- Concept proposal for a detachable exoskeleton-wheelchair to improve mobility and health
- Proceedings of 2013 IEEE International Conference on Rehabilitation Robotics, June 24-26, 2013 Seattle, Washington USA. Wheelchair use has consequences to quality of life in at least two areas: 1) health issues such as pressure sores and chronic overuse injury; and 2) access problems due to the inaccessible nature of the built and natural environments that are most amenable to upright postures. Even with these concerns, wheelchairs are still the best form of mobility for many people (e.g. they are relatively easy to transfer into and propel). However, wheelchairs are simply not transformative, i.e. they do not allow a person with a disability to attain a level of mobility performance that approaches that of their non-disabled peers, nor do they typically allow for face to face interactions and full participation in the community. Wheelchairs also do not typically support ongoing therapeutic benefits for the user. To address the inadequacy of existing wheelchairs, we are merging two evolving technologies into a coherent new mobility device. The first is dynamic wheeled mobility, which adds significant functionality to conventional wheelchairs through the use of on-the-fly adjustable positioning. The second is powered walking exoskeletons, which enable highly desired standing and walking functions, as well as therapeutic benefits associated with rehabilitation gait training. Unfortunately, exoskeletons have significant usability concerns such as slow speed, limited range, potential to cause skin issues, and difficult transfers. A new concept of docking a detachable exoskeleton to a wheeled frame has been developed to address these issues. The design goal is a single mobility device that not only optimizes daily activities (i.e. wheelchair seating and propulsion with dynamic positioning), but also serves as an easy-to-use rehabilitation tool for therapeutic benefits (i.e. a detachable powered exoskeleton for walking sojourns). This has significant potential benefits for the lives of people with mobility impairments., Conference paper, Published.

- A scoping review of data logger technologies used with manual wheelchairs
- Proceedings of 2015 RESNA Annual Conference. In recent years, more and more studies are using data logger technologies to document driving and physiological characteristics of manual wheelchair users. However, the technologies used offer marked differences in characteristics such as measured outcomes, ease of use, burden, etc. The objective of this study is to examine the extent of research activity that relied on data logger technologies for manual wheelchair users. We undertook a scoping review of the scientific and gray literature. Five databases were searched from January 1979 to November 2014: Medline, Compendex, CINAHL, EMBASE and Google Scholar. This review retained 104 papers. The selected papers document a wide variety of systems and technologies, measuring a whole range of outcomes. Of all technologies combined, 16.8% were accelerometers installed on the user, 14.8% were magnetic odometers or odometers installed on the wheelchair, 10.2% were accelerometers installed on the wheelchair and 8.67% were heart monitors. So, it is not surprising that the most reported outcomes were distance, speed and acceleration of the wheelchair, and heart rate. In the future, it may be necessary to reach a consensus on what outcomes are important to measure and how. Technological improvements and access to less expensive devices will probably make it possible to easily measure many important outcomes at relatively low cost., Conference paper, Published.
