A former member of the US national team has become the latest gymnast to file a lawsuit over sexual abuse by imprisoned former sports doctor Larry Nassar, alleging USA Gymnastics, the US Olympic Committee and the husband-and-wife duo who coached America's top female gymnasts for three decades failed to protect her and other athletes.

Sabrina Vega, who was on the team that won a gold medal at the 2011 World Championships, alleges the organisations along with Bela and Martha Karolyi ignored signs about Nassar's behaviour or should have known he posed a risk to the gymnasts he treated.

Here's some of what Larry Nassar's 160 victims had to say about the disgraced former doctor.

Romanian-born Bela Karolyi famously coached superstar Nadia Comaneci, before defecting to the US in the 1980s.

He and his wife Martha became coaches to the US National team, leading to the success of generations of gymnasts including Mary Lou Retton, Dominique Moceanu and Kerri Strug.

Vega alleges that during medical treatments, Nassar molested her hundreds of times from 2008, when she was 12 years old, until 2012, during competitions and while she trained at the Karolyi Ranch.

The ranch is outside of Huntsville, about 110 kilometres north of Houston. Vega's lawsuit was filed in state district court in Huntsville.

"I have struggled to cope with the effects of the repeated abuse I suffered at the hands of Dr Nassar. USA Gymnastics, the USOC and the Karolyis failed to protect me and the other athletes in their care and I believe they should be held accountable," the 22-year-old Vega said in a statement.

Vega, who now competes as a gymnast for the University of Georgia, said Nassar's abuse has caused her depression, panic attacks and anxiety, which have become worse as Nassar's case has become widely publicised.

In a statement, USA Gymnastics said it did not comment on pending litigation but the organisation was, "committed to creating a culture that empowers and supports our athletes and focuses on our highest priority, which is the safety and wellbeing of our athletes".

US Olympic Committee spokesman Patrick Sandusky said in a statement Nassar's "reprehensible behaviour" had no place, "in our Olympic and Paralympic community" and that the organisation had, "made significant progress to strengthen protections for athletes, and we recognise that our work is never done".

Karolyis seek $1 million in damages

An attorney for the Karolyis did not immediately reply to emails or calls seeking comment.

The Houston Chronicle reported the Karolyis had quietly filed a lawsuit last month in Huntsville against USA Gymnastics and the US Olympic Committee, seeking more than $1 million in damages.

The lawsuit says the couple did not know about Nassar's "reprehensible conduct" and would have reported it if there had been any suspicions about him.

In an interview with "Dateline NBC" that aired last month, Martha Karolyi said she felt for Nassar's victims but that she did not believe she should be held responsible for his actions.

Vega's lawsuit is the third to be filed against the Karolyis. The other two were filed in California.

More than 250 women and girls say Nassar, who worked for USA Gymnastics and Michigan State University, sexually assaulted them under the guise of treatment. He's now serving up to 175 years in prison for molesting women and girls and possessing child pornography.

Several gymnasts have said Nassar abused them at the ranch, which served as the training ground for US women's gymnastics.

Vega alleges in her suit the Karolyis allowed Nassar to enter the cabins of female gymnasts alone and unsupervised to perform his training techniques.

The ranch is being investigated by the Texas Rangers and the Walker County Sheriff's Office. USA Gymnastics cut ties with the ranch in January.

Vega's lawsuit is the second filed in Texas in the last few weeks related to the abuse scandal.

Last month, Rebecca Whitehurst, a former Texas gymnast who had been a member of the USA Gymnastics team, filed a suit in Houston against USA Gymnastics, alleging Nassar abused her in 1996 when she was 15 years old.
