Abstract This study examined associations and changes overtime in low back kinematics and disability, pain, pain catastrophizing, and depression and assessed whether associations and changes overtime varied between individuals who meet the classification criteria for chronic low back pain at 6 months and those who do not. Findings suggested that those persons with a higher ratio of lumbar contribution to thorax motion and smaller pelvic tilt during forward bending had higher scores on measures of disability, pain and pain catastrophizing. This same association was found in those who met classification criteria for chronic low back pain at 6 months. Opposing associations were found in the group not meeting classification criteria for chronic low back pain, specifically, increased pelvic tilt was positively associated with higher pain catastrophizing scores. Practitioner summary This study examined associations and changes overtime in low back kinematics and psychosocial and clinical factors and whether associations and changes overtime varied between individuals who meet the classification criteria for chronic low back pain at 6 months and those who do not, Results suggest that associations exist between psychological factors and kinematic changes during the time between an acute low back pain episode to meeting classification for chronic low back pain at 6 months.

非慢性腰痛患者腰-盆腔协调性指标与疼痛、残疾、疼痛灾难性和抑郁的关系

摘要本研究检查了腰背运动学和残疾、疼痛、灾难性疼痛和抑郁的关联和加班变化，并评估了在 6 个月时符合慢性腰痛分类标准的个体和不符合慢性腰痛分类标准的个体之间的关联和加班变化是否存在差异。 . 研究结果表明，那些腰椎对胸部运动的贡献率较高且在向前弯曲时骨盆倾斜较小的人在残疾、疼痛和疼痛灾难性测量方面的得分较高。在 6 个月时符合慢性腰痛分类标准的人中也发现了同样的关联。在不符合慢性腰痛分类标准的组中发现了相反的关联，特别是，骨盆倾斜度增加与更高的疼痛灾难评分呈正相关。从业者总结 本研究检查了腰背运动学和心理社会和临床因素的关联和加班变化，以及在 6 个月时符合慢性腰痛分类标准的个体和不符合分类标准的个体之间的关联和加班变化是否不同，结果表明关联在急性腰痛发作到 6 个月时达到慢性腰痛分类之间的时间里，心理因素和运动学变化之间存在差异。
