3.3.4 Clear Floor Length
The difference between the maximum length in the UDI and Seeger studies and the others is so great that they are probably due to the presence of unusually large people and/or devices, or...

3.3.5 Seat Height
This is probably due to the increasing use of positioning systems, thick cushions and the availability of a wider range of wheel sizes since the 1970’s....

Implication for Standards and Design
Close to 200 community dwelling adults who independently transfer have been evaluated during phases 1 and 2 combined of this multi-year study. The main difference between phase 1...

Conclusion
During this second phase of the independent wheelchair transfer study, platform transfers with and without grab-bars and a backrest and two-step transfers were evaluated. The study...
