摘要

背景：腰痛是一种普遍的全球性疾病，由于80%以上的病例缺乏明确的诊断，往往难以解决。在许多工作环境中，手工举重很常见，由于腰椎的压力会导致腰痛，而现有的辅助技术，如腹带和外骨骼，在有效管理腰痛方面存在局限性。本文介绍了一种新的背部支撑装置，该装置设计用于在屈曲活动中产生腹部压迫，通过增加腹内压力来潜在地增强腰椎稳定性。方法：研究包括14名慢性非特异性腰痛患者和18名性别匹配的健康对照者，他们分别在使用和不使用支持装置的情况下进行控制运动测试。结果表明，在各种功能任务中，背部支撑装置增加了两组的腹内压力，特别是在主动屈曲和抬起任务中（高达43%）。该装置还有助于减少引导屈曲时腰椎的活动范围（- 18%至- 37%，腰骶交界处除外），强调其在限制过度脊柱运动方面的潜在影响。肌肉活动评估显示，佩戴该装置时，在主动屈曲和抬起运动中，肌肉活动减少，这表明在没有相应的对抗性肌肉活动和脊柱相关压缩负荷的情况下，有可能帮助躯干稳定。解释：这些效果可以帮助工人保持他们在工作场所的活动，并帮助患有腰痛的工人逐渐重新融入工作或体育活动，有助于更好地全面管理背部健康。

Feasibility of a novel back support device to improve spine stability and muscular activity during trunk flexion: A prospective cross-sectional study with healthy controls and low back pain subjects - preliminary

Background

Low back pain is a prevalent global condition often challenging to address due to the absence of a definitive diagnosis in over 80 % of cases. Manual lifting, common in many work environments, contributes to low back pain due to lumbar spine stresses, and existing assistive technologies like abdominal belts and exoskeletons have limitations in managing low back pain effectively. This paper presents a novel back support device designed to generate abdominal compression during flexion activities, potentially enhancing lumbar stability through increased intra-abdominal pressure.

Methods

The study involved 14 participants with chronic non-specific low back pain and 18 gender-matched healthy controls doing controlled movement tests with and without the support device.

Findings

Results suggest that the back support device increased intra-abdominal pressure in both groups during various functional tasks, more notably in active flexion and lifting tasks (up to +43 %). The device also contributed to decreasing lumbar range of motion during guided flexion (−18 to −37 %, except at the lumbosacral junction in the low back pain group), emphasizing its potential impact in limiting excessive spinal movement. Muscle activity assessments revealed decreased activation during active flexion and lifting movements while wearing the device, suggesting the possibility to assist trunk stabilization without the corresponding antagonistic muscle activation and associated compressive load on the spine.

Interpretation

These effects could help workers to maintain their activities in the workplace and help workers suffering from low back pain to gradually reintegrate work or physical activities, contributing to better overall management of back health.

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.
