Abstract

Objectives: The purpose of this study of the Thoracic Spinal Exercise Program was to evaluate its effects on VDT workers. These effects were found to include a decrease thoracic kyphosis, increase thoracic spine mobility and decrease in the VAS (visual analog scale). These measures provide a means of assessing the muscle endurance and muscle strength of the subjects. Methods: This study was conducted during the period from July 1 to August 31, 2003, and involved 58 VDT workers belonging to a company located in Seoul who were working seated in front of a computer for most of the day. After applying the thoracic exercise program, we examined the changes in the of thoracic kyphosis angle, spinal length (C7-S3), TFED (thoracic flexibility in the extension direction), MEBH (maximal elevation with both hands in the overhead direction) and CE (chest expansion). Results: Obtained from this study are as follows. 1. A significant reduction in the VAS was observed in the exercise group (pre-exercise 5.90$\pm$0.88 points, post-exercise 4.23$\pm$0.82 points), as compared with the control group (pre-exercise 6.00$\pm$0.90 points, post-exercise 5.93$\pm$0.81 points). 2. A significant reduction in thoracic kyphosis (pre-exercise 36.97$\pm$7.49, post-exercise 31.83$\pm$5.90) and a significant increase in thoracic flexibility in the extension direction (pre-exercise 7.47$\pm$2.30, post-exercise 11.77$\pm$3.65) were observed in the exercise group. The thoracic kyphosis angle showed a significant reduction in the exercise group, as compared to the control group. The thoracic flexibility in the extension direction showed a significant increase in the exercise group, as compared to the control group. 3. There was a significant increase in the spinal length in the exercise group (pre-exercise 494$\pm$27.66 mm, post-exercise 518.60$\pm$27.95 mm). Conclusions: The Thoracic Spinal Exercise Program results in an increase in thoracic spine mobility and a decrease in pain. In practical terms, the effects of the exercise program are good health and posture.

목적: 본 연구는 VDT 작업자에 대한 흉추운동프로그램의 효과에 관한 연구로서 운동을 통하여 흉추 유연성 및 통증감소를 확인하기 위하여 시도 되었다. 방법: 서울 H업체에서 컴퓨터 업무에 종사하는 사무직 근로자 58명을 무작위로 선출하여 운동군 30명 과 대조군 28명 대상으로 2003년 7월 1일부터 8월30일에 걸쳐 총 8주 동안 흉추신장운동을 주 3회 실시 하였다. 결과: 1. 흉추운동프로그램을 적용 후 흉추후만감소와 흉추신전의 유연성 증가를 보였다. 흉추후만각의 총합은 운동 전 36.97$\pm$7.49점에서 운동 후 31.83$\pm$5.90도로 흉추후만의 각도가 감소하였다. 흉추신전의 유연성은 운동 전 7.47$\pm$2.30도에서 운동 후 11.77$\pm$3.65로 증가를 보였다. 2. 흉추운동프로그램을 적용 후 흉곽확장과 양손머리위 올리기의 증가를 보였다. 흉곽확장은 운동전 80.43$\pm$7.00 cm에서 운동 후 82.48$\pm$7.65 cm로 증가를 보였다. 양손 머리위 올리기는 운동 전 200.88$\pm$5.30 cm에서 운동 후 203.56${\pm}$5 .54로 증가하였다. 3. 흉추운동프로그램을 적용 후 척추길이(C7${\sim}$S3)는 운동 전 494.0$\pm$27.66 mm에서 운동 후 518.60$\pm$27.95 mm로 유의한 증가를 보였다. 또한 통증 시각 상사척도(VAS)는 운동 전 5.90$\pm$0.88점에서 운동 후 4.23$\pm$0.82점으로 감소하였다. 4. 흉추운동프로그램을 적용하지 않은 대조군은 통증 시각 상사척도를 제외한 흉추신전의 유연성, 흉곽확장, 양손 머리위 올리기, 척추길이(C7${\sim}$S3)는 감소되었으며 흉추후만각의 총합은 증가되었다. 통증 시각 상사척도는 처음 측정 시는 6.00$\pm$0.90로, 재측정 시는 5.93$\pm$0.81로 나타나 처음 측정과 재측정 간에는 큰 차이가 없는 것으로 조사되었다. 결론: 이상의 결과로 보아 운동의 전후 차이는 흉추운동의 효과를 입증할 수 있었고 VDT 작업자에게 지속적인 흉추운동의 개입을 통하여 운동프로그램의 유의성을 알 수 있었다.
