Summary	Body balance in the elderly is measured by the length of time they can remain standing on a single leg, when evaluating their body balance. However this is not enough to see how they move their body to control their balance. It is difficult to evaluate the body balance during orthopedic examinations because of limited space and time. We developed a simple evaluation method to quantify the body balance by measuring the motion of the trunk from images appearing on a single video camera setup in front of people standing on a single leg. We examined the movement of the trunk in 9 subjects aged 39 - 70 years old, when they shifted from the standing position on both legs to the standing position on a single leg. We measured the angles of the shoulders and the pelvis, and the pelvis angle decreased after 8 weeks of exercise. We obtained the same results when we compared this with the three dimensional motion analysis and single video analysis. This is a simple and effective way in evaluating body balance using a single video camera.
