While Nassar has been accused of by more than 130 women of sexually abusive behavior, the case in Ingham County stems from charges that he inserted ungloved fingers into eight women's vaginas and rectums at MSU's sports-medicine clinic when they were under the age of 16, according to The Detroit News.
Douglas, a three-time Olympic gold medalist, said she didn't disclose his abuse earlier because "for years we were conditioned to stay silent and honestly some things were very painful".
He worked for USA Gymnastics, the organisation that prepares gymnasts to compete in the Olympics.
Nassar faces 25 to 40 years in prison on each count.

On Wednesday, Larry Nassar, a former USA Gymnastics team doctor, pleaded guilty to seven counts of first-degree criminal sexual assault, six of which applied to girls 15 or younger. "Larry is digusting. Larry is a MONSTER not a doctor", she wrote.
Douglas in a separate tweet later apologized for "coming off like I don't stand alongside my teammates".
Larry Nassar, 54, admitted to sexually assaulting at least seven girls, all but one of whom are gymnasts, while he was working as a physician for USA Gymnastics and Michigan State University. Nassar had been charged with 22 counts of first-degree criminal sexual conduct and 11 counts of third-degree criminal sexual conduct at the state level.
