3D列印握筆器個別化設計發展，對一位大專院校脊髓性肌肉萎縮症學生書寫功能表現之研究

Individualized Development of 3D-printed Pencil Grip for a College Student with Spinal Muscular Atrophy

脊髓性肌肉萎縮症學生因為生理障礙，在就學、未來就業和就養需要科技輔具改善功能表現，於寫字能力更需個別化調整。3D列印技術可製作客製化產品，最小化其障礙限制。本研究之目的在建立3D列印技術於製作握筆器之個別化設計與發展，探討學生寫字表現。採用單一個案研究法之跨行為多基線設計，以脊髓性肌肉萎縮症學生為對象，探討建立3D列印技術個別化製作握筆器流程及抄寫表現；實驗握筆器原型共經歷六次調整，本研究以「基本讀寫字綜合測驗」探討抄寫速度表現、以光學字元辨識軟體判讀抄寫品質。經過施測、介入後，顯示3D列印技術應用於個別化握筆器之設計與發展具可行性；脊髓性肌肉萎縮症學生使用3D列印握筆器後，抄寫速度有提升、抄寫品質有改善。3D列印技術可應用於特殊教育領域中為更多有特殊需求的學生解決問題。

Students with Spinal Muscular Atrophy (SMA) usually need technical aids to improve their functional performance, especially in writing, at school, in the workplace, and at home. Since the students' writing performance varies, the aids require individualized adjustments. Taking advantage of the capability of customizing products through 3D printing technology, the author aimed to design a 3D-printed assistive device to minimize the writing obstacles faced by SMA students-pencil grip. The study was to establish the individualized development of a 3D-printed pencil grip, and to explore its effectiveness through single-subject multiple-baseline-across-behaviors research design. The research used The Battery of the Chinese of Pupils and CamScanner, an optical character recognition software, to examine the writing speed and quality of SMA college students. There were two SMA college students in the practice test development stage and in the official test stage who had their writing performance examined both with and without the pencil grip. Results showed that designing individualized 3D printed pencil grips was feasible. Additionally, 3D-printed pencil grips could be used by students with SMA to improve their writing speed and quality. Suggestions on research methods and related aspects were provided as they related to 3D printing technology in special education so as to help even more students with special needs.
