J Appl Physiol 109: 1786-1791, 2010. First published October 14, 2010; doi: 10.1152/japplphysiol.00390.2010.-The degree of multiscale complexity in human behavioral regulation, such as that required for postural control, appears to decrease with advanced aging or disease. To help delineate causes and functional consequences of complexity loss, we examined the effects of visual and somatosensory impairment on the complexity of postural sway during quiet standing and its relationship to postural adaptation to cognitive dual tasking. Participants of the MOBILIZE Boston Study were classified into mutually exclusive groups: controls [intact vision and foot somatosensation, n = 299, 76 +/- 5 (SD) yr old], visual impairment only (
