Trampolines for home use have become common in Finland during the past ten years, being especially favored by children.Trampoline jumping is beneficial and constructive physical exercise, but poses a significant risk for injuries. The most common injuries include sprains and strains. During summertime, trampoline injuries account for as many as 13% of children's accidents requiring hospital care. Fractures are by far the most common trampoline injuries requiring hospital care. Injuries can be prevented by using safety nets. Only one child at a time is allowed to jump on the trampoline.
