Webster's New World Dictionary describes the word trampoline as "a net of strong canvas stretched tightly on a frame, used by acrobats, as in a circus, for performing various feats of tumbling." In years past, when this definition was true, trampolinists were rare and injuries on the trampoline even more rare. The average physician treated trampoline injuries as often as he treated tiger bites and falls from the high wire.
In recent years, the public has joined the acrobatic circus, and use of the trampoline on a mass basis has steadily gained in momentum. Within the past few months it has become a minor national craze. Along with this sudden rise in popularity, disquieting reports of injuries resulting from use of the trampoline have begun to appear in the popular press. Some reports were of serious injury and even death.
