Biomechanics-the study of the mechanical principles of living organisms-represents the foundation upon which medical innovation has been built. By using engineering methods on the living system, biomechanics extends the development of complex medical devices to enhance patient care, improve quality of life, and expand human potential further. Medical Device Understanding through Biomechanics Biomechanics is basically the analysis of forces and motions within the human body-at points from the cellular movements to the dynamics of the whole body. An interdisciplinary approach that uses biology, physics, and engineering explains the movement of the body, the response of tissues to stress, and how mechanical forces influence biological functions. Benefits that would accrue from biomechanics are important at the design of medical devices that are intended for application to or interaction with the human body and ensure efficacy and safety.
