Here is a flowchart used to guide recovery of walking after stroke...
Boy, that's complicated!
How do we learn how to walk in the first place- as infants? Does it involve "treatments" that span from "Task Specific Training" to orthotics?
Stroke recovery is hurt by complexity. When rehab options become too complicated the stroke survivor is separated from their own recovery because they don't know what to do.
Forget survivors for the moment... At some point stroke recovery can become so complicated that even clinicians don't understand it. Or they don't understand the technology in the complicated system because they never interface with that complicated technology.
Have a look at the algorithm above. I would argue the whole thing is not only way too complicated, it's also incorrect.
I would like to rewrite the entire algorithm like this...
Post-stroke ambulation most benefits from task specific training. Translation: Walking more improves walking.
