• Description:
  Nearly 26% the United States population is over the age of 55, a number that is consistently rising. Unfortunately, adults over 55 years old are more at risk of falling, which can be detrimental to both a person's health and finances. In 2000, the average cost of a hospital visit as a result of a fall injury was $35,000. Biomechanical research and gait analysis greatly assist in understanding the mechanism of falls. With adequate research and understanding, measures can be taken to reduce risk and prevent falls in older adults. However, the analysis of such biomechanical research is done using anthropometric tables which provide approximations for body segment parameters (BSPs), including mass, center of mass, and radius of gyration of the head, torso, upper arm, lower arm, thigh, and shank. These tables are often derived from young, healthy subjects and are not accurate in applications elderly persons. One of the current standard anthropometric methods, the Zatsiorsky regression models, was derived using gamma scanning on mostly young males. Dual energy x-ray absorptiometry (DXA) is a safe method to obtain in-vivo subject-specific BSPs. This technology is able to determine the differences between bone, muscle, and fat [5], and calculate masses based on assumed densities for each tissue type. The goal of this study was 2 -fold: (1) investigate age-effects in the thigh BSPs between young and older female adults, and (2) evaluate the accuracy of the Zatsiorsky method compared to the in-vivo DXA measures in the same sample of participants. For brevity purposes, we conducted our analyses on the thigh due to the significant large inertial effects of this segment. [Description provided by NIOSH]
