DESCRIPTION
The primary focus of this project was to develop the technology and instrumentation for examining the age related differences in self-perception of stable and non-stable body configurations during upright postural stances. The specific hypothesis that aged subjects usually underestmate the rage of possible postural movements due to the "bracing reactions" was tested. It was also hypothezied that older adults when placed in the challenging, and thus stressful postural stances, will cope less effectively with these situations than young adults. It was inticipated that examination of spontaneous brain activity (EEG) associated with self-perception of postural movements by means of computer graphics can provide reliable information on stress coping effectiveness in the older population.
