A set of measurements for the quantification of low back pain was tested on 48 subjects suffering from idiopathic low back pain. Measurements were performed according to a repeated latin square model. Carry-over effects were found to be insignificant. Inter- and Intraobserver errors were small in proportion to the contribution of the subjects to the total variance of the variables indicating a good objectivity and repeatability of the test. Calculation of sum scores from similar questions, e.g. total pain score from six pain variables, permitted a further reduction of experimental errors.
对48名患有特发性腰痛的受试者进行了一组用于量化腰痛的测量。测量按照重复拉丁方模型进行。发现残留效应不显著。观察者间和观察者内误差与受试者对变量总方差的贡献相比很小，表明该测试具有良好的客观性和可重复性。从相似问题计算总分，例如从六个疼痛变量计算总疼痛评分，可进一步减少实验误差。
