• Description:
  It is well-documented that older adults have a higher risk for falling than young adults. One contributing factor to this higher risk of falling is thought to be an impaired ability to recover balance after a postural perturbation. Older adults have consistently exhibited an impaired ability to recover balance after a wide range of postural perturbations. Mackey and Robinovitch determined the largest static angle from which young and older women over 65 could recover balance upon release when using the so-called ankle strategy. Older women exhibited a 19.6% smaller maximum lean (13.1 degrees) compared to young women (16.3 degrees). Constraining balance recovery to the ankle strategy is a fairly significant constraint on body kinematics, particularly when older adults are known to exhibit greater hip motion during non-stepping balance recovery. The purpose of this study was to investigate age differences in non-stepping balance recovery capability without constraining movements to the ankle strategy. As such, participants could bend at the hips, knees, ankles, or raise portions of feet off the floor to maintain balance. [Description provided by NIOSH]
