Wiiitis — pronounced “wee-eye-tis” — is the latest ailment to develop from the video game era, beginning with Space Invaders’ wrist in 1981, which was caused by the repeated button mashing required by the popular arcade game.
In 1990, a Wisconsin doctor characterized the thumb soreness brought on by pushing the buttons on a controller as “Nintendinitis” after it affected a 35-year-old woman who played a Nintendo game without interruption for five hours.
