Survey design
Researchers surveyed wheelchair service providers after showing video recordings of the Arc-RAD in use. The device is described as remaining out of the way at rest and self-deploying through an arc when needed. Participants rated 20 potential uses on a five-point scale, from extremely not useful to extremely useful, and supplied written comments.
Ratings across applications
A total of 156 respondents provided information about at least one potential use. Median usefulness ratings were 5.0 for nine uses, mostly those not involving the aided-wheelie position, and 4.0 for ten uses, including many aided-wheelie skills. The remaining use, moving straight sideways, received a median rating of 3.0.
Patterns in responses
For 15 of the 20 uses, at least three-quarters of respondents selected either extremely useful or somewhat useful. Among the other five uses, only moving straight sideways had those favorable responses from fewer than half of participants. Analysis of 668 comments identified positive and negative views, questions or concerns, and other remarks; the authors said these findings will inform further research and development.
