Clarke, whose side clash with Eoin Morgan's men for the first time in the ODI series on Friday, said that his problem is "manageable" and would not be focusing his preparation any differently.
"I don't know how many one-day games and Test matches I have played throughout my career but I have managed to stay on the park for the majority of those," he told Sky Sports News.
"It's obviously manageable and I feel as fit and strong as I have been throughout my career so I don't see why I cannot continue to manage it and carry on playing in both forms of the game.
"I don't know what is perfect preparation for my back but I think I can manage my body as well as I have done in the past and that will allow me to continue playing both forms."
Australia lost the Ashes Test series 3-0.
