The number of bounce-house related injuries have increased 15-fold from 1990 to 2010, according to nationwide study, LA Times reports.
The number of bounce-house related emergency room treatments has increased along with the popularity of the bounce-houses, from fewer than 1,000 in 1990 to almost 11,000 in 2010.
With these numbers, in 2010 approximately 31 children were admitted each day at a rate of one injury every 46 minutes, LA Times said.
Overall, the researchers found 64,657 bounce-house related injuries have been reported from 1990 to 2010.
The researchers said that these findings show the need for guidelines for safer bounce-house usage and improvements on the design of the bounce-houses to make them safer for children.
