The primary objective was to compare non-biomechanical factors between manual workers with and without a history of LBP related to lifting. A secondary objective was to investigate associations between the change in pain intensity during repeated lifting (termed pain ramp) and non-biomechanical factors tested in the LBP group. Manual workers currently in lifting occupations with and without a history of lifting-related LBP were recruited (21 LBP and 20 noLBP) and took part in a repeated (100) lift task. A series of non-biomechanical factors, including psychological, work-related, lifestyle, whole health and psychophysical factors, were collected. Psychophysical factors (pressure pain thresholds (PPTs) and fatigue) were also measured at different time points. Associations between pain ramp during lifting and non-biomechanical factors were investigated with linear regression. The LBP group reported worse perceived sleep quality, more musculoskeletal pain sites other than LBP and greater symptoms related to gastrointestinal complaints and pseudo-neurology compared to the group with no history of LBP. The group with LBP were also slightly more worried about the lifting task and felt more fatigued at the end of the lifting task. The feeling of fatigue during lifting was positively associated with pain ramp in the LBP group. Anxiety and gastrointestinal complaints were weakly negatively associated with pain ramp during lifting. The group differences of poorer perceived sleep, greater non-specific health complaints, slightly more worry about the lifting task and more perceived fatigue in the LBP group highlight the complex and multi-factorial nature of LBP related to lifting. The feeling of fatigue was positively associated with pain ramp in the LBP group, suggesting a close relationship with pain and fatigue during lifting that requires further exploration.
主要目的是比较有和无与提举相关的腰痛病史的体力劳动者之间的非生物力学因素。次要目的是调查在腰痛组中测试的非生物力学因素与反复提举过程中疼痛强度变化（称为疼痛斜坡）之间的关联。目前从事举起重物职业的体力劳动者，无论是否有与提举相关的腰痛病史，均被招募（21 名腰痛和 20 名无腰痛），并参与了重复（100 次）提举任务。收集了一系列非生物力学因素，包括心理、工作相关、生活方式、整体健康和心理物理因素。还在不同时间点测量了心理物理因素（压力疼痛阈值 (PPT) 和疲劳）。使用线性回归调查了提举过程中疼痛斜坡与非生物力学因素之间的关联。腰痛组报告睡眠质量较差，除腰痛外，肌肉骨骼疼痛部位更多，与胃肠道投诉和假性神经病相关的症状更多，与无腰痛病史组相比。腰痛组在提举任务结束时也稍微更担心提举任务，感觉更疲劳。提举过程中的疲劳感与腰痛组的疼痛斜坡呈正相关。焦虑和胃肠道投诉与提举过程中的疼痛斜坡呈弱负相关。腰痛组较差的睡眠感知、更多的非特异性健康投诉、对提举任务的轻微担忧和更多的疲劳感表明，与提举相关的腰痛具有复杂和多因素的性质。腰痛组中疲劳感与疼痛斜坡呈正相关，这表明在提举过程中疼痛和疲劳之间存在密切关系，需要进一步探索。
