Many studies have shown that changes in lumbar flexion angle and the pelvic inclination angle can be affected by the shortening of the lumbar muscles, which can cause low back pain. Decreased lumbar flexion angle and pelvic inclination angle can cause or exacerbate low back pain by disrupting the lumbo-pelvic rhythm.
This study aimed to use myofascial release techniques as a specialized treatment on muscle tissue to cause muscles to reach the optimal length and improve lumbar flexion angle and pelvic inclination angle, and thus improve low-back pain.
Non-specific low back pain patients, Tarbiat Modares University, Iran.
30 chronic non-specific low back pain participants were randomly assigned into two groups.
This is a randomized control trial.
The myofascial release group (n=15) underwent 4 sessions of myofascial release treatment based on Myer's techniques, and the control group (n=15) underwent 10 sessions of routine electrotherapy for two weeks.
Before starting the intervention and after the last treatment session, both groups were evaluated by the lumbar flexion angle with a flexible ruler, calculating the pelvic inclination angle by a trigonometric formula, and VAS measured the pain score of the participants.
The results of the paired t test showed that, after treatment in both groups, the severity of pain and lumbar flexion angle changed significantly ( ≤ .001). However, the pelvic inclination angle was changed considerably only in the myofascial release group, and we did not see significant changes in the control group ( = .082). Also, the independent sample t test results to examine the between-group changes showed that changes in the myofascial release group were significantly different from the control group ( ≤ .000). Also, the effect size shows the large effect of the myofascial release technique compared to the control group (effect size ≥ 1.85).
The present study results showed that myofascial release techniques in patients with low back pain could help decrease pain intensity and increase lumbar flexion and pelvic inclination angle. Based on the present study results, myofascial release can be a treatment to correct posture in patients with chronic non-specific, low back pain. Due to the prevalence of the COVID-19 pandemic, it was not possible to evaluate the long-term effects of treatment.
许多研究表明，腰椎肌肉缩短会影响腰椎前屈角度和骨盆倾斜角度的变化，进而导致腰痛。腰椎前屈角度和骨盆倾斜角度的减小会破坏腰骨盆节律，从而引发或加剧腰痛。
本研究旨在运用肌筋膜放松技术对肌肉组织进行专门治疗，使肌肉达到最佳长度，改善腰椎前屈角度和骨盆倾斜角度，从而缓解腰痛。
伊朗塔比阿特莫达雷斯大学的非特异性腰痛患者。
30名慢性非特异性腰痛参与者被随机分为两组。
这是一项随机对照试验。
肌筋膜放松组（n = 15）接受基于迈尔技术的4次肌筋膜放松治疗，对照组（n = 15）接受为期两周的10次常规电疗。
在干预开始前和最后一次治疗后，两组均使用软尺测量腰椎前屈角度，通过三角公式计算骨盆倾斜角度，并使用视觉模拟评分法（VAS）测量参与者的疼痛评分。
配对t检验结果显示，两组治疗后，疼痛严重程度和腰椎前屈角度均有显著变化（P≤.001）。然而，仅肌筋膜放松组的骨盆倾斜角度有显著变化，对照组未见显著变化（P =.082）。此外，用于检验组间变化的独立样本t检验结果显示，肌筋膜放松组的变化与对照组有显著差异（P≤.000）。而且，效应量表明与对照组相比，肌筋膜放松技术的效果显著（效应量≥1.85）。
本研究结果表明，肌筋膜放松技术可帮助腰痛患者减轻疼痛强度，增加腰椎前屈和骨盆倾斜角度。基于本研究结果，肌筋膜放松可作为慢性非特异性腰痛患者纠正姿势的一种治疗方法。由于新冠疫情流行，无法评估治疗的长期效果。
