Abstract

This study examined the effects of the location and direction of the scolioti curve on postural balance in patients with idiopathic scoliosis. Fifteen subjects were divided into three groups: right thoracic curve group, left lumbar curve group, and double curve group. The dynamic trunk motion (angle variation in the lumbar, thoracolumbar, lower thoracic and upper thoracic region) and plantar pressure distribution (maximum force and peak pressure) were assessed using an ultrasound-based motion analysis system and Emed-at platform system. From the results, it was confirmed that patients with idiopathic scoliosis showed postural imbalance with an increased angle and pressure asymmetry according to the location and direction of the scoliotic curve for dynamic trunk motion and plantar pressure distribution. In addition, there were differences in the postural balance pattern between the single curve and double curve groups. Further studies for developing a rehabilitation training device will be conducted to improve the postural control ability and trunk balance as well as treat scoliosis based on the results of this study.

본 연구에서는 척추측만증 환자의 척추 만곡 위치와 방향이 자세 균형에 미치는 영향을 평가하였다. 총 15명의 실험대상자를 흉추 만곡 그룹, 요추 만곡 그룹, 이중 만곡 그룹으로 분류하여 연구를 진행하였다. 초음파 기반 동작 분석 시스템과 압력 분포 시스템을 사용하여 환자의 동적 체간 움직임(요추, 흉요추, 하흉추, 상흉추에서의 각도 변화)과 족저 압력 분포(최대힘, 최대압력)을 측정하였다. 측정 결과를 통해, 특발성 척추측만증 환자의 동적 체간 움직임과 족저 압력 분포 모두 척추 만곡의 발생 부위와 방향에 따라 비대칭적으로 각도와 압력이 증가하면서 자세 불균형이 발생하는 것을 알 수 있었다. 또한, 단일 만곡과 이중 만곡을 가진 그룹 간의 자세 균형 패턴에서의 차이를 확인할 수 있었다. 추후 연구에서는 본 연구에서의 결과를 기반으로 척추측만증 환자의 자세 조절 능력과 체간 균형을 향상시키고 척추측만을 치료하는데 도움을 줄 수 있는 재활 훈련 장치를 개발하고자 한다.
