Abstract

TMJ(TemporoMandibular Joint) is considered as the most important articulation in human body for maintaining the balance. Thus it is one of the main treatment areas in Chiropractic. Instead of Chiropractic treatment, NOSICK, a TMJ balancing device, can be used. As there is no such device to quantify the effect of NOSICK, a system was developed to measure the effect of NOSICK. This system is composed of stereo vision, infrared lights, and infrared through filter, etc. It requires optical markers for the measurement. 8 land markers were selected from the face which will show different displacement as NOSICK is applied. 11 test subjects were measured with the system developed with and without NOSICK applied. Quantifiable displacement of markers before and after applying NOSICK was successfully measured with the system developed.

카이로프래틱 치료에서 측두하악관절(TMJ)는 인체의 균형을 유지하는데 중요한 역할을 하는 관절로서 구강내 교정장치를 통해 인체의 균형을 교정할 수 있게 된다. 현재 이러한 구강내 교정장치의 효과를 스테레오비전을 이용하여 정량적으로 평가할 수 있는 측정 장치가 없었기 때문에 본 연구에서는 이를 측정 할 수 있는 시스템을 개발하였다. 이 시스템은 스테레오 비전과 적외선 조명, 적외선 통과 필터 등으로 구성되어 있으며, 광학식 마커를 피험자의 주요 부위에 부착하여야 한다. 마커의 부착위치는 얼굴의 주요 랜드 마커 중 구강내 교정장치의 착용으로 인해 변화가 나타날 수 있는 8개의 부위를 선택하였다. 개발된 시스템을 이용하여 11명의 피험자를 대상으로 교정장치 착용 전/후 마커의 변화량을 측정하였을 때, 피험자의 얼굴에 부착된 마커의 위치 변화가 정량적으로 측정되었다.
