类风湿性关节炎（RA）患者最常见的症状之一是膝关节出现问题。然而，用于诊断这种损伤的方法是昂贵的和/或侵入性的。这项工作描述了一个系统的设计和应用，该系统能够使用加速度计非侵入性地评估膝关节的变化。三个垂直安装的加速度计向便携式仪器提供信号。研究膝关节振动功率在2至10 Hz之间的体内试验显示RA患者的数值增加（p<0.006）。该系统可作为评估风湿性关节炎引起的膝关节变化的有用工具。
One of the most common occurrences in patients with rheumatoid arthritis (RA) is the presence of problems in the knee joint. The methods used in the diagnosis of this damage, however, are expensive and/or invasive. This work describes the design and application of a system able to non-invasively evaluate changes in knee joint using accelerometry. Three accelerometers mounted perpendicularly were used, providing signals to a portable instrument. In vivo tests investigating the knee joint vibration power between 2 and 10 Hz showed increased values in RA patients (p<0.006). The developed system could be a useful tool for the evaluation of changes in the knee joint introduced by RA.
