Abstract: Experimental and simulation-based assessment of the human postural response to sagittal plane perturbations with localized muscle fatigue and aging Bradley Steven Davidson (ABSTRACT) This research was motivated by occupational falls, which are one of the leading causes of fatalities in skilled labor divisions. The effects of localized muscle fatigue (LMF) on surrogate measures of postural sway are well-established. This is significant since these increases have been linked to elevated risk of falls, and workers with increased risks of falling fatality frequently engage in fatiguing tasks. An initial study was conducted to investigate the effects of LMF and aging on balance recovery from postural perturbations without stepping. Sagittal plane perturbations were administered to young and older individuals before and after fatiguing exercises. Measures of balance recovery (BR) were based on the center of mass (COM) and center of pressure (COP) trajectories and the maximum perturbation that could be withstood. Changes in
