I am a physiotherapist doing further study with the aim of investigating
stress # in the ribs of rowers. I am interested in looking at the
movements of the scapula during the rowing stroke, primarily on the concept
ergometer at the moment, and not
sure how to trace the path of the scapula as it is so mobile under the
overlying skin. It should be a noninvasive method if possible. I can do
it in static positions throughout the cycle but not dynamically. Any
suggestions would be most welcome.
