Subjects with upper abdominal pain without any demonstrable organic basis are often met with the attitude that the pain is "not real'. Twenty-five patients with long-standing upper abdominal pain but with normal findings on X-ray examination, gastroduodenoscopy, and relevant blood analyses were examined with pain-measuring techniques. Two fundamentally different techniques--pain estimate on a visual analogue scale and magnitude matching by submaximal effort tourniquet technique, respectively--gave correlating values for pain intensity (r = 0.70; P less than 0.001), indicating that these patients' asserted pain actually is "real'. Values for pain tolerance, measured with the submaximal effort tourniquet technique, were compared with pain tolerance in a group of healthy volunteers and were found to be three times lower (P less than 0.001) in the patient group. A methodological study of the submaximal effort tourniquet technique was performed on the healthy volunteers. The method was found to be suitable for use in pain studies, since the pain produced gradually increased as a linear function of time.
对于那些有上腹部疼痛但无任何明显器质性病变的患者，人们常常认为其疼痛“并非真实存在”。对25例有长期上腹部疼痛但X线检查、胃十二指肠镜检查及相关血液分析结果均正常的患者，采用疼痛测量技术进行了检查。两种截然不同的技术——分别是视觉模拟量表上的疼痛估计和次最大用力止血带技术的大小匹配——得出了相关的疼痛强度值（r = 0.70；P < 0.001），这表明这些患者声称的疼痛实际上是“真实的”。用次最大用力止血带技术测量的疼痛耐受值与一组健康志愿者的疼痛耐受值进行了比较，发现患者组的疼痛耐受值低三倍（P < 0.001）。对健康志愿者进行了次最大用力止血带技术的方法学研究。发现该方法适用于疼痛研究，因为产生的疼痛随时间呈线性函数逐渐增加。
