Starting playing after injury

Hi everyone!

I haven't posted in a long time, but now I have an important question to all of you who has experience of injuries due to pianoplaying. This topic is discussed into pieces in many ways, but my question is about going back to practice after a time of recovering.
I have started to study pianoplaying at a school here in Sweden now, the course is one year and I started in august. After a month my right arm felt sore, and if any of you guys remember, I have posted about this problem earlier. The last period of soreness turned out allright, at first I stopped playing totally and when the pain ceised I started slowly and I improved my technique by actively concentrating on my innefficient movements, relaxation and just general focusing to my body´s signals.
However, when I started here I began practicing for much longer periods than usual and neglected my signals of overpracticing. I've now learned a lot about ergonomics etc.

But now my question is: How well do the other hand (or brainhalf?) absorb/learn technique while the healthy one keep on analysing movements and discover easier ways to solv difficult movements??
During this last month (and earlier) I have kept playing - but now with extra extra ergonomic awareness - with my left hand (luckily the repertoire is big). My technique has improved, aswell as my endurance or what I should call it.
I've studied Scriabins prelude and nocturne op.9 nr1 & 2 (both for left hand alone) and I will soon begin with one of the Godowskys Chopin etudes for left hand.
Since learning is to a big extent psycologic (I don't know any better word in english) rather than fysical, how much is "transmitted" to the other hand, and automatised? What progress/lack of progress can I expect when I'll make another try? (A try that hopefully will be the only one I will need)
Bernhard, any facts??

I hope you understand what I mean.
You are all welcome to post all your kowledge about this!
