A considerable number of instruments have been described for noninvasive measurements of the sagittal configuration and mobility of the thoracolumbar spine. With Debrunner's kyphometer, it is possible to obtain this information in approximately 1 minute in a clinical setting. A minor modification of the kyphometer to increase its range of measurement of lumbar extension is described. Repeatability of measurements with the instrument was studied on 31 healthy individuals in a randomized cross-over model. In another study, ten individuals were examined ten times each by the same investigator within 3 weeks. These studies showed good reproducibility for measurements with the kyphometer. The importance of standardized instructions for measurement procedures is emphasized. The statistical approach to repeatability of measurements is discussed.
已经描述了许多用于非侵入性测量胸腰椎矢状位形态和活动度的仪器。使用德布勒纳后凸测量仪，在临床环境中大约1分钟就可以获得这些信息。本文描述了对后凸测量仪进行的微小改进，以增加其腰椎伸展测量范围。在随机交叉模型中，对31名健康个体使用该仪器测量的重复性进行了研究。在另一项研究中，同一名研究者在3周内对10名个体每人检查了10次。这些研究表明，使用后凸测量仪进行测量具有良好的可重复性。强调了测量程序标准化说明的重要性。讨论了测量重复性的统计方法。
