Biomechanics consists of bio- meaning living and -mechanics, the classical engineering study of loading. Biomechanics is the science that studies the action of energy and forces on living bodies. The application of biomechanics ranges from the minute forces acting at the cellular level to the much larger forces humans are exposed to during everyday activities like walking, running and ladder climbing to traumatic situations like automobile crashes, playground accidents, wheelchair tipovers, slips/trips/falls and diving injuries. An injury analysis by a biomechanics expert can augment litigation preparation by bridging the gap between the doctor’s diagnosis and the mechanism of injury, as well as to determine claim validity and consistency with other evidence.
