膝關節復健機構之運動合成

Abstract

由於膝關節患者的復健需求，市場上可見多種不同型式的膝關節復健器，但其中多數都把設計的重點放在收納方便、操作簡易與其附屬功能上，較少考量人體膝關節的真實運動型式。 以人體膝關節的被動運動實驗為基礎，本研究綜合運用機構合成理論以及運動極心線之最佳化程序，嘗試尋求最接近原始動作的機構來導引膝關節。由其成果可見，合成機構的運動軌跡可與實驗所得者相符，該機構將可導引膝關節之真實動作，減少患者在使用時的不適，以發揮連續被動式運動的復建功能，從而有助於復建器的實務設計與改良。

Owing to the needs of rehabilitation, there exist many types of knee rehabilitation devices in the market. However, most of them are designed by the convenience of storage, easy operation, and other auxiliary functions. The real motion of human knees is, in general, less considered. Based on the experiment of human knee motion, this project applies the theory of synthesis and an optimization procedure towards motion centroid in order to search for the best mechanism which fits human knees. The resulted mechanism has been proved to be able to faithfully trace the paths generated by the experiment. Using this approach, it is hoped to reduce discomfort of patients in their recovery and improve the design of current rehabilitation devices.
