컴퓨터영상단말기증후군을 위한 운동프로그램이 사무직 근로자의 척추정렬과 경부통증에 미치는 효과 = The Effects of Training Program for Video Display Terminal Syndrome on Spine Curvature and Cervical Pain in Office Workers

국문 초록 (Abstract)

이 연구의 목적은 사무직근로자의 컴퓨터영상단말기증후군(Visual Display Terminal Syndrome, VDTS)의 개선을 위한 인간공학 및 운동 처치의 개입이 경부장애지수(Neck Disability Index, NDI) 및 척추만곡도(Spinal Curvature, SC)와 관련된 근골격계질환에 미치는 영향을 조사하는 것이다. 이러한 연구 목적을 달성하기 위하여 통제군(n=8)에게 모니터, 책상, 의자 및 키보드의 위치 그리고 모니터 화면의 밝기 등과 같은 인간공학적 작업환경의 변화가 적용되었다. 이와 달리, 실험군(n=13)은 컴퓨터 작업환경의 개선과 더불어 척추 주변 근육을 위한 스트레칭 및 안정화 운동프로그램이 8주간(주3회) 적용되었다. 그 결과, 흉추 48도 및 요추 40도의 기준각도에 근거하여 사전 사후의 변화를 집단별로 비교한 결과, 실험군에서 흉추 및 요추만곡도에 긍정적인 변화가 발견되었다(p<.01). 또한 NDI는 사전 사후의 차이 비교를 실시한 결과, 실험군이 비교군보다 유의한 경부 통증의 개선 효과를 보여주었다(p<.01). 그러므로, 좌업식 작업에 노출되어 있는 사무직 근로자들의 근골격계질환을 개선시키기 위하여 작업환경과 같은 인간공학적 중재와 더불어 능동적이고 적극적인 중축골격 및 척추 주변 근육 강화를 위한 운동프로그램이 함께 적용되어야 한다.

다국어 초록 (Multilingual Abstract)

The purpose of this study was to investigate the effects of working environment and intervention exercise programs for office workers with Visual Display Terminal Syndrome (VDTS) on musculoskeletal disease related to Neck Disability Index (NDI) and Spinal Curvature (SC). For the control group (n = 8) modifications in the working environment such as the height and position of the monitor, the desk and the chair, the angle of the keyboard and the brightness of the monitor screen were applied, and the experimental group (n = 13) experienced the working ergonomic modification as well as a stretching and stabilization exercise program to strengthen core muscles for 8 weeks (3 times a week). As a result, based on the reference angles of 48 degrees for thoracic spine and 40 degrees for lumbar spine, experimental group showed positive changes in thoracic and lumbar spine curvature (p <.01). In addition, the NDI showed a significant improvement in the experimental group compared to the control group as a result of comparing the pre to post difference (p <.01). Improving the symptoms of VDTS with ergonomic intervention is not sufficient, and it is thought that an additional intervention of mid- and long-term exercise program may be necessary for significant improvement of musculoskeletal diseases. It is recommended that office workers with computer work environment may need to apply ergonomic intervention as well as axial skeleton and core muscle oriented exercise program for long period of time to reduce VDTS-based symptoms.
