Multiple clinical trial participants who have severe spinal injuries were able to stand, walk, and perform specific activities after just one day of using an implant surgically embedded in their spines.
Two of the implanted valves lasted a full year as the animals matured into adult sheep, demonstrating that it might be possible to treat children with valve replacements that grow along with them.
The effects of the therapy in a small group of patients were long-lasting, researchers say, adding to evidence that the approach works for treatment-resistant depression.
