Abstract

Background: Trunk co-contraction during lifting may reflect a guarded motor response to a threatening task. This work estimated the impact of pain catastrophizing on trunk co-contraction during lifting, in people with and without low back pain.

Methods: Adults with high pain catastrophizing (back pain: n = 29, healthy: n = 7) and low pain catastrophizing (back pain: n = 20, healthy: n = 11), performed 10 repetitions of a lifting task. Electromyography data of rectus abdominis, erector spinae and external oblique muscles were collected, bilaterally. Co-contraction indices were determined for rectus abdominis/erector spinae and external oblique/erector spinae pairings, bilaterally. Pain catastrophizing was measured using the pain catastrophizing scale and task-specific fear using the Photograph series of daily activities scale. Three-way mixed ANOVAs tested the effects of group (back pain vs. healthy), pain catastrophizing (high vs. low), lifting phase (lifting vs. replacing) and their interactions.

Results: There were no main effects of pain catastrophizing, lifting phase, nor any interactions (p > 0.05). Group effects revealed greater co-contraction for bilateral erector spinae/rectus abdominis pairings (but not erector spinae-external oblique pairings) in people with back pain, compared to healthy participants, independent of pain catastrophizing and lifting phase (p < 0.05). Spearman correlations associated greater task-specific fear and greater erector spinae-left external oblique co-contraction, only in people with back pain (p < 0.05).

Conclusions: Greater co-contraction in the back pain group occurred independent of pain catastrophizing, as measured with a general questionnaire. A task-specific measure of threat may be more sensitive to detecting relationships between threat and co-contraction.

Significance statement: This work contributes evidence that people with back pain commonly exhibit trunk co-contraction when lifting. The lack of a relationship between pain catastrophizing and trunk co-contraction, however, challenges evidence linking psychological factors and guarded motor behaviour in this group. Together, this suggests that other factors may be stronger determinants of co-contraction in people with LBP or that a general construct like pain catastrophizing may not accurately represent this relationship.

慢性腰痛患者和非慢性腰痛患者在提举过程中的疼痛灾难化和躯干共同收缩:一项横断面研究。
背景:提举过程中的躯干共同收缩可能反映了对威胁性任务的警惕性运动反应。这项研究估计了疼痛灾难化对腰背痛患者和非腰背痛患者在提举过程中躯干共同收缩的影响:方法:疼痛灾难化程度高(腰痛:29 人,健康:7 人)和疼痛灾难化程度低(腰痛:20 人,健康:11 人)的成年人重复 10 次举重任务。收集了双侧腹直肌、竖脊肌和腹外斜肌的肌电图数据。测定了双侧腹直肌、竖脊肌和外斜肌/竖脊肌的协同收缩指数。疼痛灾难化量表测量疼痛灾难化程度,摄影系列日常活动量表测量任务特定恐惧程度。三方混合方差分析测试了组别(背痛与健康)、疼痛灾难化程度(高与低)、抬起阶段(抬起与替换)及其交互作用的影响:结果:疼痛灾难化、移位阶段和交互作用均无主效应(P > 0.05)。组间效应显示,与健康参与者相比,背痛患者的双侧竖脊肌/腹直肌配对(但不包括竖脊肌-腹外斜肌配对)的共收缩更大,这与疼痛灾难化和抬举阶段无关(P 结论:背痛患者的共收缩更大,这与疼痛灾难化和抬举阶段无关:背痛组患者的共收缩能力更强,这与疼痛灾难化程度无关,疼痛灾难化程度通过普通问卷进行测量。针对特定任务的威胁测量可能对检测威胁与共同收缩之间的关系更为敏感:这项研究提供的证据表明,背痛患者在提举时通常会表现出躯干共同收缩。然而,疼痛灾难化与躯干共同收缩之间缺乏关系,这对该群体中将心理因素与戒备性运动行为联系起来的证据提出了质疑。总之,这表明其他因素可能是腰背痛患者躯干共同收缩的更有力的决定因素,或者像疼痛灾难化这样的一般概念可能并不能准确地代表这种关系。

期刊介绍: European Journal of Pain (EJP) publishes clinical and basic science research papers relevant to all aspects of pain and its management, including specialties such as anaesthesia, dentistry, neurology and neurosurgery, orthopaedics, palliative care, pharmacology, physiology, psychiatry, psychology and rehabilitation; socio-economic aspects of pain are also covered. Regular sections in the journal are as follows: • Editorials and Commentaries • Position Papers and Guidelines • Reviews • Original Articles • Letters • Bookshelf The journal particularly welcomes clinical trials, which are published on an occasional basis. Research articles are published under the following subject headings: • Neurobiology • Neurology • Experimental Pharmacology • Clinical Pharmacology • Psychology • Behavioural Therapy • Epidemiology • Cancer Pain • Acute Pain • Clinical Trials.
