Abnormal posture creates abnormal stress and strain in many spinal structures which are considered predisposing factors for chronic mechanical low back pain.
To examine the relationships among pain intensity, forward head posture (decreased craniovertebral angle) and lumbopelvic sagittal alignment (pelvic incidence, pelvic tilt, sacral slope, and lumbar lordosis) in chronic mechanical low back pain patients.
A cross-section correlational study was conducted on one hundred patients. A numerical-pain-rating scale was used to determine pain intensity. Standardized standing lateral radiographs were analyzed to measure the spinopelvic angles. Reported data were analyzed using correlation coefficients, and regression analyses.
Lumbar lordosis had very strong positive correlations with each pain intensity and sacral slope. Pain intensity had a strong positive correlation with sacral slope. Moderate positive correlations highlighted between pelvic tilt and craniovertebral angle. Moreover, the pelvic incidence had weak positive correlations with each sacral slope and pelvic tilt. Negative correlations were strong between pelvic tilt and each of pain intensity, lumbar lordosis and sacral slope. Craniovertebral angle had moderate negative correlations with each of pain, lumbar lordosis, and sacral slope. However, the pelvic incidence had no relations with pain, craniovertebral angle lumbar lordosis. Overall, an association of demographic data and measured variables had a significant effect on the pain multi-regression equation prediction model. They accounted for 76.60% of the variation in pain.
Abnormal spinopelvic posture relates to chronic mechanical low back pain. There are significant associations among pain intensity, FHP and lumbopelvic sagittal alignment in chronic mechanical low back pain patients.
异常姿势会给许多脊柱结构带来异常的压力和应变，这些结构被认为是慢性机械性腰痛的潜在因素。
探讨慢性机械性腰痛患者疼痛强度、前伸头位（头-颈矢状角减小）与腰骶矢状面排列（骨盆入射角、骨盆倾斜度、骶骨倾斜度和腰椎前凸）之间的关系。
对 100 例患者进行横断面相关性研究。采用数字疼痛评分量表来确定疼痛强度。对标准站立侧位 X 线片进行分析，以测量脊柱骨盆角度。使用相关系数和回归分析来分析报告的数据。
腰椎前凸与每个疼痛强度和骶骨斜率均呈很强的正相关。疼痛强度与骶骨斜率呈很强的正相关。骨盆倾斜度与头-颈矢状角之间呈中度正相关。此外，骨盆入射角与每个骶骨斜率和骨盆倾斜度均呈弱正相关。骨盆倾斜度与疼痛强度、腰椎前凸和骶骨斜率均呈很强的负相关。头-颈矢状角与每个疼痛、腰椎前凸和骶骨斜率均呈中度负相关。然而，骨盆入射角与疼痛、头-颈矢状角和腰椎前凸均无相关性。总体而言，人口统计学数据和测量变量的综合作用对疼痛多元回归方程预测模型有显著影响。它们解释了疼痛变异的 76.60%。
异常的脊柱骨盆姿势与慢性机械性腰痛有关。在慢性机械性腰痛患者中，疼痛强度、前伸头位和腰骶矢状面排列之间存在显著关联。
