Twenty subjects (6 male, 14 female) with low back pain were examined by two experienced and licensed chiropractic doctors (E1 and E2). Both examiners examined the patients using a Toftness Electromagnetic Radiation Receiver (EMRR) and by manual palpation (MP) of the spinous processes. Interexaminer reliability was calculated at three sites (L3, L4, L5) for the following combinations: a) E1,MP--E2,MP; b) E1,EMRR--E2,EMRR; c) E1,MP--E2,EMRR; and) d) E2,MP--E1,EMRR, and intraexaminer reliability was calculated for the following variables: e) E1,MP--E1,EMRR; and f) E2,MP--E2,EMRR. Results of a Kappa coefficient analysis for interexaminer reliability of the stated combinations and at the specific sites were: a) -0.071, 0.400, 0.200; b) -0.013, 0.100, -0.120; c) 0.286, 0.300, 0.200; d) -0.081, 0.000, 0.048. These results predominantly indicate a poor to fair interexaminer reliability. The results of a Kappa coefficient analysis for intraexaminer reliability of the stated combinations were: e) 0.111, 0.400, 0.737; f) 0.000, 0.100, 0.368. These results indicate a poor to fair reliability. It was concluded that in subjects with low back pain the EMRR may not be a reliable indicator of spinal joint dysfunction.
20名患有腰痛的受试者（6名男性，14名女性）由两名经验丰富且持有执照的脊椎按摩师（E1和E2）进行检查。两位检查者使用托夫尼斯电磁辐射接收器（EMRR）并通过手动触诊（MP）棘突对患者进行检查。计算了以下组合在三个部位（L3、L4、L5）的检查者间可靠性：a）E1，MP - E2，MP；b）E1，EMRR - E2，EMRR；c）E1，MP - E2，EMRR；d）E2，MP - E1，EMRR，并计算了以下变量的检查者内可靠性：e）E1，MP - E1，EMRR；f）E2，MP - E2，EMRR。所述组合在特定部位的检查者间可靠性的Kappa系数分析结果为：a）-0.071、0.400、0.200；b）-0.013、0.100、-0.120；c）0.286、0.300、0.200；d）-0.081、0.000、0.048。这些结果主要表明检查者间可靠性较差至一般。所述组合的检查者内可靠性的Kappa系数分析结果为：e）0.111、0.400、0.737；f）0.000、0.100、0.368。这些结果表明可靠性较差至一般。得出的结论是，在患有腰痛的受试者中，EMRR可能不是脊柱关节功能障碍的可靠指标。
