Paralyzed Man Walks Naturally After Implants

[Drashner1]

I haven't seen real life examples of this, but OA includes the concept of Neuropsychological Engineering, which by Y11k is at a point where people can change their mental structures/wants/needs/desires more or less at will. Potentially, early forms of this technology - and/or early timeline developments in Direct Neural Interface technologies could have operated via implants specialized to intervene in ways such as you're indicating here.

My 2c worth,
