Objective

The purpose of the study was to examine the effectiveness of a novel supported dynamic lumbar extension with the abdominal drawing-in maneuver (ADIM) technique on stature change, deep abdominal muscle activity, trunk muscle fatigue, and pain intensity during prolonged sitting in chronic low back pain (CLBP) participants.

Background

Prolonged sitting can cause trunk muscle fatigue from continuous contraction of deep trunk muscles in seated postures. Deficiency of activity of deep muscles can reduce muscular support of the spine, causing stress on spinal structures, which could result in pain.

Method

Thirty participants with CLBP were randomly allocated: (a) control—sitting without exercise, and (b) intervention—supported dynamic lumbar extension with the ADIM technique.

Results

Compared to the intervention condition, the control condition demonstrated significantly greater deterioration in stature change, increased levels of deep trunk muscle fatigue, and an increase in pain during prolonged sitting.

Conclusion

The supported dynamic lumbar extension with the ADIM technique appears to provide a protective effect on detrimental stature change and deep trunk muscle fatigue. In addition, it prevented an increase in pain intensity during prolonged sitting in people with CLBP.

Application

Sedentary behavior harms health, particularly affecting the lower back. Clinicians can use the intervention to induce dynamic lumbar movement, and this exercise can maintain deep trunk muscle activity during prolonged sitting, thereby helping to prevent low back pain (LBP) problems.

对缓解久坐工人慢性腰痛的创新运动的评估

客观的

该研究的目的是检查一种新型支撑式动态腰椎伸展与腹部牵引动作 (ADIM) 技术在长期坐在慢性低位时的身材变化、深部腹部肌肉活动、躯干肌肉疲劳和疼痛强度的有效性。背痛（CLBP）参与者。

背景

久坐会导致躯干肌肉疲劳，原因是深部躯干肌肉在坐姿中持续收缩。深层肌肉活动不足会减少对脊柱的肌肉支撑，对脊柱结构造成压力，从而导致疼痛。

方法

30 名患有 CLBP 的参与者被随机分配：（a）对照组——坐着不运动，（b）干预——使用 ADIM 技术支持动态腰椎伸展。

结果

与干预条件相比，对照条件表现出显着更大的身材变化恶化、深部躯干肌肉疲劳程度增加以及长时间坐着时疼痛增加。

结论

ADIM 技术支持的动态腰椎伸展似乎对有害的身材变化和深部躯干肌肉疲劳提供了保护作用。此外，它还可以防止 CLBP 患者长时间坐着时疼痛强度的增加。

应用

久坐行为危害健康，尤其是影响下背部。临床医生可以使用干预来诱导动态腰椎运动，这种运动可以在长时间坐着时保持深部躯干肌肉活动，从而有助于预防腰痛 (LBP) 问题。
