摘要

背景：据报道，腰痛患者表现为髋关节和腰伸肌群无力。有腰痛的人可能会以某种方式进行深蹲举，以适应肌肉能力下降。该研究的目的是评估髋关节和腰伸肌力量对腰力矩的影响，在有和没有腰痛的人。方法：50名年龄在18-50岁之间的个体（25名腰痛患者和25名非腰痛患者）参与研究。腰椎和髋部伸肌的力量用电机驱动测功仪测量。在深蹲举重的过程中，腰部和髋部伸肌力矩被量化。研究结果：腰痛患者在深蹲举重时腰伸肌和髋伸肌的平均时刻明显较低。此外，与健康个体相比，腰痛患者的腰伸肌和髋伸肌力量显著降低。在腰痛患者中，腰伸肌力量和腰伸肌力矩（r = 0.40, p = 0.05）以及髋伸肌力量和腰伸肌力矩（r = 0.48, p = 0.02）之间存在显著正相关。在健康组中也发现了类似的关系。解释：患有腰痛的个体在进行深蹲举任务时，腰部力矩减少。下腰椎伸肌力矩与下髋关节和腰椎力量相关，表明肌肉容量可能影响个体的举重策略。

Influence of hip and lumbar extensor strength on lumbar moments during a squat lift: An evaluation of persons with and without low back pain

Background

Individuals with low back pain have been reported to exhibit weakness of the hip and lumbar extensor muscle groups. It is possible that persons with low back pain may perform a squat lift in a manner to accommodate diminished muscular capacity. The objective of the study was to evaluate the influence of hip and lumbar extensor strength on lumbar moments in persons with and without low back pain.

Methods

Fifty individuals (25 with low back pain and 25 without low back pain) between the ages of 18–50 years participated. Strength of the lumbar and hip extensors was measured using a motor-driven dynamometer. Lumbar and hip extensor moments were quantified during the performance of a squat lift.

Findings

On average lumbar extensor and hip extensor moments during the squat lift were significantly lower in those with low back pain. In addition, lumbar extensor and hip extensor strength were significantly lower in those with low back pain compared to healthy individuals. In persons with low back pain, significant positive associations were found between lumbar extensor strength and lumbar extensor moments (r = 0.40, p = 0.05) and hip extensor strength and lumbar extensor moments (r = 0.48, p = 0.02). Similar relationships were found in the healthy group.

Interpretation

Individuals with low back pain performed the squat lift task in a manner that resulted in reduced lumbar moments. Lower lumbar extensor moments were associated with lower hip and lumbar strength, suggesting that muscular capacity may influence an individual's lifting strategy.

期刊介绍： Clinical Biomechanics is an international multidisciplinary journal of biomechanics with a focus on medical and clinical applications of new knowledge in the field. The science of biomechanics helps explain the causes of cell, tissue, organ and body system disorders, and supports clinicians in the diagnosis, prognosis and evaluation of treatment methods and technologies. Clinical Biomechanics aims to strengthen the links between laboratory and clinic by publishing cutting-edge biomechanics research which helps to explain the causes of injury and disease, and which provides evidence contributing to improved clinical management. A rigorous peer review system is employed and every attempt is made to process and publish top-quality papers promptly. Clinical Biomechanics explores all facets of body system, organ, tissue and cell biomechanics, with an emphasis on medical and clinical applications of the basic science aspects. The role of basic science is therefore recognized in a medical or clinical context. The readership of the journal closely reflects its multi-disciplinary contents, being a balance of scientists, engineers and clinicians. The contents are in the form of research papers, brief reports, review papers and correspondence, whilst special interest issues and supplements are published from time to time. Disciplines covered include biomechanics and mechanobiology at all scales, bioengineering and use of tissue engineering and biomaterials for clinical applications, biophysics, as well as biomechanical aspects of medical robotics, ergonomics, physical and occupational therapeutics and rehabilitation.
