From a sample of 958 individuals, a group with no anamnestic recall of notable low back trouble (n=510) was selected to provide reference values for lumbar sagittal mobility. The measurement technique employed a flexicurve to give angular measures for maximal sagittal mobility in upper (T12-L4) and lower (L4-S2) regions. The results are presented in the form of reference ranges and modal values, stratified by age and sex. A wide variation in the 'normal' range of mobility at all ages is confirmed. Males had higher values for flexion, whilst females showed higher values for extension and for mobility in the lower region. Sagittal mobility declined with age at different rates in males and females for both flexion/extension and upper/lower measures. Generally speaking, mobility was reduced by some 50% in old age compared with childhood, the reduction being most marked for measures of flexion and upper lumbar mobility.
从958名个体的样本中，选取了一组没有明显腰痛既往史的个体（n = 510），以提供腰椎矢状面活动度的参考值。测量技术采用了弯曲测量仪，以给出上（T12 - L4）和下（L4 - S2）区域最大矢状面活动度的角度测量值。结果以参考范围和众数的形式呈现，并按年龄和性别分层。证实了各年龄段“正常”活动度范围存在很大差异。男性在屈曲方面的值较高，而女性在伸展以及下区域活动度方面的值较高。男性和女性在屈曲/伸展以及上/下测量方面，矢状面活动度随年龄下降的速率不同。一般来说，与儿童时期相比，老年时活动度降低了约50%，屈曲和上腰椎活动度测量值的降低最为明显。
