背景资料：研究脊柱刚度评估中的后前（PA）力的研究显示了与脊柱水平、体型和腰伸肌活动的关系。这些措施可能是区分无症状患者和腰痛患者的重要决定因素。然而，很少有客观证据表明，PA刚度的变化，其临床意义。此外，尽管一些研究仅评估了与刚度有关的载荷输入，但基于动态刚度测量的更完整的评估（力/速度）和伴随的神经肌肉反应可以提供更多关于下背部力学特性的信息。目的：确定有症状的下背部的刚度和神经肌肉特性。研究设计：本研究是一项前瞻性临床研究，旨在调查患有腰痛（LBP）的研究受试者的人体腰椎节段对高负荷率PA手法推力的体内力学和肌肉行为。12名男性和10名女性，年龄15 - 73岁（平均年龄42.8 ± 17.5岁），接受体格检查并完成结局评估工具，包括视觉模拟量表、奥斯韦斯特里下背部残疾指数和SF-36健康状况问卷。临床分类是根据症状频率和LBP病史进行的。一个手持脊柱操作装置，配备了一个预载控制框架和阻抗头，用于提供高速率（
Background: Studies investigating posteroanterior (PA) forces in spinal stiffness assessment have shown relationships to spinal level, body type, and lumbar extensor muscle activity. Such measures may be important determinants in discriminating between patients who are asymptomatic and those who have low back pain. However, little objective evidence is available concerning, variations in PA stiffness their clinical significance. Moreover, although several studies have assessed only load input in relation to stiffness, a more complete assessment based on dynamic stiffness measurements (force/velocity) and concomitant neuromuscular response may offer more information concerning mechanical properties of the low back.Objective: To determine the stiffness and neuromuscular characteristics of the symptomatic low back.Study Design: This study is a prospective clinical study investigating the in vivo mechanical and muscular behavior of human lumbar spinal segments to high loading rate PA manipulative thrusts in research subjects with low back pain (LBP).Methods: Twelve men and 10 women, aged 15 to 73 years (mean age of 42.8 +/- 17.5 years) underwent physical examination and completed outcome assessment instruments, including Visual Analog Scale, Oswestry Low Back Disability Index, and SF-36 health status questionnaires. Clinical categorization was made on the basis of symptom frequency and LBP history. A hand-held spinal manipulation device, equipped with a preload control frame and impedance head, was used to deliver high-rate (
