Video based analysis of standing balance in a community center.
Postural sway is a well known measure of postural stability in the elderly. Sway measurements, however, are typically made using expensive equipment in a laboratory. We report on efforts to make clinically significant and quantitative measurements of postural sway in a community center with a single un-calibrated video camera. Results indicate that simple tracking technologies can capture some aspects of sway in a community center in a way that is perceptually accurate and capable of distinguishing expert-assigned levels of balance performance in an elderly, balance impaired cohort.
