9725134 Bruckner The object of the proposed research is to gather additional preliminary data to support the development of computer models and new technological tools for the evaluation, treatment and prevention of gait disorders arising from foot problems associated with subtalar joint (STJ), located between the talus and the calcaneus in the foot, plays a significant role in both the efficiency of modern human bipedal locomotion and the pathogenesis of injuries in the foot, knee, pelvic girdle and low back. The PI's investigations show that some STJ configurations mechanically restrict joint range of motion (ROM) while other STJ facet configurations do not. Persons with the more restricted or "rigid" STJ configurations have a statistically significant higher incidence of heel spurs than people with mobile STJ configurations. Others have found that osteoarthritis is more prevalent in joints with mobile STJ configurations and conclude that the osteophytes probably form to stabilize a structurally hypermobile system. This SGER proposal is designed to gather evidence supporting the hypothesis that people with rigid STJ configurations have a measurable difference in their gait patterns when compared to people with mobile STJ configurations. This study represents a small-scale, exploratory investigation in support of a long term goal of uniting bioengineering with physical therapy to address some of the biomechanical problems seen in the foot, lower limb and spine. The results will be new technological tools that will enable clinicians to identify foot deformities with a high degree of validity and reliability, study the gait of people with foot deformities and fabricate shoes and foot orthoses dynamically to correct and, eventually, prevent gait problems. ***

9725134 Bruckner拟议研究的目的是收集额外的初步数据，以支持计算机模型和新技术工具的开发，用于评估、治疗和预防与距下关节（STJ）相关的足部问题引起的步态障碍，距下关节位于足部的距骨和跟骨之间，在现代人类双足运动的效率和足、膝、骨盆带和下背部损伤的发病机制中起着重要作用。 PI的调查表明，一些STJ配置机械限制关节活动范围（ROM），而其他STJ关节面配置则不会。 与具有移动的STJ构型的人相比，具有更受限或“刚性”STJ构型的人具有统计学显著更高的足跟骨刺发生率。 其他人发现骨关节炎在具有移动的STJ构型的关节中更普遍，并得出结论，骨赘的形成可能是为了稳定结构上过度移动的系统。 该SGER提案旨在收集支持以下假设的证据：与具有移动的STJ配置的人相比，具有刚性STJ配置的人的步态模式存在可测量的差异。 这项研究是一项小规模的探索性研究，旨在支持将生物工程与物理治疗相结合的长期目标，以解决足部，下肢和脊柱中出现的一些生物力学问题。 研究结果将成为新的技术工具，使临床医生能够以高度的有效性和可靠性识别足部畸形，研究足部畸形患者的步态，动态地制造鞋子和足部矫形器，以纠正并最终预防步态问题。 ***
