Volume 5, Issue 1, March/April, Spring 2006
As 2006 begins, the investigators and staff at HERL are exploring new opportunities to expand upon work begun just last year, conduct research at a new event, and analyze where we are going in the future.
This year we received funding to conduct 4 more of our popular “State of the Science” workshops with Walter Reed Army Medical Center (see “new grants,” page 5). These free workshops are open to military and VA personnel as well as patients and their families. Medical and rehab personnel may obtain Continuing Medical Education (CME) or Continuing Education Units (CEU) credits by attending. This year’s first workshop will address Sensory Impairment on April 21 (registration deadline is April 14) and the second is on Assistive Technology Devices on May 26, 2006 (registration deadline is on May 19). The SoS workshops are held at Walter Reed Army Medical Center (WRAMC) and participants can register and view the workshop agendas at our website, www.herlpitt.org. Workshop sponsors include the University of Pittsburgh Departments of Physical Medicine and Rehabilitation and Rehabilitation Science and Technology and the Center for Continuing Education in the Health Sciences. Subsequent workshops will be announced later this year...continue to check the HERL website for updates.
We held our yearly Advisory Board Meeting on March 27-28. The purpose of this meeting is to objectively evaluate our performance. Our 2006 advisory board was comprised of representatives from some of our collaborating institutions: Tom Stripling (Paralyzed Veterans of America), LTC Paul Pasquina, M.D. (Walter Reed Army Medical Center), Carmen DiGiovine, Ph.D. (University of Illinois at Chicago), Jim Osborn (Carnegie Mellon University), Melissa Murray (Hiram G. Andrews Center), Attila Domos (a longtime friend of the lab and participant in HERL research studies), Ron Boninger (Three Rivers Holdings, LLC) , Mike McCue, Ph.D. (University of Pittsburgh Department of Rehab Science and Technology), and Charles Sfeir, DDS, Ph.D. (University of Pittsburgh/McGowan Institute of Regenerative Medicine.) The panel provided valuable insight as well as research and management suggestions to help take HERL into the future.
For the first time, HERL had the opportunity to attend and conduct research at the Disabled American Veterans (DAV)/VA Winter Sports Clinic from April 2-7 at Snowmass Village, CO (see “new grants,” page 5). Also sponsored by the Department of Veterans Affairs, the DAV winter sports clinic promotes rehabilitation by instructing disabled veterans in adaptive skiing, and providing an introduction to other adaptive activities and sports.
Researchers from WRAMC and Madigan Army Hospital joined HERL in recruiting 97 new participants for studies examining physical activity and quality of life among veterans and military personnel who use wheelchairs and prosthetics. As the summer approaches, so do two important annual HERL events: the Rehab Engineering and Assistive Technology Society of North America (RESNA) Conference and the National Veterans Wheelchair Games. This year’s NVWGs are being held in Anchorage, Alaska and a team of HERL investigators will be conducting studies there

Erik Wolf, MS, Jonathan Pearlman, MS, Rory A. Cooper, PhD, Shirley G. Fitzgerald, PhD, Annmarie Kelleher, MS, Diane M. Collins, PhD, Michael L. Boninger, MD, and Rosemarie Cooper, MPT
Full article published in Disability and Rehabilitation, pp. 1443-1449, Vol. 27, No. 23, December 2005.
Purpose of Work: According to the International Standards Organization 2631-1 standard on human vibration, individuals in a seated position are at risk of injury due to whole-body vibrations when exposed for long periods of time. Wheelchair users fit this description perfectly, however little research has been conducted to evaluate the amount of vibration transmitted to a wheelchair user. The purpose of this study was to evaluate the amount of vibrations transmitted to the user during travel of different sidewalk surfaces.
Procedures: Ten unimpaired subjects propelled over nine different sidewalk surfaces in a manual wheelchair and a powered wheelchair. One surface was a standard poured concrete sidewalk and each of the other eight was a concrete or brick paver of varying bevels.
Results: For the manual wheelchair, three surfaces resulted in higher vibration exposure than the standard surface; the 8mm bevel surface in a 90 degree herringbone pattern, and the two 6mm bevel surfaces. For the power wheelchair, two surfaces resulted in higher vibration exposure than the standard poured concrete the 8mm bevel surface and one of the 6mm bevel surfaces. Relevance to Wheelchair Users: Using smaller bevels on pavers exposes individuals using wheelchairs to less vibration. Also, pavers installed in a 90 degree herringbone pattern produced lower vibration exposures. It is recommended that only pavers of 6 mm bevel or less be used, with a 90 degree herringbone pattern. It is possible to provide sidewalks that are made from concrete or brick pavers that are also safe for wheelchair users.

