This study demonstrates the potential effectiveness of a dynamic resting surface which, at regular intervals, provides sitting patients complete relief of pressure for short periods of time. Resting pressure extremes ranged from 0 mm Hg to 160 mm Hg, depending on the position of the roller supports. At all positions, including the area beneath the ischial tuberosities, the pressures were well within the range of capillary pressure and usually dropped to zero pressure at regular intervals. This mechanical surface may be the beginning of a new concept in resting surfaces. In addition to providing intermittent relief of pressure to the sitting area, the surface lends itself and the patient to a mobility that has not been heretofore possible.
本研究证明了一种动态支撑面的潜在有效性，该支撑面能定期为就坐患者提供短时间的完全压力缓解。根据滚筒支撑的位置，静息压力极值范围为0毫米汞柱至160毫米汞柱。在所有位置，包括坐骨结节下方区域，压力均处于毛细血管压力范围内，并且通常会定期降至零压力。这种机械支撑面可能是支撑面新概念的开端。除了为就坐区域提供间歇性压力缓解外，该支撑面还使患者能够实现前所未有的移动性。
