"As best we can tell, the addition of safety nets and padding has actually not changed the injuries we have seen," said Dr. Susannah Briskin, a sports medicine specialist who helped draft the new statement.
It's estimated that the number of trampoline injuries nationwide has been dropping - from 111,851 cases treated at ERs in 2004, to 97,908 in 2009. But that doesn't necessarily mean the devices have become any less dangerous, Briskin told Reuters Health.
"Even though there has been a decrease in injuries," she said, "I caution people against taking that too literally because the number of trampolines has also decreased."
The actual risk of hurting yourself if you step onto a trampoline is not clear, Briskin added, because there are no good data on national exposure. The rate of hospitalization due to the injuries is about three percent.
Mark Publicover, founder and president of JumpSport Inc, a trampoline manufacturer in San Jose, California, scoffed at the AAP's recommendations.
He said he invented a safety net that encircles the trampoline and cuts the number of injuries by half. And, he added, if parents ban trampolines, their children might start climbing trees, using swings or skateboards, for instance.
"If you look at all those activities, a safety-enclosed trampoline is safer by hours of use," Publicover told Reuters Health. "When they say, 'Don't use trampolines with a safety enclosure,' they are going to increase the number of injuries."
