Beth appeared on the third series of The Jump, which saw celebrities take on a range of winter sports including the ski jump.
But she was one of many contestants who was left injured, suffering a fractured vertebrae while taking part in the 2016 season.
Three years on, Beth has announced she is now pursuing legal action after failing to come to a settlement with the programme makers.
"It's been a long journey and my recovery is still ongoing. I'm not sure I'll ever be 100% again," said Beth in a statement today (via Sky News).
She explained: "The effects of my accident still interrupt my daily life, and, aside from the severe physical injuries at the start, the hardest part of the recovery process has been the psychological element, dealing with and processing the whole accident and the aftermath of what happened.
"It's disappointing that we have had to seek court proceedings as we had hoped the makers of the programme might be willing to work with us to settle the case.
"But I just want to make sure that there is full accountability for people involved in creating shows like this and to help prevent others having to go through what I have for the past three years."
Beth's injury required "serious surgery on her spinal cord", said her lawyer Demetrius Danas.
He added: "She has had to put many parts of her life and career on hold and, while Beth is making a good recovery, she still cannot do many of the things she previously could as an elite athlete and may never fully recover.
"Despite attempts to settle the legal case amicably, the defendants involved in making The Jump have so far denied any liability for her injuries and we have been left with no choice but to issue court proceedings as we seek to resolve the case."
A statement from production company Twofour said: "This matter is being dealt with by our insurers and we are unable to comment as the claim is ongoing."
The Jump was eventually dropped by Channel 4 in 2017 after four series.
