Biering-Sorensen test is an isometric back endurance test. Biering-Sorensen test scores have varied in different cultural and occupational groups. The aims of this study were to collect normative data on Biering-Sorensen holding times, to determine the discriminative ability of the Biering-Sorensen test in Turkish coal miners, and to examine the association between Biering-Sorensen test result and functional disability.
One hundred and fifty male coal miners participated in this study. Trunk extensor muscle strength was measured using the Biering-Sorensen test. Oswestry disability index was used to measure the functional disability level of low back pain.
The mean Biering-Sorensen holding time for the total subject group was 107.3+/-22.5s. The mean time of Biering-Sorensen test of the subjects with and without low back pain were 99.9+/-19.8 and 128.6+/-15.2 s, respectively. The difference between the subjects with and without low back pain was statistically significant (p<0.001). There was a statistically significant negative correlation between Oswestry functional disability score and Biering-Sorensen holding time (r=-0.824, p<0.001).
Turkish coal miners have low mean back extensor endurance holding times. Biering-Sorensen test had a good discriminative ability in our study group. Trunk muscle strength has a significant effect on the disability level of low back pain. Thus trunk muscle endurance training exercise therapy may be effective for the reduction of disability in patients with low back pain.
Biering-Sorensen试验是一种等长背部耐力测试。Biering-Sorensen试验得分在不同文化和职业群体中有所不同。本研究的目的是收集Biering-Sorensen保持时间的规范数据，确定Biering-Sorensen试验在土耳其煤矿工人中的鉴别能力，并研究Biering-Sorensen试验结果与功能障碍之间的关联。
150名男性煤矿工人参与了本研究。使用Biering-Sorensen试验测量躯干伸肌力量。采用Oswestry功能障碍指数来测量腰痛的功能障碍水平。
整个受试者组的平均Biering-Sorensen保持时间为107.3±22.5秒。有和没有腰痛的受试者的Biering-Sorensen试验平均时间分别为99.9±19.8秒和128.6±15.2秒。有和没有腰痛的受试者之间的差异具有统计学意义（p<0.001）。Oswestry功能障碍评分与Biering-Sorensen保持时间之间存在统计学意义的负相关（r=-0.824，p<0.001）。
土耳其煤矿工人的背部伸肌平均耐力保持时间较低。Biering-Sorensen试验在我们的研究组中具有良好的鉴别能力。躯干肌肉力量对腰痛的功能障碍水平有显著影响。因此，躯干肌肉耐力训练运动疗法可能对降低腰痛患者的功能障碍有效。
