Of all 30-, 40-, 50-, and 60-year-old inhabitants of Glostrup, a suburb of Copenhagen, 82% (449 men and 479 women) participated in a general health survey, which included a thorough physical examination relating to the lower back. The examination was constituted of anthropometric measurements, flexibility/elasticity measurements of the back and hamstrings, as well as tests for trunk muscle strength and endurance. The reproducibility of the tests was found to be satisfactory. Twelve months after the physical examination 99% of the participants completed a questionnaire sent by mail concerning low back trouble (LBT) in the intervening period. The prognostic value of the physical measurements was evaluated for first-time experience and for recurrence or persistence of LBT by analyses of the separate measurements and discriminant analyses. The main findings were that good isometric endurance of the back muscles may prevent first-time occurrence of LBT in men and that men with hypermobile backs are more liable to contract LBT. Recurrence or persistence of LBT was correlated primarily to the interval since last LBT-episode: the more LBT, the shorter the intervals had been. Weak trunk muscles and reduced flexibility/elasticity of the back and hamstrings were found as residual signs, in particular, among those with recurrence or persistence of LBT in the follow-up year.
在哥本哈根郊区格罗斯特鲁普所有30岁、40岁、50岁和60岁的居民中，82%（449名男性和479名女性）参与了一项全面健康调查，其中包括一次与下背部相关的全面体格检查。该检查包括人体测量、背部和腘绳肌的柔韧性/弹性测量，以及躯干肌肉力量和耐力测试。结果发现这些测试的可重复性令人满意。体检12个月后，99%的参与者完成了一份通过邮件发送的关于在此期间下背部问题（LBT）的问卷。通过对各项单独测量结果的分析和判别分析，评估了体格测量对首次出现LBT以及LBT复发或持续存在的预后价值。主要发现是，背部肌肉良好的等长耐力可能会预防男性首次出现LBT，并且背部活动过度的男性更容易患上LBT。LBT的复发或持续存在主要与自上次LBT发作以来的间隔时间相关：LBT发作次数越多，间隔时间越短。在随访年度中，尤其是在那些LBT复发或持续存在的人群中，发现躯干肌肉无力以及背部和腘绳肌的柔韧性/弹性降低是残留体征。
