Abstract

In this study, local blood flow (LBF) was measured by using a near infrared light oxygenation (NIRO) monitor. Subjects were sitting on office chairs and a Sitzball (balloon shaped chair). LBF in Sitzball sitting condition was significantly greater than that in control condition. Physiological effects of Sitzball were discussed.
