This study was conducted to determine the effect of muscle energy technique (MET) on pelvic alignment, leg length, pain, and fatigue in chronic low back pain (CLBP) patients with leg length discrepancy (LLD). Forty-two CLBP patients with LLD volunteered to participate and were randomly assigned to the MET group ( = 21) and placebo group ( = 21). The intervention group performed three METs with 5 s of isometric contraction and 30 s of rest once, and the placebo group performed three times the placebo-MET, maintaining the same posture as the MET group without muscle isometric contraction. X-ray equipment, tape measure, and visual analog scale were used to evaluate pelvic alignment, leg length, pain, and fatigue before and after each intervention. In comparison pre- and postintervention, only the MET group showed significant changes in pelvic alignment, leg length, pain, and fatigue ( < 0.05). In comparison between groups, there were significant differences in all variables (pelvic alignment, leg length, pain, fatigue) ( < 0.05). The results of this study confirmed the therapeutic effect of MET for improving pelvic alignment, functional LLD, pain, and fatigue in CLBP patients with functional LLD. Future research is needed to evaluate the long-term effect on more chronic low back pain patients.
本研究旨在确定肌肉能量技术（MET）对存在腿长差异（LLD）的慢性下腰痛（CLBP）患者的骨盆排列、腿长、疼痛和疲劳的影响。42名存在LLD的CLBP患者自愿参与，被随机分为MET组（n = 21）和安慰剂组（n = 21）。干预组进行三次MET，等长收缩5秒，休息30秒，重复一次，安慰剂组进行三次安慰剂-MET，保持与MET组相同的姿势但无肌肉等长收缩。在每次干预前后，使用X射线设备、卷尺和视觉模拟量表评估骨盆排列、腿长、疼痛和疲劳。与干预前相比，只有MET组在骨盆排列、腿长、疼痛和疲劳方面有显著变化（P < 0.05）。在组间比较中，所有变量（骨盆排列、腿长、疼痛、疲劳）均有显著差异（P < 0.05）。本研究结果证实了MET对改善存在功能性LLD的CLBP患者的骨盆排列、功能性LLD、疼痛和疲劳的治疗效果。未来需要进行研究以评估对更多慢性下腰痛患者的长期影响。
