Biomechanics is a reasonably well-developed field of study, with a modern history usually linked to the pioneering work of Prof. Y.C. Fung in the 1960s.  There are a number of dedicated biomechanics journals (including but not limited to the Journal of Biomechanics and the Journal of Biomechanical Engineering).  The field is well-enough established to have several generations of researchers working on the subject at universities across the world.  Historically there has been a strong link between biomechanics researchers and clinical medicine practitioners.  Recently there has been a sharp increase in interest in the subject (i.e. biomechanics) by applied mechanicians who did not come from a "classic" biomechanics background or training.  This is good for everyone who works in biomechanics and good for the subject in general.  However, the concern that arises in my mind is the accidental development of two independent literatures on the subject--one dominated by applied mechanics journals and one associated with the traditional biomechanics community and emphasizing Medline-indexed journals.  It is potentially concerning that there will be the potential for poor integration between the two sets of papers and thus potential for wheel-reinvention.  I don't know how to solve this problem, but it is my hope that by developing an active community online (including iMechanica) there will be good communication and collaboration between these two diverse groups, who are quite likely to attack the same problems with very different approaches.
