This is thinking outside the box ... or head. Dr. Matthew Bromwich of the Children's Hospital of Eastern Ontario has written an iPhone app to help doctors with the Epley maneuver to cure some forms of vertigo. The patient places the iPhone against his or her forehead and the app leads the doctor through the maneuver. Bromwich's first attempt at the app sounded even more fun. With that version, the iPhone hung from the front of a baseball cap the patient wore, and the patient tried to keep a ball centered in a twisting tube by moving their head. Winning the game meant the maneuver had been successfully completed and the vertigo cured.
