Biomechanics is the application of mechanics and physics to biological systems. It is generally used to mean things like human movement and using mechanical principles to understand how humans move and what affects that movement. Even though that is the popular understanding of what biomechanics is, it is also applicable to any biological system from animals to plants and from organs to cells and how they move and how the forces of physics affect them. Those who work in biomechanics come from diverse backgrounds. Some of them work in labs designing products; some work in clinics and do interventions to change or improve a patient’s biomechanics; and some of them work in universities where they do pure research to understand how humans, animal and even how our DNA move.
The clinical application of biomechanics is variable. In Podiatry, for example, it is all about a system of movement and its application to clinical foot problems that was originally developed by Merton Root. He had a system whereby there was a defined criteria for normal and if there was a deviation from that normal, then the foot would function differently and cause a range of clinical problems. This is the application of biomechanics to how the foot function and the design of foot orthotics to change the way that the foot functions biomechanically. In running, biomechanics is concerned with the running technique and how the runner moves and looks for ways to improve it so runners can run faster. Biomechanics is also used to help with the design of and the improvement of running shoes. Most of the running shoe companies biomechanics labs for product design and product testing. If you think that you have a problem that is related to your own biomechanics of the foot ro lower leg, then see a podiatrist with experience in these sorts of problems.
