Chronic nonspecific low back pain (CNLBP) is often associated with impaired mobility, functional limitations, and psychological distress. While myofascial release (MFR) and capacitive-resistive therapy (TECAR) have individually shown potential benefits, evidence regarding their combined application is limited. This assessor-blinded, three-arm randomized controlled trial included 67 patients with CNLBP. Participants were assigned to MFR alone, resistive-mode TECAR (R-TECAR) alone, or MFR plus R-TECAR. Interventions were administered twice weekly for 4 weeks, with each session lasting 20 min. Primary outcomes included the Numeric Pain Rating Scale (NPRS) and the Roland-Morris Disability Questionnaire (RMDQ), assessed at the baseline, 4 weeks, and one-and-a-half-month follow-up. Secondary outcomes encompassed thoracolumbar fascia (TLF) thickness, pressure pain threshold (PPT), trunk mobility, quality of life, anxiety, and depression. Intention-to-treat analyses were performed. All interventions yielded significant improvements in pain and disability over time, although the combined MFR + R-TECAR therapy did not achieve statistically significant additional benefits compared with single therapies. Notably, a significant interaction effect emerged for PPT in the right quadratus lumborum muscle (=0.01), with the MFR + R-TECAR group demonstrating greater improvement than R-TECAR alone. Other secondary outcomes, including TLF thickness and psychometric measures, improved over time but showed no significant between-group differences. Combining MFR with R-TECAR for CNLBP did not produce superior outcomes compared with individual treatments though certain muscle-specific benefits were observed. Future research should focus on optimizing treatment parameters, extending intervention and follow-up periods, and exploring individualized approaches to maximize therapeutic efficacy.

慢性非特异性下腰痛（CNLBP）常伴有活动能力受损、功能受限和心理困扰。虽然肌筋膜放松疗法（MFR）和电容电阻疗法（TECAR）各自已显示出潜在益处，但关于它们联合应用的证据有限。这项评估者盲法、三臂随机对照试验纳入了67例CNLBP患者。参与者被分配至单独接受MFR、单独接受电阻模式TECAR（R-TECAR）或MFR加R-TECAR。干预措施每周进行两次，共4周，每次疗程持续20分钟。主要结局包括数字疼痛评分量表（NPRS）和罗兰-莫里斯残疾问卷（RMDQ），在基线、4周和1个半月随访时进行评估。次要结局包括胸腰筋膜（TLF）厚度、压痛阈值（PPT）、躯干活动度、生活质量、焦虑和抑郁。进行了意向性分析。随着时间推移，所有干预措施在疼痛和残疾方面均产生了显著改善，尽管与单一疗法相比，联合MFR + R-TECAR疗法未取得统计学上显著更多的益处。值得注意的是，右侧腰方肌的PPT出现了显著的交互作用效应（=0.01），MFR + R-TECAR组的改善程度大于单独的R-TECAR组。其他次要结局，包括TLF厚度和心理测量指标，随时间有所改善，但组间无显著差异。对于CNLBP，将MFR与R-TECAR联合应用与单独治疗相比并未产生更好的效果，尽管观察到了某些特定肌肉的益处。未来的研究应侧重于优化治疗参数、延长干预和随访时间，并探索个体化方法以最大化治疗效果。中国临床试验注册中心：ChiCTR2400087961。
