DESCRIPTION (provided by applicant): The ability to evaluate the performance of seat cushions is critical to the development of wheelchair seating and standards, and to the selection of cushions by consumers and therapists. To assess the ability of a wheelchair cushion to distribute pressure, the Skeletal Embedded Loading Indentor (SKELI) was designed to simulate both the soft tissue and bony skeletal substructure of the human anatomy. However, the existing SKELI was molded from a single individual and does not allow the testing of cushions for nonstandard pelvis postures and sizes. This project will develop the Adjustable Skeletal Loading Indentor (ASLI), an innovative test fixture with adjustable pelvic and soft tissue components that can be configured to simulate differences in pelvic width, and pelvic tilt, rotation, and obliquity. The ability of the ASLI to mimic pelvic deformities will be verified by comparing pressure distribution patterns on four different types of commercially available cushions. Data will be analyzed in five key zones: the right and left ischial tuberosities, the right and left trochanters, and the sacrum/coccyx. The ASLI will benefit cushion users by providing needed information on cushion performance.

描述(由申请人提供)：评估座垫性能的能力对于发展轮椅座椅和标准，以及消费者和治疗师选择座垫至关重要。为了评估轮椅垫的压力分布能力，设计了骨骼嵌入式加载指示器(Skeli)来模拟人体解剖学的软组织和骨骼亚结构。然而，现有的Skeli是由单个人塑造的，不允许测试非标准骨盆姿势和大小的坐垫。该项目将开发可调节骨骼负荷固定器(ASLI)，这是一种创新的测试夹具，具有可调节的骨盆和软组织组件，可以配置成模拟骨盆宽度以及骨盆倾斜、旋转和倾斜度的差异。ASLI模拟骨盆畸形的能力将通过比较四种不同类型的商业坐垫上的压力分布模式来验证。数据将在五个关键区域进行分析：右和左坐骨结节，右和左粗隆，以及骶骨/尾骨。ASLI将通过提供有关缓冲性能的所需信息使缓冲用户受益。
