Komissarova, 23, revealed the news on her Instagram account 11 days after undergoing surgery to repair a fracture and dislocation of her T12 vertebra, in which the skier received a metal implant.
She sustained the injury during a training crash as she prepared for the women's skicross event in Sochi, Russia.
"I do not feel the body below the navel," Komissarova wrote. "But I'm strong and I know that someday I just stand on legs!"
Russian President Vladimir Putin visited her in the hospital shortly after the crash.
