The New Zealander has been in hospital since sustaining the life-altering injury during the Warriors' Premiership defeat to Saracens on January 4.
Fatialofa was diagnosed with a spinal contusion and had surgery to alleviate the pressure on his spinal cord.
The operation was a success and the 27-year-old had to spend two weeks in intensive care at St Mary's Hospital in London before being transferred to Stoke Mandeville Hospital in Buckinghamshire.
Fatialofa's wife Tatiana has now provided an update on the former Hurricanes forward's progress, revealing that he is defying the expectations of medical professionals by already walking unaided.
"You're witnessing a miracle that even medical professionals can't explain," Tatiana Fatialofa posted on Instagram alongside a video of him walking. "They are so shook by his progress given his critical level of injury.
"He was literally paralysed from the neck down just 10 weeks ago and currently spinal cord injuries do not have a clinical cure, but my amazing husband is proof that god is never limited to human wisdom. So so so thankful."
Worcester's home game with Harlequins had been due to act as a fundraiser for Fatialofa, but the match that was scheduled to take place on April 11 has been postponed due to the ongoing coronavirus outbreak.
