Little research has tested instructional feedback effects on functional tasks. Effect of summary knowledge of results (KR) feedback (FB) on standing balance was investigated in healthy women, using a force platform. Ten young and ten older women were pretested on gait, standing balance symmetry, limits of stability in standing, and step stance center of pressure (COP) movement control. Half received summary KR FB on their pretest step stance COP movement control performance. The others received no FB. All subjects practiced step stance COP movement control with no FB, then were posttested. There were no significant age-related differences at pretesting, and no differences between pretest and posttest performances on any measure, regardless of FB status. Limits of stability in standing and step stance COP movement control were stable measures over time. Step stance COP movement control may only be sensitive to impairment related changes, not age-related changes.
