This interview makes a good point. It's not just about walking, the issue is much more complex. My personal thought is that this advancement has amazing potential for the future, but I can understand completely, especially AS an ambulatory quad, why these ladies aren't jumping at the bit to partake in this. If this discovery meant perfect healthy walking and function, sure. However, as they say, this current study is not there yet. For these women, and a lot of other people I'm certain, the most important thing is quality of life. I can tell you that walking with permanent limp, tone, spasticity and pain, is not ideal; even though I'm technically closer to "normal". And I have mentioned that I do wish I'd accepted the help of a chair, and may even begin to use one now. Being visibly 'closer to normal' is not the goal. Having the best quality of life by reducing pain and fatigue as well as finding ways to ensure independence is paramount for a spinal cord injured person. Being able to stand up and take a few steps does not equal that.
And besides the physical act of walking, there is a whole lot more involved when it comes to SCI. Bowel and bladder function, sexual function, loss of sensation, hyper sensation, pain (nerve and musculoskeletal), to name a few.
Still, this phenomenal advancement does seem to promise help is on the way, even if it's not perfect, yet. It does seem to be a remarkable 'step' in the right direction. (haha, so punny :p)
And I must admit that I do hope with further studies, tests, and trials, we WILL find in a true cure for SCI.
