| Summary: | 碩士 === 中原大學 === 工業工程研究所 === 86 === Carpal tunnel syndrome ( CTS ) is a common chronic disease in industry. Quantitative measurements of wrist motion are critical to understanding the relationship between CTS and wrist motion. To develop an electrogoniometer which is lightweight, easy to wear, and accurate, and which can real-time display wrist flexion/extension and ulnar/radial angle is the purpose of the study. The study also validates the custom-built electrogoniometer. There are three subsets in static validation experiments. The result shows that the average angle error is 3.44 degree and standard deviation is 3.36 degree. The average angle error of the first subset of static validation experiments is 4.58 degree and standard deviation is 3.12 degree. The average angle error of the second subset of static validation experiments is 1.38 degree and standard deviation is 0.95 degree. The average flexion/extension angle error of the third subset of static validation experims is 5.87 degree and standard deviation is 3.83 degree. The average ulnar/radial angle error ofthe third subset of static validation experiments is 1.65 degree and standard deviation is 1.80 degree. There are two subsets in dynamic validation experiments. In the first dynamic validation experiment, minimum angle position and maximum angle acceleration show significant differences between different equipment and maximum angle position shows a significant difference between different motion paces. In thesecond dynamic validation experiment, maximum angle velocity, maximum angle acceleration, and minimum angle acceleration show significant differences between different equipment. Minimum angle accelerat shows a significant difference between different motion paces. The result of the application experiment shows that there is no significant difference between the result of Ojima et al.[1991, 1992] and this study. The result of this study is somewhere between the result of Ojima et al. and Salvia et al.[1994].
