FAIRFAX, Va. (AP) - Andrew Carle, an assistant professor at George Mason University and a consultant on senior housing issues, is always looking for new technology to improve the lives of the elderly. He’s even coined a term for his life’s work: “nana technology.”

“I’ve always tried to close the great divide between geeks and grans,” said Carle, who’s also the founding director of GMU’s program in senior housing administration.

So when he came across a shoe in 2007 with a Global Positioning System device embedded in the sole - an innovation aimed at parents concerned about their kids disappearing - he had an idea. Why not use the technology to develop a shoe for senior citizens? It could be a lifesaver for people with Alzheimer’s disease and other dementia patients while easing caregivers’ fears that they’ll wander away.

Carle met with Patrick Bertagna, chief executive of GTX, the Los Angeles-based maker of the shoe. “It just really touched us,” Bertagna said of his meeting with Carle. “I brought in a whole management team to shift our focus.”

By late 2011, a new GPS-equipped shoe was ready for people with a variety of cognitive disorders, including traumatic brain injury and autism. Word spread quickly, and in 2012, a Swedish science museum named the shoe one of the “Top 100 Innovations of Mankind,” alongside the telephone and the Internet.

Now, Carle and GTX are taking their nana technology a step further. They’ve developed insoles with an embedded GPS device so that the technology can be easily moved between pairs of shoes. The “Smart Soles” are being tested by groups that work with dementia patients, and Carle said the soles are scheduled to be released this summer.

The GPS shoe and insole have all sorts of potential ramifications, and the word is spreading. During Super Bowl week, Carle met with the NFL Retired Players Association, many of whose members are believed at risk of chronic traumatic encephalopathy, a degenerative brain disease.

Carle is also reaching out to veterans groups, some of whose members suffered traumatic brain injuries, to autism groups and to law enforcement agencies. Police and sheriff’s departments are often called on to conduct extensive searches for missing seniors who are in danger of dying of exposure or dehydration.

“You’ve got 5 million people with Alzheimer’s in this country,” Carle said, “and that’s going to quadruple. You’re going to have municipalities who do nothing but search and rescue for local seniors all day.”

The International Association of Chiefs of Police launched an Alzheimer’s initiative for police departments several years ago because dementia patients are a serious concern for law enforcement. Amanda Burstein, director of the IACP initiative, said GPS-equipped devices such as the GTX shoe are “part of our options for law enforcement in our classroom training.”

Burstein emphasized, however, that the shoe didn’t solve the problem.

When such devices produce quick results, “there’s obviously a huge resource savings,” Burstein said. “But it’s limited to those who can afford it, take care of it and are monitoring it.”

Fairfax County Sheriff Stacey Kincaid expressed similar reservations. She cited the cost - $299 per pair, plus $20 to $40 a month for a cellular service plan - and the need to charge the GPS device daily. “It’s not so easy as putting on a shoe and calling it a day,” Kincaid said.

In Project Lifesaver, the program Kincaid’s office uses now at minimal cost, deputies make regular visits to replace the batteries in the radio-tracking bracelet.

Carle said the GPS shoe or insole is a substantial improvement over the Project Lifesaver program because it doesn’t require a bracelet, which many dementia patients dislike, and it doesn’t require law enforcement involvement. It also uses GPS technology instead of radio frequency identification-based technology that requires a searcher to come within 400 yards of the subject.
