Outline of Final Research Achievements

Throughout the three-year study, we repeated our method-based measurements and prosthesis preparation for two children with congenital arm deficit. By establishing an appropriate posture and limb position during measurement for socket molding, stable three-dimensional scanning of the amputated end of the upper limb and socket creation and use training using a 3D printer were conducted. It has become possible to accumulate measurement data over time, and to actually create and fine-tune sockets according to changes in stump size and shape due to growth. In addition, by creating a removable hand tool using CAD software, it has become possible to easily convert it into a prosthetic hand according to the purpose. We also created a new device for operating the esports controller for children with arm deficit.

Academic Significance and Societal Importance of the Research Achievements

デジタル化技術を基に経時的に変化する先天性腕欠損児の身体所見（断端のサイズや形状測定と成長に伴う変化の計測）を定量化し３Dプリンタを用いて出力する技術を確立した。この技術を通じて安価で繰り返し修正も容易な義手作成が可能となり、より早期からの義手を用いたリハビリテーション訓練介入を通じて運動学習を支援することにより、患児の将来の活動の質をより向上させるためのアプローチ実現可能性を示すことができた。
