Excessive foot pronation has been reported as being related to chronic low back pain symptoms and risk factors in sports-specific pathologies. Compensating custom-made foot orthotics treatment has not been entirely explored as an effective therapy for chronic low back pain (CLBP). This study aims to observe the effects of custom-made foot orthoses, in subjects with foot pronation suffering from CLBP. A total of 101 patients with nonspecific CLBP and a pronated foot posture index (FPI) were studied. They were randomized in two groups: an experimental one ( = 53) used custom-made foot orthotics, and the control group ( = 48) were treated with non-biomechanical effect orthoses. The CLBP was measured using the Oswestry Disability Index (ODI) Questionnaire and a visual analogue scale (VAS), both for lower back pain. The symptoms were evaluated twice, at first when the subject was included in the study, and later, after 4 weeks of treatment. The analysis of outcomes showed a significant decrease in CLBP in the custom-made foot orthoses participants group ( < 0.001 ODI; < 0.001 VAS). These findings suggest that controlling excessive foot pronation by using custom-made foot orthoses may significantly contribute to improving CLBP.
过度的足内翻已被报道与慢性下背痛症状和运动特异性病理学的风险因素有关。补偿性定制足垫治疗尚未完全被探索为慢性下背痛（CLBP）的有效治疗方法。本研究旨在观察定制足垫对患有 CLBP 的足内翻患者的影响。共有 101 名非特异性 CLBP 和足内翻足姿势指数（FPI）的患者参与了研究。他们被随机分为两组：实验组（n=53）使用定制足垫，对照组（n=48）使用非生物力学效应足垫。使用 Oswestry 残疾指数（ODI）问卷和视觉模拟量表（VAS）测量 CLBP，两者均用于下背痛。在研究开始时和治疗 4 周后对症状进行了两次评估。结果分析显示，定制足垫组的 CLBP 显著降低（ODI<0.001；VAS<0.001）。这些发现表明，通过使用定制足垫控制过度的足内翻可能显著有助于改善 CLBP。
