This is the adorable moment twin boys with cerebral palsy were left in hysterics when riding a roller coaster.

Video shows Isaac and Sawyer Jenson, four, laughing uncontrollably on the BomBora roller coaster at the Lagoon Amusement Park in Farmington, Utah, USA.

Isaac and Sawyer have limited independent mobility so they love play that involves movement such bouncing on yoga balls or going down fast slides.

Julia, a stay-at-home mum from Riverton, Utah, said: "We think it gives them a sense of 'flying' or independent movement they cannot feel on their own."

"It is a completely new feeling for them."

"It's pure joy and freedom when they're whipping around on a ride with the wind in their hair."

"My husband and I often see them unable to participate in common activities with their peers because of their disability."

"So seeing them like this makes us overjoyed."

The twins had ridden smaller roller coasters before and loved it so Julia, 26, and husband Seth, 29, decided to up the ante.

Julia said: "We first took them on a very tiny baby coaster that literal babies can ride and they loved it."

"There was laughter and giggles right away and this particular park has a huge section for kids, so that was only the beginning."

"We kept going bigger and faster when it comes to the ride intensity until we completely maxed out their height for attractions."

"For them, the bigger and faster the coaster is, the happier they are!"
