Project Walk

I am a recently qualified physio in the UK. I am interested in spinal cord injury (SCI) rehab. When I was searching the Internet, I came across Project Walk or the Dardzinski Method. I went to their website and they claim outstanding results in rehab for those with SCI. What I would like to know is how much they are recognised in medical science or physiotherapy. How credential are their claims? Is anybody interested in or practicing this method in the UK? I would be glad if anyone could answer these questions. Thanks.
