I really enjoy studying biomechanics. I find it totally fascinating to learn, for example, that a certain muscle is very well suited to stabilize a joint, but not to move it through a large range of motion; or that it is active in one movement but not another; or that it becomes atrophied in people with chronic pain. I think this kind of detective work is very cool and I always look forward to applying it to help one of my clients. But that is where things get frustrating, because with biomechanics, as with so many other subjects, the more you learn, the more you realize you don't know as much as you would like to know. And sometimes you don't know enough for your treatment protocols to make any sense.
