COLUMBUS -- Injuries related to those big bounce houses are on the rise. That's according to new research out of Nationwide Children's Hospital in Columbus.

The study showed since 1990, nearly 65,000 children went to the Emergency Room after getting hurt on an inflatable bouncer.

Between 2008 and 2010 the number of child injuries more than doubled to an average of 31 a day. Broken bones and sprains of the arms and legs were the most common injuries.

Now experts are calling for improved safety standards.
