The skeletal muscles and the fibrous connective tissue form an extensive, body-wide network of myofascial chains. As fascia can modify its stiffness, strain transmission along these meridians is supposable. The goal of this trial therefore was to collect pilot data for potential remote effects of lower limb stretching on cervical range of motion (ROM). Twenty-six healthy participants (30 ± 6 years) were included in the matched-pairs intervention study. One group (n = 13) performed three 30 s bouts of static stretching for the gastrocnemius and the hamstrings, respectively. An age- and sex-matched control group (CG; n = 13) remained inactive. Pre- and post-intervention, maximal cervical ROM in flexion/extension was assessed. A repeated measures ANOVA revealed systematic differences between groups (P < .05). ROM increased following stretching (143.3 ± 13.9 to 148.2 ± 14°; P < .05) but remained unchanged in the CG (144.6 ± 16.8 to 143.3 ± 16.8°; P > .05). Our data point towards existence of a strain transfer along myofascial meridians. Further randomised controlled studies on conditions, factors and magnitude of tensile transmission are warranted.
骨骼肌和纤维结缔组织构成了一个广泛的、遍布全身的肌筋膜链网络。由于筋膜可以改变其僵硬度，因此沿这些经络的应变传递是可以想象的。因此，本试验的目的是收集关于下肢拉伸对颈椎活动范围（ROM）潜在远程影响的初步数据。26名健康参与者（30±6岁）被纳入配对干预研究。一组（n = 13）分别对腓肠肌和腘绳肌进行了3次30秒的静态拉伸。年龄和性别匹配的对照组（CG；n = 13）保持不活动状态。在干预前后，评估颈椎屈伸的最大活动范围。重复测量方差分析显示两组之间存在系统性差异（P <.05）。拉伸后活动范围增加（从143.3±13.9度增加到148.2±14度；P <.05），但对照组保持不变（从144.6±16.8度到143.3±16.8度；P >.05）。我们的数据表明肌筋膜经络上存在应变传递。有必要对拉伸传递的条件、因素和程度进行进一步的随机对照研究。
