The Avatar Will See You Now

Medical centers are testing new, friendly ways to reduce the need for office visits by extending their reach into patients’ homes.

Most patients who enter the gym of the San Mateo Medical Center in California are there to work with physical therapists. But a few who had knee replacements are being coached by a digital avatar instead.

The avatar, Molly, interviews them in Spanish or English about the levels of pain they feel as a video guides them through exercises, while the 3-D cameras of a Kinect device measure their movements. Because it’s a pilot project, Paul Carlisle, the director of rehabilitation services, looks on. But the ultimate goal is for the routine to be done from a patient’s home.

“It would change our whole model,” says Carlisle, who is running the trial as the public hospital looks for creative ways to extend the reach of its overtaxed budget and staff. “We don’t want to replace therapists. But in some ways, it does replace the need to have them there all the time.”