Evaluation of the Safety and Durability of Low-Cost Nonprogrammable
Electric Powered Wheelchairs
Jonathan Pearlman, MS, Rory Cooper, Ph.D., Jaideep Karnawat, Rosemarie Cooper, MPT, Michael L. Boninger, M.D., Full article published in Archives of Physical Medicine and Rehabilitation, pp. 2361-2370, Vol. 86, No. 12, December 2005.
Purpose of the work. To control rising healthcare costs, insurance companies may try to reimburse for lower-cost assistive technology, such as non-programmable electric powered wheelchairs (EPWs). With these lower-cost alternatives, it is important to make sure the devices function safely and effectively. Subjects/Procedures: We performed ANSI/RESNA wheelchair standards testing protocols on 12 selected low-cost non-programmable EPWs (3 of each of four models) to measure durability and performance of the devices.
Results: We found that 9 out of 12 of these devices did not fulfill the required durability standards. Additionally, other safety issues, such as motor overheating, could adversely affect the performance of the device.
Relevance to Wheelchair Users: To ensure the safety and maximum function of the user, high-quality EPWs must be available. The low-cost non-programmable EPWs we tested did not meet these standards, and EPW users should investigate the devices available to them.

The Development and Preliminary Evaluation of a Training Device for Wheelchair Users: The GAMEWheels System
Shirley G. Fitzgerald, PhD; Rory A. Cooper, PhD; Emily Zipfel, BFA; Donald M. Spaeth, PhD, ATP; Jeremy Puhlman, BSE; Annmarie Kelleher, MS, OTR/L, ATP; Rosemarie Cooper, MPT, ATP; Songfeng Guo, PhD
Full article published in Disability and Rehabilitation: Assistive Technology, pp. 129-139, Vol. 1, No. 1-2, January-June 2006.
Purpose of the Work. Training of appropriate wheelchair propulsion methods may be beneficial to manual wheelchair users by reducing pain and improving quality of life. This study involved the development and initial user testing of a haptic device, the GAMEWheels System, which combines wheelchair propulsion training and computer game play.
Subject/Procedures. Two separate models of GAMEWheels were developed: a GAMEWheels Clinical and a GAMEWheels Trainer. To verify and compare the practicality and functionality of the two GAMEWheels systems, several focus groups were conducted: first to determine whether the systems could be set-up using different types of instructional materials and second to determine if the systems could be taught to novice users. In the first focus group, three subjects independently used both systems with the aid of instructional materials. Set up time was recorded and subjects completed a questionnaire to provide feedback on 1) ease of assembly 2) overall impression of assembly process 3) level of frustration during assembly and 4) usefulness of instructional materials. Open-ended questions probed subjects’ thoughts on how the device could be improved. In the second focus group, three experts each taught two novice subjects how to use the devices. The subjects then used the devices and responded to the questionnaire.
Results. Subjects’ overall impressions of the systems were that they were ‘fun’ to play. Suggestions were raised to improve the design, which have been incorporated into further refinement of the GAMEWheels systems. The trainer system was viewed more favorably than the clinical system. Subjects gave higher ratings of ease of learning and operating, more positive overall impressions, higher rating of perceived fun, and lower levels of reported frustration than with the clinical system.
Relevance to Wheelchair Users. For manual wheelchair users, use of their upper extremities is crucial to achieving and maintaining independence, both in and out of the home. Training individuals to propel a wheelchair in an appropriate manner could significantly reduce upper limb pain and injury. This research provides a technology solution to help train wheelchair users in appropriate propulsion techniques both in a clinical and a home setting. The results of focus group testing are used to improve product designs which will be transferred to industry and developed into marketable products.

