• Description:
  Body segment parameters (BSPs), including segment mass, length, center of mass location, and moment of inertia are used in many ergonomic applications, such as design of tools, protective clothing, equipment and work space layout, as well as in biomechanical models used to estimate risk of musculoskeletal injuries. Current anthropometry tables, which show the mass of each body part as a percent of total body weight (BW), and center of mass (COM) and radius of gyration (RG) locations as percent of segment length were compiled using healthy, college-age adults, however these parameters have shown to be inaccurate in predicting BSPs in subjects with an increased body mass index (BMI), as well as in different age groups. Several methods exist for determining BSPs including cadaver-based studies, magnetic resonance imaging, computed tomography, and measurements based on bony landmarks, however these methods have some issues as far as cost, time required, and high doses of radiation. Dual energy x-ray absorptiometry (DXA) is a validated method of determining BSPs in vivo that avoids these common problems. DXA scans are commonly used to determine bone density and body composition, as well as for mass calculations. The scan itself is an inexpensive, low radiation scan that differentiates between bone, muscle, and fat, and assigns mass values to each pixel based on assumed density for each classification. The goal of this study is to use DXA scan-based BSP calculations in order to determine the impact of age and BMI on segment masses, COM's, and RG's in working females, focusing specifically on torso parameters.
