• Description:
  The population of adults over 55 years old in the United States increased over 15% from 2000 to 2010. Adults in this age group are more susceptible to injuries resulting from falls, including over 10,300 fatal fall-related injuries in 2000. In order to understand the mechanisms of falls and resulting injuries in the older adult population, biomechanical research is required. Biomechanical gait analysis and injury prevention research relies on anthropometric tables to give accurate approximations of body segment parameters (BSPs) of subjects. These parameters include mass, center of mass, and radius of gyration of the common body segments: upper arm, lower arm, torso, thigh, shank, and head. Current anthropometric tables were developed with college-aged adults and are proven to be inaccurate in predicting BSPs of other age groups. There are many proven ways to create predictive models such as cadaver-based studies and imaging, but each method has disadvantages such as monetary cost, time-intensiveness, and/or delivery of high doses of radiation to the participant. Dual energy X-ray absorptiometry (DXA) is a validated in-vivo method of determining BSPs. It is a quick, inexpensive, low-radiation, full-body scan that can differentiate densities of bone, muscle, and fat tissue, allowing for accurate mass calculations. This study uses DXA scanning and analyzing techniques to compare BSPs of normal-weight, young females against those of normal-weight, old females, focusing on the largest segments of the body: the torso and the thigh.
