Hamstring strain (HS) is a common musculoskeletal condition and abnormal neurodynamics has been shown to influence HS and delay recovery. The efficacy of stretching for preventing and treating HS remains uncertain despite extensive research and wide-spread use. The effects of cervical spine mobilisation on peripheral nervous system function, neurodynamics and muscle force in the upper limb have been reported. Very few studies have reported effects of lumbar spine mobilisation on these variables in the lower limb. This study aimed to determine immediate effects of either a unilateral zygopophyseal joint posteroanterior mobilisation or a static posterior chain muscle stretch on the range of passive straight leg raise (SLR) in comparison to a non-treatment control. Using a single-blinded, randomised controlled study design, 36 healthy participants were allocated into one of three groups (control; mobilisation; static posterior chain muscle stretch). Measures of SLR were taken before and after intervention for each group on the day of testing. A General Linear Model (GLM) and a paired sample t-test showed a significant difference between base line and post-intervention for the mobilisation group only (p < 0.001), and suggests that unilateral lumbar spine zygopophyseal joint mobilisation can immediately restore posterior chain neurodynamics.
腘绳肌拉伤（HS）是一种常见的肌肉骨骼疾病，研究表明异常的神经动力学可影响HS并延迟恢复。尽管进行了广泛的研究且应用广泛，但拉伸预防和治疗HS的效果仍不确定。已有研究报道了颈椎松动术对上肢周围神经系统功能、神经动力学和肌肉力量的影响。很少有研究报道腰椎松动术对下肢这些变量的影响。本研究旨在比较与非治疗对照组相比，单侧关节突关节后前向松动术或静态后链肌肉拉伸对被动直腿抬高（SLR）范围的即时影响。采用单盲随机对照研究设计，将36名健康参与者分为三组之一（对照组；松动术组；静态后链肌肉拉伸组）。在测试当天，对每组干预前后进行SLR测量。一般线性模型（GLM）和配对样本t检验显示，仅松动术组基线与干预后存在显著差异（p<0.001），提示单侧腰椎关节突关节松动术可立即恢复后链神经动力学。
