研究表明，在一些腰痛患者中，腰椎带（LB）可能会产生二级预防效益。然而，仍有待确定的是，哪些患者最有可能从预防性LB使用中受益，以及哪种LB设计最适合于此目的。本研究的目的是确定不同腰椎带设计对活动范围和腰盆节律的影响。健康受试者（10名男性; 10名女性）在对照（无腰带）和四种腰带实验条件（可伸展，有和没有背面板和腹面板;不可伸展）期间，膝盖伸直，进行了五次站立腰部屈曲/伸展循环。骨盆和腰椎的运动用3D角惯性传感器测量。结果表明，增加背侧和腹侧面板的可扩展LB产生最大的腰椎限制之间的四个测试的腰部带设计，这反过来也改变了腰骨盆的节奏。在更探索性的基础上，观察到一些性别差异，性别×实验条件的相互作用未能达到显著性。LB可以为患有下背部疾病的患者提供一些生物力学益处，基于可以针对基于软组织蠕变的损伤机制提供的保护。然而，必须首先对不同的LB设计进行更全面的评估，并进行额外的心理和神经肌肉测量结果，以便为LB的使用提供合理的建议。未来的研究还应考虑到性别因素，并有足够的统计能力来明确反驳或证实观察到的趋势。本文的在线版本（doi：10.1186/1471-2474-15-307）包含补充材料，可供授权用户使用。
Research suggests that in some patients with low back pain, lumbar belts (LB) may derive secondary prophylactic benefits. It remains to be determined, however, which patients are most likely to benefit from prophylactic LB use, and which LB design is optimal for this purpose. The objective of this study was to determine the effect of different lumbar belts designs on range of motion and lumbopelvic rhythm. Healthy subjects (10 males; 10 females) performed five standing lumbar flexion/extension cycles, with knees straight, during a control (no belt) and four lumbar belt experimental conditions (extensible, with and without dorsal and ventral panels; non-extensible). Motion of the pelvis and lumbar spine was measured with 3D angular inertial sensors. The results suggest that adding dorsal and ventral panels to an extensible LB produces the largest lumbar spine restrictions among the four tested lumbar belt designs, which in turn also altered the lumbopelvic rhythm. On a more exploratory basis, some sex differences were seen and the sex × experimental condition interaction just failed to reach significance. LB may provide some biomechanical benefit for patients with low back disorders, based on the protection that may be provided against soft tissue creep-based injury mechanisms. More comprehensive assessment of different LB designs, with additional psychological and neuromuscular measurement outcomes, however, must first be conducted in order to produce sound recommendations for LB use. Future research should also to take sex into account, with sufficient statistical power to clearly refute or confirm the observed trends.
