As I don't really use that language, "mapping the hand," I can't really answer your question.
However for a few more clues, please visit this page
and scroll down to the 7th video you see, titled, "Reiko Miyazaki finger rolling skeletal therapy variation." This shows a typical therapeutic approach for a dystonia. Reiko had tendonitis, not dystonia, but the approach is similar.
Good luck!
