Several studies have shown a higher prevalence of radiological abnormalities among gymnasts. However, the types of radiological abnormalities associated with low back pain (LBP) have not been clarified. The hypothesis was that significant relationships between radiological abnormalities and LBP may be revealed by discriminating between the types of MRI abnormalities while considering confounding factors. The subjects were 104 Japanese collegiate gymnasts (men, 70; women, 34). The presence of LBP was evaluated using the questionnaire developed by Osaka City University (OCU Test). Magnetic resonance imaging (MRI) abnormalities were evaluated using T1- and T2-weighted MRI. The prevalence of more than 1 MRI abnormality in gymnasts was 47.1% (49/104). The chi-square test showed that the incidence of lumbar disc degeneration (LDDG) and limbus vertebra was significantly greater in gymnasts with LBP than in gymnasts without LBP. By using logistic regression analysis to analyze the concomitant environmental variables, only LDDG (odds ratio, 2.70; 95% confidence interval, 1.10-6.66) was selected as a statistically significant variable accounting for LBP. In conclusion, LDDG is a predictor for LBP in Japanese collegiate gymnasts.
几项研究表明,体操运动员的影像学异常发生率较高。然而,与下腰痛(LBP)相关的影像学异常类型尚不清楚。假设通过区分 MRI 异常的类型,并考虑混杂因素,可以揭示影像学异常与 LBP 之间的显著关系。研究对象为 104 名日本大学生体操运动员(男性 70 名,女性 34 名)。使用大阪城市大学(OCU 测试)开发的问卷评估 LBP 的存在。使用 T1 和 T2 加权 MRI 评估磁共振成像(MRI)异常。体操运动员中存在 1 种以上 MRI 异常的比例为 47.1%(49/104)。卡方检验显示,有 LBP 的体操运动员腰椎间盘退变(LDDG)和椎弓根骨突的发生率明显高于无 LBP 的体操运动员。通过使用逻辑回归分析来分析伴随的环境变量,只有 LDDG(优势比,2.70;95%置信区间,1.10-6.66)被选为统计学上显著的变量,可解释 LBP。综上所述,LDDG 是日本大学生体操运动员 LBP 的预测因子。
