She continued to emphasize the severity of her injury when she was interviewed at her home by agents from the U.S. Department of Veterans Affairs and the Social Security Administration in June 2015.
"So you have no use of your right hand whatsoever?" one of the agents asked, according to a transcript of the interview.
"No," she replied.
"OK, we have a slight problem, all right?" the agent said.
The agents told Riedling that she had been under investigation, and they had surveillance video of her using her hand during a trip to Disney World with her daughter, court documents said.
They said Riedling had been recorded numerous times using her hand as part of a "massive, massive amount of investigation," the transcript said.
Riedling gave the agents a statement in which she admitted that she had "stated I was more disabled that I was."
"I know that this is completely wrong," she wrote.
Riedling was indicted last February on charges of theft of government property and making a false statement.
Riedling, who will be sentenced on April 11, faces up to 15 years in prison.
