[Purpose] This study investigated the reliability of the Special Support System. [Subjects and Methods] Eighteen female and 14 male volunteers participated in this study. Participants were asked to sit on the Special Support System with their chins tucked in, spines straight, pelvis neutrally positioned, and their hands placed on their thighs. They were also asked to flex their hips, knees, and ankles to approximately 90 degrees and to put their feet flat on the floor. The total contact area, mean total pressure, as well as mean and peak pressures of each quadrant were each measured 15 times. Test-retest reliability was analyzed for inflated air pressure, and pressure redistribution values by using intraclass correlation coefficients. [Results] The intraclass correlation coefficient was greater than 0.89 for inflated air pressure and greater than 0.92 for total contact area, mean total pressure, and each quadrant's mean and peak pressure. [Conclusion] The findings suggest that the Special Support System is reliable and can be used as an alternative method for redistributing sitting pressure.
[目的] 本研究调查了特殊支撑系统的可靠性。[对象与方法] 18名女性和14名男性志愿者参与了本研究。要求参与者坐在特殊支撑系统上，下巴内收，脊柱挺直，骨盆处于中立位置，双手放在大腿上。还要求他们将髋部、膝盖和脚踝弯曲至约90度，并将双脚平放在地板上。每个象限的总接触面积、平均总压力以及平均压力和峰值压力均测量15次。通过组内相关系数分析充气气压的重测信度和压力再分布值。[结果] 充气气压的组内相关系数大于0.89，总接触面积、平均总压力以及每个象限的平均压力和峰值压力的组内相关系数大于0.92。[结论] 研究结果表明，特殊支撑系统是可靠的，可作为重新分配坐姿压力的替代方法。
