The submaximum effort tourniquet technique (SETT) is becoming more widely used as part of the clinical assessment of chronic pain patients despite little information about the scaling of this technique. Ratio scaling procedures resulted in a linear function, presumed to underlie clinical application of the SETT, for only 11% of the subjects. Therefore, current clinical use of the tourniquet ratio score should be questioned. Normals also obtained significantly more negatively accelerated power functions than pain patients with no difference in tolerances. Differences in these growth curves are discussed with reference to the concept of pain endurance. Continued needs for standardized pain evaluation techniques suggest that this type of psychophysical scaling procedure may improve the precision of some clinical pain assessments.
尽管关于次最大用力止血带技术（SETT）的量表化信息很少，但它作为慢性疼痛患者临床评估的一部分正被越来越广泛地使用。比率量表程序仅在11%的受试者中产生了线性函数，而该线性函数被认为是SETT临床应用的基础。因此，目前止血带比率评分的临床应用值得质疑。正常人也比疼痛患者获得了明显更多的负加速幂函数，且耐受性没有差异。本文参照疼痛耐力的概念讨论了这些生长曲线的差异。对标准化疼痛评估技术的持续需求表明，这种心理物理学量表程序可能会提高一些临床疼痛评估的精确度。
