Passive spinal stiffness is an important property thought to play a significant role in controlling spinal position and movement. Measuring through-range passive stiffness in vivo is challenging with several methods offered in the literature. Currently, no synthesis of values or methods exists to which to compare literature to. This study aims to provide a contemporary review and quantitative synthesis of the through-range in vivo passive lumbar spinal stiffness values for each of the cardinal planes of movement. A structured systematic search, following PRISMA guidelines, of 28 electronic databases was conducted in 2022. Articles were restricted to peer-reviewed English language studies investigating in vivo through-range passive stiffness of the lumbar spine. Thirteen studies were included, ten relating to flexion/extension, four to lateral bending and five to axial rotation. Average stiffness values, as weighted means and confidence intervals, for each of the four sections of the moment-movement curves were synthesised for all planes of movement. Lateral bending was found to be the comparatively stiffest movement followed by flexion and then axial rotation. Future research should focus on the validity and reliability of measurement techniques. Axial rotation would also benefit from further study of its latter stages of range.
被动脊柱刚度是一种重要的特性，被认为在控制脊柱位置和运动方面起着重要作用。通过几种文献中提供的方法来测量体内的全程被动刚度具有挑战性。目前，尚无用于比较文献的综合值或方法。本研究旨在对每个运动主平面的腰椎全程被动脊柱刚度值进行当代综述和定量综合。2022 年，根据 PRISMA 指南，对 28 个电子数据库进行了有组织的系统检索。文章仅限于调查腰椎全程被动刚度的同行评审的英语语言研究。共纳入 13 项研究，其中 10 项与屈伸有关，4 项与侧屈有关，5 项与旋转有关。对所有运动平面的力矩-运动曲线的四个部分的平均刚度值（作为加权平均值和置信区间）进行了综合。发现侧屈是最僵硬的运动，其次是屈伸，然后是旋转。未来的研究应侧重于测量技术的有效性和可靠性。旋转还应进一步研究其范围的后期阶段。
