Enjoyed the discussion.
You repeatedly mentioned rehabbing the injured part in the context of its normal use. When this is done, the healthy parts pick up the slack for the injured parts and the injured parts recover while being worked in their normal context.
I would have enjoyed hearing your opinions about why using the part in context would enhance healing. I agree that it should be sort of obvious, but your thoughts on the subject would have been interesting. For example, what sort of neurological signalling occurs when an injured part continues to be used as normal, as opposed to being locked in position, or used unnaturally (like the hamstring curl). I thought about something I had heard many years ago that unilateral training of the unbroken arm speeds healing of the the broken, casted arm, presumably because of some sort of neurological signal that gets sent to the broken, casted arm, even though its in a cast.
This seems so obvious, but Im sure you have some deeper thoughts...
