Project Summary/Abstract The proposed project relates to developing and evaluating an innovative, inexpensive, easy-to-use chair aiming to reduce the prevalence of pressure injuries among persons living with Alzheimer's disease or a related dementia (ADRD). The Agency for Healthcare Research & Quality estimates that more than 2.5 million individuals in the United States develop pressure injuries annually, resulting in treatment costs exceeding $10 billion per year. The condition is painful, often difficult to treat, and over 60,000 people die due to pressure injuries each year in the United States alone. Persons living with ADRD, both in long term care facilities and private residences, are at an increased risk for pressure injury formation due to the deterioration of several neurophysiological subsystems associated with motor, sensory, autonomic, cognitive, or behavioral pathways. Physical repositioning is the cornerstone of pressure injury prevention (and mandated by government regulation in beds); however, several barriers exist to conducting frequent, scheduled repositioning of persons living with ADRD in chairs. Some interventional technologies that have been developed for bed mattresses including reactive foam, static air, water, fiber, gel surfaces, and air‐fluidized ceramic beads along with active approaches including alternating pressure air surfaces, large‐celled ripple mattresses. Active alternating pressure air surfaces are made of air‐cells that intermittently inflate and deflate via electrically powered air compressors to regularly redistribute the pressure under the body. These mattress developments are slowly being applied to chairs. Despite the advantages of alternating pressure air surfaces, this type of surface in a chair overlay is not in ordinary widespread use due to cost, patient discomfort associated with inflation/deflation motion, compressor noise, and energy consumption. We propose an innovative low-cost chair design approach that achieves the functionality of an alternative pressure surface mattress without the need for electricity or compressed air. We hypothesize that the proposed chair will be suitable for widespread adoption both in long-term care facilities and private residences. It will be particularly useful in low-resource care environments. A prototype chair will be developed and evaluated.

项目概要/摘要 拟议的项目涉及开发和评估一种创新、廉价、易于使用的椅子，旨在 减少阿尔茨海默病或相关疾病患者压力性损伤的发生率 医疗保健研究与质量局估计超过 250 万人患有痴呆症。 美国每年都有人发生压力性损伤，导致治疗费用超过 10 美元 每年有超过 6 万人因压力而死亡。 仅在美国，每年就有 ADRD 患者受伤，无论是在长期护理机构还是在医院。 私人住宅，由于一些设施的恶化，形成压力损伤的风险增加 与运动、感觉、自主、认知或行为途径相关的神经生理子系统。 身体重新定位是预防压力性损伤的基石（由政府强制执行） 然而，对人员进行频繁、有计划的重新定位存在一些障碍。 一些针对床垫开发的介入技术。 包括活性泡沫、静态空气、水、纤维、凝胶表面和空气流化陶瓷珠以及活性材料 方法包括交替压力空气表面、大孔波纹床垫。 压力空气表面由气囊组成，通过电动空气间歇性地充气和放气 压缩机定期重新分配身体下方的压力。这些床垫的发展进展缓慢。 尽管交替压力空气表面具有优点，但这种类型的表面在 由于成本、患者不适等原因，椅子覆盖层并未得到广泛使用。 我们提出了一种创新的低成本方案。 椅子设计方法实现了替代压力表面床垫的功能，而无需 我们发现所提议的椅子将适合广泛使用。 长期护理机构和私人住宅的收养对于资源匮乏的地区尤其有用。 将开发和评估护理环境原型。
