Abstract

STUDY DESIGN

Cross-sectional study of a specific population.

OBJECTIVES

To investigate the prevalence and coprevalence of nonspecific low back pain (nsLBP) and lumbar radiological abnormalities (LRA) in judo athletes.

BACKGROUND

nsLBP and LRA occur frequently in judo athletes. High body mass has been reported to be associated with both nsLBP and LRA.

METHODS AND MEASURES

The subjects comprised 82 male judo athletes (mean +/- SD age, 20.1 +/- 0.9 years) from 3 weight categories: lightweight (n = 29), middleweight (n= 31), and heavyweight (n = 22). The presence of nsLBP was evaluated using a questionnaire. LRA were examined using plain-film radiographs and magnetic resonance imaging. The prevalence of nsLBP and LRA were compared among weight categories.

RESULTS

The prevalence of nsLBP in the lightweight, middleweight, and heavyweight categories was 34.5%, 32.3%, and 40.9%, respectively. For LRA, prevalence for the 3 weight categories was 65.5%, 90.3%, and 90.9%, respectively (middle-weight and heavyweight greater prevalence than lightweight [P<.05]). The prevalence of LRA in athletes with nsLBP in each category was 50.0%, 100%, and 88.9%, respectively (middleweight greater prevalence than lightweight [P<.05]). The prevalence of LRA in athletes without nsLBP in each category was 73.7%, 85.7%, and 92.3%, respectively.

CONCLUSIONS

The prevalence of LRA was approximately 90% in the middleweight and heavyweight categories, which was greater than for the lightweight category. There was a large coprevalence of nsLBP and LRA. However, many judo athletes without nsLBP had LRA. The presence of LRA may not have a direct association with nsLBP.

摘要

研究设计

针对特定人群的横断面研究。

目的

调查柔道运动员中非特异性下背痛（nsLBP）和腰椎放射学异常（LRA）的患病率及共患病率。

背景

nsLBP和LRA在柔道运动员中频繁出现。据报道，高体重与nsLBP和LRA均有关联。

方法与测量

研究对象包括82名来自3个体重级别的男性柔道运动员（平均年龄±标准差，20.1±0.9岁）：轻量级（n = 29）、中量级（n = 31）和重量级（n = 22）。使用问卷评估nsLBP的存在情况。通过X线平片和磁共振成像检查LRA。比较不同体重级别中nsLBP和LRA的患病率。

结果

轻量级、中量级和重量级中nsLBP的患病率分别为34.5%、32.3%和40.9%。对于LRA，3个体重级别的患病率分别为65.5%、90.3%和90.9%（中量级和重量级的患病率高于轻量级[P<0.05]）。每个级别中患有nsLBP的运动员中LRA的患病率分别为50.0%、100%和88.9%（中量级的患病率高于轻量级[P<0.05]）。每个级别中无nsLBP的运动员中LRA的患病率分别为73.7%、85.7%和92.3%。

结论

中量级和重量级中LRA的患病率约为90%，高于轻量级。nsLBP和LRA的共患病率较高。然而，许多没有nsLBP的柔道运动员存在LRA。LRA的存在可能与nsLBP没有直接关联。
