is hard to explain, it’s a bad idea. If the implementation is easy to explain, it may be a good idea. – Tim Peters
