The reproducibility of measurements with the triaxial lumbar dynamometer Isostation B-200 was measured in 61 volunteers with or without low back problems. Both for the intra- and interrater measurements the reproducibility was good (r = 0.76-0.89) for lateral flexions and almost as good (r = 0.76-0.87) for the sum of all ranges of motion (SROM). The corresponding reproducibilities were excellent (r = 0.82-0.99) for the isometric strength and good (r = 0.60-0.90) for isoinertial flexion-extension repetition test parameters in the main (primary axis) direction. A number of parameters were combined into three functional indices: the reproducibility for "power" and "work" index was good (r = 0.76-0.94) in both intra- and interrater conditions, whereas for "movement" index it was somewhat weaker (r = 0.53-0.87). It is concluded that parameters: lateral flexions, SROM, isometric strength, and functional indices (power and work) are reproducible enough to use in further studies.
在61名有或没有下背部问题的志愿者中，对三轴腰椎测力计Isostation B - 200测量的可重复性进行了测定。对于评估者内和评估者间的测量，侧弯的可重复性良好（r = 0.76 - 0.89），所有运动范围总和（SROM）的可重复性也几乎同样良好（r = 0.76 - 0.87）。等长力量的相应可重复性极佳（r = 0.82 - 0.99），在主要（主轴）方向上的等惯性屈伸重复测试参数的可重复性良好（r = 0.60 - 0.90）。一些参数被组合成三个功能指标：“功率”和“功”指标在评估者内和评估者间条件下的可重复性均良好（r = 0.76 - 0.94），而“运动”指标的可重复性稍弱（r = 0.53 - 0.87）。得出的结论是：侧弯、SROM、等长力量和功能指标（功率和功）等参数的可重复性足以用于进一步的研究。