Towards the Development of an Effective Technology Transfer Model of Wheelchairs to Developing Countries
Jon Pearlman, MS, Rory Cooper, Ph.D., Emily Zipfel, BFA, Rosemarie Cooper, MPT, Mark McCartney
Full article published in Disability and Rehabilitation: Assistive Technology, pp. 103-110, Vol. 1, No. 1-2, January-June 2006.
Purpose of the work. In low-income countries, there is a tremendous need for wheelchairs (WC) to help people participate more fully in society, and live more independently. Developing a model to understand the factors that affect WC technology transfer to these countries will help streamline the process.
Subjects/Procedures: We reviewed pertinent literature and used personal experiences to develop a preliminary model of the factors affecting WC technology transfer to these countries.
Results. We developed a model which uses four characteristics (Input, Sustainability, Appropriateness, and Impact) to compare four tech-transfer models (Charitable, Workshop, Manufacturing, and Globalization).
Relevance to Wheelchair Users. Wheelchair users around the world require technology that meets their needs, and can maximize their potential to be part of their society. Understanding the process to both develop and deliver WCs to these individuals works toward this goal.

Dr. Rory Cooper Delivers Inaugural Address at Pitt
On Tuesday, March 28, 2006, Dr. Rory Cooper gave his inaugural lecture to commemorate his official induction as FISA/PVA Endowed Chair and Distinguished Professor in the Department of Rehabilitation Science and Technology at the University of Pittsburgh. The prestigious ceremony was hosted by University of Pittsburgh Provost James V. Maher, who in his introduction praised Dr. Cooper highly for his numerous achievements in the fields of assistive technology research and academia. Dr. Maher presented Dr. Cooper with a Medal of Office, noting that his title was a unique one within the university.
Dr. Cooper's lecture was entitled, "Eat
your own Dog Food: Participatory Action Design," referencing an expression used
in engineering design. "It's really the idea that you shouldn't get other people
to use your technology, your ideas or your devices before you'd use them
yourself. And it's kind of put in that derogatory form of 'Eat Your Own Dog
Food' because most of what we do the first time is unsuccessful. So it's kind of
another way for engineers to say to learn from your own mistakes before you
impose them on others," Cooper explained.
During his speech, Dr. Cooper shared much of his personal history that has
shaped him into the successful researcher he is today, from his first
experiences using a wheelchair, to his career in wheelchair racing, to his early
attempts at designing wheelchairs. He outlined the evolution of his work,
thanking many of his colleagues, co workers, mentors, and students for
contributing to his successes along the way. "It's not an individual effort. It
takes a group working together," said Cooper.

You have to be tough to succeed in the exciting but sometimes violent and aggressive sport of quad rugby. On the Pittsburgh Steelwheelers Rugby team, Rachel Cowan is the only woman on a team with 12 men. Regularly she comes to work with prominent and scary-looking bruises and scrapes, usually shrugging them off if anyone mentions them.
This is Rachel’s third year playing with the Steelwheelers; this year she received a sportsmanship award at the 2006 United States Quad Rugby Association (USQRA) Heartland Sectional Playoffs on March 17-19, 2006 in Montgomery, AL. She received the same honor in January 2005 at the USQRA’s 5th annual “Knock and Roll” Tournament in Jupiter, FL.
Rachel came to HERL from North Carolina in 2003 in pursuit of a Ph.D. in Rehabilitation Science and Technology. She holds a BS in Physical Education from the University of North Carolina (2000) and an MS in Health & Exercise Science from Wake Forest University (2003). Rachel works under the mentorship of Dr. Michael Boninger, primarily in the Biomechanics and Neuromotor Control Laboratory, evaluating wheelchair propulsion techniques. Rachel is a key member of the SmartWheeluser’s group, which develops clinically relevant protocols and standards of use for the SmartWheel, a wheelchair propulsion measurement instrument developed at HERL. She is also a Integrative Graduate Education and Research Traineeship (IGERT) student. The IGERT program seeks to train PhD scientists and engineers in Assistive Technology at the University of Pittsburgh and Carnegie Mellon University. Only 4-6 HERL grad students are supported by the IGERT each year.
When Rachel is not working hard she is playing hard. She plays basketball on the Steel City Starz, lifts weights 3 times a week and does cardiovascular workouts 4-5 times a week in addition to playing rugby. This summer she also plans to add adaptive rowing to her schedule.
Upon completion of her PhD, Rachel hopes to become a Professor concentrating in biomechanics/human movement. “I like teaching,” she noted.
