DESCRIPTION (provided by applicant): It is the ultimate objective of this research team to develop a mathematical model of the foot structure that is sensitive to aberrant function and can be used to plan more effective conservative and surgical treatments. The mission of the NICHD is to ensure the health, productivity, independence, and well-being of all people through optimal rehabilitation. The proposed forefoot model would be useful as a guide to Podiatric physicians, Orthopedic surgeons, Physiatrists, and Physical Therapists to optimize treatment strategies in order to better rehabilitate patients. This project will focus upon three specific aims: (A) to develop a structural model of the forefoot from radiographic and 3D digital pointer based input data and demonstrate concurrent validity, (B) to develop a normative database of model parameters and associated foot function during gait for asymptomatic healthy individuals and stratify across foot type (i.e. pes planus, rectus, and pes cavus), and (C) to distinguish the model parameters and foot function for a group of patients with diabetes and hallux abducto valgus (HAV) from that of healthy. Improved understanding of the pathomechanics that afflict pes planus (e.g. HAV, Hallux limitus, osteoarthritis, tendonitis, plantar fasciitis, neuroma, posterior tibial dysfunction, chronic keratomata, collapsing pes valgus.etc) and pes cavus (e.g. hammertoes, tailor bunion, metatarsalgia, diabetic neuropathy, etc.) feet is needed. The proposed model of forefoot geometry is expected to be sensitive to different foot structures (and associated pathologies) and hence be predictive of commensurate foot function. Based upon positive findings from this investigation subsequent studies will be conducted to use the model as a tool for clinical decision making. Individuals with diabetes and lack of sensation may develop limb threatening wounds beneath their feet. If an ulcer forms and does not heel quickly an infection may ensue. If not successfully treated this infection could result in gangrene and the necessity for amputation. One goal of the proposed model is to predict the abnormally high pressures beneath these patients' feet so as to alert clinicians and suggest a course of action.

描述（由申请人提供）：这是该研究团队的最终目标，是开发对异常功能敏感的脚结构的数学模型，并可以用于计划更有效的保守和手术治疗。 NICHD的使命是通过最佳康复来确保所有人的健康，生产力，独立性和福祉。拟议的前脚模型将作为足病医师，骨科医生，生理学家和物理治疗师的指南，以优化治疗策略，以便更好地修复患者。该项目将侧重于三个具体目的：（a）从放射线图和基于数字指针的基于数字指针的输入数据中开发前脚的结构模型，并证明并发有效性，（b）以开发模型参数的规范数据库，并在步态过程中进行步态的相关脚部功能，以使其无症状的个体跨脚类型分层（即，pes planus topers topers topers of。对于一组糖尿病患者和健康的糖尿病患者（HAV）。对遭受PES Planus（例如Hav，Halux limus，骨关节炎，肌腱炎，足底筋膜炎，神经瘤，胫骨后功能障碍，慢性角膜症，慢性角膜肿瘤，慢性角膜炎，pes venc.etc）和Pes cavus cavus cavus（例如cavus cavus cavus cavus，cavus cavus，cavus，cavus，需要神经病等。预计所提出的前脚几何形状模型对不同的脚结构（以及相关的病理）敏感，因此可以预测相应的脚部功能。根据该调查的积极发现，随后的研究将使用该模型作为临床决策的工具。糖尿病和缺乏感觉的人可能会在脚下造成肢体威胁伤口。如果形成溃疡并且不迅速脚跟，可能会发生感染。如果未成功治疗这种感染可能会导致坏疽和截肢的必要性。该模型的一个目标是预测这些患者脚下的异常压力，以提醒临床医生并建议采取行动。
