I find this part most interesting:
"Three participants (2, 7, 8) regained motor control. i.e., converted to AIS C or D, at the 1-month examination. Other three (4, 5, 6) converted to grade C after 3 months. In the present study we observed that, in contrast to the expected baseline conversion of 15%, 75% (6/8) of the participants regained voluntary motor control after polylaminin treatment. If we consider only those participants that reached discharge, the proportion increases to 100% (6/6)."
Sometimes drug and medical device companies will gag patients with non-disparagement agreements, while letting the success stories post freely on social media to promote their product/procedure/etc.
A good friend of mine spent years doing research at Caltech in basically trying to bridge the severed part of the spinal column with electrodes. In mice that is.
The department got lots of $ from the Christopher & Dana Reeve Foundation to help them in said research.
