Abstract

Objective: To examine the relative efficacy of three active exercise programs for work-related, chronic low back pain, and to observe to what extent the programs affected the mechanical stability of the lumbar region. Methods: The subjects were 64 employees who were randomly divided into three groups to match the three active exercise programs which were performed 3 times a week for 6 months. All subjects were assessed with the same measurements at a pre-study examination, and then were reassessed at 2 weeks, 3 months and 6 months after the study. Results: The pain intensity didn’t show any significant difference among the three groups. However, the Oswestry Disability Index showed significant differences among the three groups at 6 months and the lumbar and thoracic exercise groups showed significant decreases compared to the general physiotherapy group (p<0.05). Maximal stretching with both hands in the overhead direction showed a significant difference among the three groups at 3 months and 6 months, and the thoracic exercise group at 6 months showed a significant increase in overhead stretching compared to the lumbar exercise and general physiotherapy groups (p<0.05). The lumbar region angle of inclination showed significant differences among the three groups at 2 weeks, 3 months and 6 months, with the thoracic exercise group being decreased significantly more than the lumbar exercise and general physiotherapy groups at 6 months (p<0.05). Conclusions: Exercise aimed at increasing thoracic mobility has an effect on lumbar stability. Furthermore, it is far more effective for lumbar stabilization than general physiotherapy and deep muscle strengthening lumbar exercise.

목적: 본 연구는 만성 요통근로자의 세 가지 능동적 운동프로그램 효과에 관한 연구로서 능동적 운동이 요추의 안정성 향상에 미치는 영향을 알아보고자 시도되었다. 방법: 3개월 이상 만성요통을 호소하는 64명의 근로자 대상으로 무작위로 일반적인 물리치료그룹, 요추 운동그룹, 흉추 운동그룹, 세 그룹으로 나누었다. 능동적 운동프로그램은 주 3회, 6개월 동안 실시하였으며, 통증강도, Oswestry 장애지수, 양손을 머리위로 최대한 올려 높이측정, 요추부 경사각도를 평가하였다. 모든 대상자들은 연구 전, 연구 후 2주, 3개월, 6개월을 같은 측정방법으로 재평가하였다. 결과: 통증강도는 세 그룹 간에 통계적으로 유의한 차이가 없었다. Oswestry 장애지수는 연구 후 6개월에서 세 그룹 간에 유의한 차이가 있었으며, 요추운동그룹과 흉추운동그룹이 일반적인 물리치료그룹에 비하여 유의하게 감소하였다(p<0.05). 양손을 머리위로 최대한 올려 높이측정은 연구 후 3개월과 6개월에서 세 그룹 간에 유의한 차이가 있었으며, 연구 후 6개월에서는 흉추운동그룹이 일반적인 물리치료그룹과 요추운동그룹에 비하여 유의하게 증가하였다(p<0.05). 요추부 경사각도는 연구 후 2주와 3개월, 6개월에서 세 그룹 간에 유의한 차이가 있었으며, 연구 후 6개월에서는 흉추운동그룹이 일반적인 물리치료그룹과 요추운동그룹에 비하여 유의하게 감소하였다(p<0.05). 결론: 3개월 이상 만성 요통을 호소하는 근로자 대상으로 흉추의 운동성 증가를 위한 운동프로그램을 적용하여 흉추의 운동성을 증가시킨 결과에서 보면, 2주 시행하였을 때 요추의 신전 운동프로그램 보다 요추의 안정성 향상에 효과적이며, 6개월 시행하였을 때만, 요추의 심부근근력강화 운동프로그램보다 요추의 안정성 향상에 효과적이었다. Oswestry 장애지수는 요추의 심부근 근력강화 운동프로그램과 동일하게 감소하였고, 통증강도는 세 그룹 모두 2주 시행하였을 때 감소하는 것으로 나타났다.
