Abstract
Leg swelling, which frequently occurs during sitting, yields languor on the lower legs and decreases sitting comfort. We focused on footrest, especially difference of footrest angle because footrest is an alternative method to decrease leg swelling and we studied of footrest angle on decrement of leg swelling by using both bioelectrical impedance method and near infrared spectroscopy. From the results we found that increase of deOXY-Hb for outflow influences a gain of leg swelling and increase of OXY-Hb for inflow influences reduction of leg swelling.
