The purpose of this study was to determine the usefulness of custom-contoured cushions (CCCs) in providing a safe sitting surface. The efficacy of CCCs was investigated using ten spinal cord injured persons who evaluated contoured foam as their primary wheelchair cushion. External pressures at the seat interface were measured on a subject's regular cushion and on a CCC to compare the respective load distributions. Pressure distributions measured on a CCC were statistically lower than those measured on the subject's usual cushion (p less than .05). Eight clinical variables were used to judge each cushion's effect on the functional abilities of wheelchair users. Sitting on a CCC seemed to improve posture and balance when compared to the subject's regular cushion. Based on these results, it is suggested that contouring technology be developed as a clinical tool for managing wheelchair users' seating problems.
本研究的目的是确定定制轮廓坐垫（CCC）在提供安全坐姿表面方面的实用性。使用10名脊髓损伤患者对CCC的功效进行了研究，这些患者将轮廓泡沫作为他们的主要轮椅坐垫。在受试者的常规坐垫和CCC上测量座椅界面处的外部压力，以比较各自的负荷分布。在CCC上测量的压力分布在统计学上低于在受试者常用坐垫上测量的压力分布（p小于0.05）。使用八个临床变量来判断每个坐垫对轮椅使用者功能能力的影响。与受试者的常规坐垫相比，坐在CCC上似乎能改善姿势和平衡。基于这些结果，建议将轮廓技术开发为一种管理轮椅使用者坐姿问题的临床工具。
