项目摘要

The purpose of the proposed research is to measure the in vivo contact forces active across a total hip prosthesis. This will be accomplished by implanting a series of instrumented, telemeterized hip prostheses which can measure three components of force acting across the joint. The prosthesis which will be used has been developed in previous work at Case Western Reserve University. Data will be obtained at regular intervals over a minimum of one year post surgery for six patients. Data will be obtaining during a variety of activities such as walking, single and double stance, rising from sitting in a chair, as well as others. To obtain a direct comparison of measured forces versus those predicted via gait analysis and mathematical modeling techniques, a series of combined gait analysis and force data acquisition sessions will be carried out. The results will provide for the first time a direct evaluation of the accuracy of the predictive models based on optimization methods for muscle and joint forces. In addition to addressing the question of the validity and accuracy of the force prediction models, the data will be directly useful in defining loading information for design and analysis of hip joint prostheses, and patient care relative to activities of daily living.

拟议研究的目的是测量体内接触作用于全髋关节假体的力。这将通过以下方式完成植入一系列仪器化、遥测的髋关节假体，这些假体可以测量作用在关节上的力的三个分量。假肢将使用的内容是在 Case Western 之前的工作中开发的储备大学。数据将在一段时间内定期获得六名患者术后至少一年。将获取数据在步行、单站和双站等各种活动中，从椅子上站起来，以及其他人。为了获得测量的力与通过预测的力的直接比较步态分析和数学建模技术等一系列相结合将进行步态分析和力数据采集课程。这结果将首次提供准确度的直接评估基于肌肉和关节优化方法的预测模型力量。除了解决数据的有效性和准确性问题力预测模型，数据将直接用于定义用于设计和分析髋关节假体的加载信息，以及与日常生活活动相关的患者护理。
