Two links with two angles for SCI research:
One article describes the "Neuro-Spinal Scaffold," an innovation of InVivo Therapeutics. Designed specifically for thoracic injuries and to be implanted immediately after the injury, a scaffold inserted inside the spinal cord apparently works against the development of harmful scar tissue.
The second article is about a limited stimulation treatment study conducted at the BioMag Laboratory (Helsinki University Hospital). Successful ongoing application suggests that it may help with regaining movement, even two years after the injury.
A big point here is that the different methods involve very different time periods. Scaffolding is being tried soon after the injury. Stimulation, much later. And both show some promise - hopefully similar updates to come soon.
