title: Expanding medical horizons.
abstract: When I was completing my orthopedic surgery residency in the early 1980s, a slogan on a T-shirt caught my attention: "Exercise Is Medicine." The idea made great sense to me, especially considering its rich tradition going back to Hippocrates. At that time, however, the clinical role for exercise as medicine was minimally defined.
