Objective. Abdominal examination (AE) is one of the essential diagnostic methods in traditional Korean medicine that has been widely used for deciding treatment, cause, and prognosis of the disease. AE majorly depends on the experience of practitioners; therefore, standardization and quantification of AE are desperately needed. However, few studies have tried to objectify AE and established its standard. We assessed the reliability and validity of newly developed diagnostic device for AE called modified algometer (MA). Methods. Thirty-six subjects with functional dyspepsia were allocated into one of 2 groups according to gold standard of AE: epigastric discomfort without tenderness (n = 23) group or epigastric discomfort with tenderness (n = 13) group. Pressure pain threshold was evaluated at participants' epigastric region with algometer and MA. We assessed reliability and validity (sensitivity and specificity) and calculated optimal cutoff value. Results. MA showed high intertrial reliability (ICC 0.849; 0.703-0.923; P < 0.000) and validity (sensitivity: 76.92%; specificity: 60.87%), and cutoff value was 330.0 mmHg. Algometer and MA showed moderate correlation (r = 0.583, P ≤ 0.000). Conclusion. MA can be reliable and valid diagnostic device for AE and has the possibility of practical use for quantification and standardization of AE.
目的。腹部检查（AE）是传统韩医学中重要的诊断方法之一，已被广泛用于确定疾病的治疗、病因和预后。腹部检查主要依赖从业者的经验；因此，迫切需要对腹部检查进行标准化和量化。然而，很少有研究试图将腹部检查客观化并确立其标准。我们评估了一种名为改良痛觉计（MA）的新型腹部检查诊断设备的可靠性和有效性。方法。根据腹部检查的金标准，将36名功能性消化不良患者分为两组之一：无压痛的上腹部不适（n = 23）组或有压痛的上腹部不适（n = 13）组。使用痛觉计和改良痛觉计在参与者的上腹部区域评估压痛阈值。我们评估了可靠性和有效性（敏感性和特异性）并计算了最佳截断值。结果。改良痛觉计显示出较高的试验间可靠性（组内相关系数ICC 0.849；0.703 - 0.923；P < 0.000）和有效性（敏感性：76.92%；特异性：60.87%），截断值为330.0 mmHg。痛觉计和改良痛觉计显示出中度相关性（r = 0.583，P ≤ 0.000）。结论。改良痛觉计可以成为用于腹部检查的可靠且有效的诊断设备，并且有可能实际用于腹部检查的量化和标准化。
