SCOTTSDALE, AZ -- Six-time Olympic gold medalist swimmer Amy Van Dyken severed her spinal cord in an all-terrain vehicle accident over the weekend, and she told emergency workers she could not move her toes or feel anything touching her legs.
The 41-year-old swimmer, who goes by her married name Amy Van Dyken Rouen, was injured Friday. She was airlifted to a hospital and had surgery to stabilize her spine.
Hospital spokeswoman Alice Giedraitis didn't provide details Monday on Rouen's injuries. She said the swimmer was in good condition Monday afternoon.
A letter from the Van Dyken and Rouen families said she severed her spinal cord at the T11 vertebrae and that the broken vertebrae came within millimeters of rupturing her aorta.
"Amy awoke within hours of surgery acting like her typical spunky, boisterous, ebullient self and has spent the last 24 hours entertaining her family and her medical staff in the ICU," the letter said.
A report by the Show Low Police Department said the ATV that Rouen was driving hit a curb in a restaurant parking lot and sent her over a drop-off of between 5 and 7 feet.
Rouen was found lying on the ground next to the ATV. She was strapped to a backboard and airlifted to Scottsdale Healthcare Osborn Medical Center.
A witness said he saw Rouen launch over the curb and found her unresponsive when he arrived on the scene, the report said. Rouen was not wearing a helmet at the time.
Her husband, former Denver Broncos punter Tom Rouen, told police officers he had changed the throttle mechanism on the ATV from a thumb accelerator to a twist accelerator a few days before the accident, though wasn't sure if it was a factor in the accident.
He said his wife had not been drinking alcohol that evening.
"So hard hearing about (Amy) and her horrific accident," fellow American swimmer Missy Franklin said on Twitter. "I am praying continually for you and your family."
Rouen starred at the 1996 Atlanta Olympics, where she became the first U.S. female athlete to win four gold medals in a single games. She captured the 50-meter freestyle and 100 butterfly and also competed on the winning relay teams in the 400 free and 400 medley.
Four years later at Sydney, she added two more golds in the 400 free and 400 medley relays before retiring from competition.
In 2003, she was among numerous prominent athletes who testified before a grand jury investigating the BALCO doping scandal. Rouen never tested positive for performance-enhancing drugs during her career.
"The USA Swimming family is devastated to learn of Amy Van Dyken's unfortunate accident this weekend," the organization said in a statement. "We're happy to hear that she escaped and is now in great care. That she is already 'acting like her typical spunky, boisterous, ebullient self' shows she's on a great path."
"Amy is a champion who has proven throughout her life that she is a fighter who takes on challenges and comes out on top. We know Amy will tackle her rehabilitation with vigor and be back on her feet sooner rather than later," it said.
Rouen grew up in Denver and became a world-class swimmer despite suffering from asthma as a child and into adulthood. She swam two years at the University of Arizona and transferred to Colorado State University, where she broke the U.S. record in the 50-yard freestyle during the 1994 NCAA championships.
She has worked in television and radio after retiring from competitive swimming, and currently lives in the Phoenix area with her husband.
"Our thoughts and prayers are with Amy during this difficult time, but we know she'll fight her way back to health," Arizona swimming and diving coach Rick DeMont said in a statement. "Her drive and determination helped her become one of swimming's all-time greats and we know she'll use those same attributes as she sets out on the path to recovery."
