 DESCRIPTION (provided by applicant): Diabetes related foot ulcers are common and their prevalence is likely to increase as the prevalence of diabetes increases. The cost of treating of diabetic foot ulcers is estimated at over $10 billion annually in the US (Gordois 2003). It has als been established that the majority of the ~60-70,000 (CDC) annual diabetes related lower extremity amputations are preceded by a foot ulcer (Pecoraro et al. 1990). Since plantar neuropathic foot ulcers are related to high plantar pressure, plantar mechanical offloading is essential to successful prevention. Rigid rocker and roller shoes have been shown to be one of the most successful footwear interventions for the reduction of plantar pressure under the metatarsal heads. However, certain aspects of current rocker shoe designs (e.g., shoe height, weight and appearance) have prevented more widespread use in diabetic neuropathic patients. In this study, we propose to develop novel patient-specific rocker and roller shoes in which the offloading is facilitated by surface geometry that is both external and internal to the shoe. The resulting shoe will not have the extreme external angle typical of previous rockers and, together with personalization based on plantar pressure distribution, it should overcome the first three of the drawbacks of traditional rocker shoes mentioned above. No prior research has specifically attempted to address modifications that may enhance hallux offloading. We propose the following specific aims: Specific Aim #1: To design and test rocker and roller shoes with a two-layer construction - where one of the layers is inside the shoe. Specific Aim #2: To incorporate rocker/roller apex placement, internal rocker placement, and insole design based on plantar pressure distribution. Specific Aim #3: To examine options for offloading the hallux.

 描述（由申请人提供）：与糖尿病相关的足部溃疡很常见，并且其患病率可能随着糖尿病患病率的增加而增加。在美国，每年治疗糖尿病足溃疡的费用估计超过 100 亿美元（Gordois 2003）。据证实，每年约 60-70,000 例 (CDC) 糖尿病相关下肢截肢手术中，大多数都是在足部溃疡之前发生的（Pecoraro 等，1990）。由于足底神经性足溃疡与高足底压力有关，因此足底机械卸载对于成功预防至关重要。刚性摇杆鞋和轮滑鞋已被证明是减少跖骨头下足底压力最成功的鞋类干预措施之一。然而，当前摇鞋设计的某些方面（例如鞋高、重量和外观）阻碍了其在糖尿病神经病患者中更广泛的使用。在这项研究中，我们建议开发新型的患者专用摇臂鞋和滚轮鞋，其中鞋外部和内部的表面几何形状有利于卸载。由此产生的鞋不会具有以前摇杆鞋典型的极端外角，并且结合基于足底压力分布的个性化，它应该克服上述传统摇杆鞋的前三个缺点。先前没有研究专门尝试解决可能增强拇趾卸载的修改。我们提出以下具体目标： 具体目标#1：设计和测试具有两层结构的摇杆鞋和轮滑鞋 - 其中一层位于鞋内。具体目标#2：结合摇杆/滚轮顶点放置、内部摇杆放置以及基于足底压力分布的鞋垫设计。具体目标#3：检查减轻拇趾负担的选项。
