Muscular tightness and the therapeutic effect of stretching has been widely discussed during the last few years in sports training and physiotherapy. Within a prospective study of back function and pain before and after compulsory military service, tightness of hamstring- and psoas muscles was assessed. Around 600 young men were examined three times over a period of four years. Tight hamstring muscles were found to be very common in this group. Only 43% of the right and 35% of the left legs reached an angle of at least 80 degrees from the couch during the straight-leg-raising test (Lasegue's test). The test of muscular tightness showed a significant test-retest reliability over all examinations. Tight hamstring- or psoas muscles could not be shown to correlate to current back pain or to the incidence of back pain during the follow-up period.
在过去几年中，肌肉紧张度和拉伸疗法的效果在体育训练和物理治疗领域得到了广泛讨论。在一项关于义务兵役前后背部功能和疼痛的前瞻性研究中，对腘绳肌和腰大肌的紧张度进行了评估。在四年的时间里，对大约600名年轻男性进行了三次检查。结果发现，该组中腘绳肌紧张非常普遍。在直腿抬高试验（拉塞格试验）中，只有43%的右腿和35%的左腿与床面的夹角至少达到80度。肌肉紧张度测试在所有检查中显示出显著的重测信度。在随访期间，未发现腘绳肌或腰大肌紧张与当前背痛或背痛发生率之间存在相关性。
