概括
过渡性腰痛 (LBP) 与办公室工作期间的坐时间增加和脊柱运动减少有关. 干预措施应侧重于减少坐着的时间和鼓励运动,以减轻LBP风险.
科学领域:
- 职业健康 职业健康 职业健康 职业健康
- 生物力学 生物力学
- 肌肉骨系统疾病 肌肉骨系统疾病
背景情况:
- 在办公室工作者中,长时间坐着,脊柱运动和腰部疼痛 (LBP) 之间的关系尚未完全理解.
- 过渡性腰痛,以每日波动和恢复为特征,提供了一个独特的模型来研究与坐姿相关的疼痛机制.
研究的目的:
- 调查在日常活动和脊柱动力学中发生过渡性LBP的个体与在典型工作周中没有发生过渡性LBP的个体之间的差异.
- 确定与坐姿相关的生物力学因素,这些因素可能有助于LBP的发展.
主要方法:
- 20名办公室工作人员根据视觉模拟尺度疼痛评级被分为非疼痛开发者 (NPD) 或疼痛开发者 (PD).
- 三轴加速度计监测了坐着时间和脊柱角度 (胸部,骨盆,腰部).
- 广度概率分布函数 (APDF) 分析了姿势和运动模式.
主要成果:
- 疼痛发展者 (PD) 比非疼痛发展者 (NPD) 坐得更多.
- 患有PD的患者表现出较低的峰值后骨盆倾斜和胸部倾斜,脊柱运动较少频繁.
- 患PD的疼痛不会在一周内累积,显示每日波动和恢复.
结论:
- 脊柱运动减少和坐时间增加与办公室工作者的过渡性LBP有关.
- 建议包括减少坐着的时间,利用座椅背靠背,并在坐着工作时促进运动.
- 微妙的生物力学差异可能表明,随着时间的推移,与坐姿相关的LBP的发展途径.

01:16Vertebral Column: Regions and Curvature
The vertebral column or spine is a flexible column that supports the head, neck, and body and allows for their movements. It also protects the spinal cord.
Regions of the Vertebral Column
In an adult, the spine is subdivided into five regions: the cervical, the thoracic, the lumbar, the sacral, and the coccygeal region. The spine initially develops as a series of 33 vertebrae; after 20 years of age, the nine bones in the sacral region, five sacral, and four coccygeal bones fuse to form the...

01:29Herniated Intervertebral Disc l: Introduction
Intervertebral disc herniation refers to the displacement of the nucleus pulposus (the gel-like inner core of the disc) through a tear or weakened area in the annulus fibrosus (the outer fibrous ring). The displaced disc material extends beyond the normal boundaries of the disc space and may compress or irritate nearby spinal nerve roots or, less commonly, the spinal cord.Etiology and Risk FactorsHerniation commonly results from degeneration, in which aging reduces disc hydration and...
