Background: Flat-back posture refers to a posture in which the pelvis is tilted backward, the lumbar spine is bent, the upper thoracic spine is increasingly bent, and the lower thoracic spine is straight. Given that most of the day is spent sitting, we need to develop exercise programs and devices that are suitable for people who spend less time exercising than sitting. Objects: This study investigated the effects of resistance footrest exercise on spine posture angles in visual display terminal (VDT) workers with flat back. Methods: We measured the upper lumbar angle (ULA) and lower lumbar angle (LLA) using a flexible ruler for the ULA and LLA. Then, after 1 week of resistance footrest exercise designed to strengthen the lumbar spine musculature, we measured these angles again. We measured each angle three times and then compared measurements from before and after exercise. Results: There were no significant differences in the ULA following the strengthening exercise, but significant differences were observed in LLA. Conclusion: The resistance footrest exercise strengthened the muscles affecting the pelvic and lumbar lordotic angles, and increases in the LLA were changed. This suggests that the role of the lower lumbar spine in the lumbar lordotic curve is greater than that of the upper lumbar spine. In addition, considering the contemporary tendency to lead fairly sedentary lives, these results indicate that exercising while seated can be effective.

요통은 산업화된 현대사회에서 흔히 발생하는 질환이다. 요통의 다양한 원인 중에서도 척추의 정상 가동범위를 넘은 불안정성이 요통의 한 원인으로 보고되고 있다. 이 문헌고찰의 목적은 요추 부위의 안정성을 부여하는 운동 프로그램 후 근육 기능의 강화, 통증의 감소를 보고한 논문들을 비교, 분석하는 것이다. 그리하여 요통의 한 원인인 척추의 안정성을 증가시켜 요추 부위의 통증을 감소시키고 기능을 향상시키는 운동 프로그램의 효과를 입증하는 것이다.
