MEMPHIS, TN — A pilot program in Memphis is bringing VA closer to meeting what perhaps is the greatest desire for its 42,000 veterans with spinal-cord injuries and disorders: more control of their environment.
This month, VA Memphis will roll out the “autonoME” environmental control unit (ECU) from Accessibility Services Inc., which will enable that spinal-cord unit’s 60 patients to do things such as adjust their beds, call a nurse, use the Internet, select music and make phone calls, even if they can only move their eyes.
As one of the winning programs in the 2011 competition, the environmental-control pilot received funding through the VA Employee Innovation initiative.
According to Charles Brown, director of the VHA Innovation Program, the equipment being tested in Memphis is much more sophisticated than current controls. “Because the equipment can be calibrated for facial recognition, a patient can actually activate and read e-mail, select a TV channel, play a game or select an educational review, just by eye movement,” he said. “If they can just raise their eyebrows, it can track that.”
“We wanted to give our patients more control. Our spinal-cord patients have gone and fought for our country and come back with these terrible injuries. It’s a terrible thing to lie on the bed and not be able to control any aspect of your surroundings. It’s just not good care,” added Sheena House, chief bio-medical engineer at the Memphis VA Medical Center. For five years, House had sought a way to enable veterans with severe spinal cord injuries (SCI) to better control their environment.
While some sophisticated equipment existed for home use, no manufacturer had tackled the challenges of hospitals using different types of beds, a variety of televisions and a range of patient capabilities, according to House. “We had contacted a number of vendors, and no one was willing to tackle the challenges in a hospital environment. We had decided to just get better cabling to make our existing units work more efficiently. The Tampa VA Spinal Cord Unit referred us to Accessibility Services for the cabling, but when they saw our true need, they did everything that we wanted and more.”
The autonoME units offer a variety of ways for SCI patients to interact with the system, including voice activation, sip-and-puff straw usage, head-tracking, eye-pupil movement and single/dual switches. For those with more capability, the devices also have touchscreens. “Sheena wanted a system that allowed vets to control their environment. We thought we could enable them to compute with the same equipment. The unit we developed collaboratively withAssistive Technology Solutions, AM Communications and the Memphis VA allows patients to make adjustments in the room and also get online, send e-mails, use Skype, access Kindle readers and play simple games like chess and solitaire. If they are nonvocal, an integrated augmentative communications device allows them to talk to their physicians, family and friends. The unit takes them into the 21st century,” says Fred Thompson, commercial relations manager at Accessibility Services, based in Florida.

House and Cathlene Wall, a biomedical equipment support specialist at the Memphis VA, talked to patients and nurses to determine patient needs, identify current challenges and work with the development team to create a device that would work with existing equipment and constraints. Most importantly, the team “wanted to give patients a sense of independence during their stay in the hospital. Controlling our surrounding is so basic for us, but it’s a huge thing for them. It’s also a big safety issue here. We want them to be able to call the nurses when they need to. The device restores some of the independence and control they used to have and lost through their injuries,” House explained.
