Abstract

The purpose of this study was to investigate the effect of a new designed splint on the hand function. A new design splint that enlarges the area between thumb and index finger was manufactured using 3D printing. After wearing a new splint the patient was possible to open thumb and hold a small object. She showed improvement in overall hand function and could move eight blocks in box and block test. But grasping a cup without a handle has become more difficult than before. Also there is a disadvantage that it could not be fixed by water. This study is meaningful in that it is the first splint application study using 3D printing. In the future, we expect that various patient-specific splints will be developed through 3D printing in the field of occupational therapy.

본 연구의 목적은 손을 기능적 자세로 만들어주는 새로운 디자인의 보조기를 환자에게 적용하여 손기능에 어떠한 영향을 주는지 알아보고자 하는 것이었다. 새로운 보조기는 엄지와 검지의 샅공간(web space)을 넓히는 새로운 디자인이다. 보조기 착용 후 환자는 엄지 벌림의 자세를 유지할 수 있었고 작은 물건 잡기가 가능하게 되었다. 환자는 손 기능에서 향상을 보였고 Box and Block 검사의 수행이 가능해져 1분에 8개의 블록을 옮길 수 있게 되었다. 그러나 물건에 손바닥의 접촉이 요구는 잡기는 이전보다 더 어려웠고 일상에서 착용시 물이 닿으면 고정되지 못한다는 단점 또한 있었다. 본 연구는 3D 프린팅을 이용한 첫 보조기 적용 연구라는 점에서 의미가 있으며 앞으로 작업치료분야에서 3D 프린팅을 통해 다양한 환자 맞춤형 보조기가 개발될 수 있을 것이라 기대한다.
