The submaximal effort tourniquet test has been widely used to evaluate experimental and chronic pain; however, there has been great variation in the manner in which the test has been applied. The present study systemitically evaluates how different levels of exercise duration and effort affect subjects' report of pain. The data indicate the following: (1) the manner in which the exercise is performed has an important effect on subjects' rating of pain, and (2) under all conditions studied, the pain ratings do not increase as a linear function of time. Both findings warrant precautions when using the submaximal effort tourniquet test to study experimental and chronic pain.
次最大用力止血带试验已被广泛用于评估实验性疼痛和慢性疼痛；然而，该试验的应用方式存在很大差异。本研究系统地评估了不同运动持续时间和用力水平如何影响受试者的疼痛报告。数据表明：（1）运动的执行方式对受试者的疼痛评分有重要影响；（2）在所研究的所有条件下，疼痛评分并非随时间呈线性增加。这两个发现都表明在使用次最大用力止血带试验研究实验性疼痛和慢性疼痛时需要谨慎。
