title: Using Health Games for Physical Therapy: An Interview with Ernie Medina, DrPH.
abstract: Dictionary.com defines catalyst as "a person or thing that precipitates an event or change." That certainly defines Ernie Medina, PhD, the subject of this month's Games for Health Journal interview. Dr. Medina is a blithe force in the use of health games, and his enthusiasm, creativity, commitment, and good nature are exciting and engaging. And, the catalytic role he is developing provides the much-needed link between patients who can benefit from health games and doctors looking for effective, high-compliance means for rehabilitation.
