Her coach, Liz Kincaid, said, "Imogen was vaulting with a wrist support on and noticed during her hurdle step that the support had come undone.

2009

Cairns decided to return to training in 2009. She said, "I thought about quitting because I was out for so long. I put on a bit of weight and got my social life back and I thought, 'This is it.' But when your whole life has been gymnastics, you do miss it. I thought, 'I have nothing to lose if I try to come back.' It was just pure determination. I wanted to do it."^[14]

Having been through the highs of the Olympics and lows of injury, I can honestly say I now take things step by step. I learn from successes and setbacks, and put these to good use. I think I've matured, and I set myself personal goals."^[17]

She contributed an all-around score of 53.500 towards the English team's second-place finish.^[18] In the all-around final, she placed fourth with a score of 54.650. "One year ago, I didn't think I'd be able to train again," she said. "I think I was only just getting back to walking. Gymnastics just wasn't in the equation until my surgeon said that anything I did to my feet couldn't make them worse—so I decided to go for it again."^[19] In event finals, Cairns placed first on vault, scoring 13.775; eighth on balance beam, scoring 11.950; and first on floor, scoring 14.200.^[20] After the vault final, she said, "The gold today perhaps means more this time around, having been injured in both feet after the Beijing Olympics and being off for 15 months."^[21]
