比较了数字评分量表和机械视觉模拟量表（M-VAS）提供实验性疼痛比率量表测量的能力。通过每种方法获得实验痛觉强度和疼痛不愉快的单独估计，以及临床疼痛的估计。口面部疼痛患者通过接触热电极对前臂施加 5 秒的有害热刺激（45-51 摄氏度），进行数字量表和 VAS 评级。这;仅在感觉 M-VAS 的情况下，推导的刺激-反应函数才适合作为幂函数。从感官 M-VAS 评级得出的幂函数预测所选择的温度是 47 摄氏度和 48 摄氏度标准温度的两倍，从而为 M-VAS 的比率尺度特性提供了证据。从感觉数值评分得出的刺激反应函数与 M-VAS 获得的刺激反应函数不同，并且不能提供对 47 摄氏度或 48 摄氏度两倍强度的温度的准确预测。与疼痛不愉快相比，M-VAS 和数值评分量表都针对疼痛感觉强度产生了可靠的不同刺激反应函数，并且两者都提供了实验和临床疼痛的一致测量 强度。最后，机械VAS 和纸笔VAS 都产生非常相似的刺激反应函数。 M-VAS 的比例尺特性与其在临床环境中易于管理和评分相结合，为研究和医疗保健环境中的简单而强大的疼痛测量技术提供了可能性。
Numerical rating scales and mechanical visual analogue scales (M-VAS) were compared for their capacity to provide ratio scale measures of experimental pain. Separate estimates of experimental pain sensation intensity and pain unpleasantness were obtained by each method, as were estimates of clinical pain. Orofacial pain patients made numerical scale and VAS ratings in response to noxious thermal stimuli (45-51 degrees C) applied for 5 sec to the forearm by a contact thermode. The; derived stimulus-response function was well fit as a power function only in the case of sensory M-VAS. The power function derived from sensory M-VAS ratings predicted temperatures chosen as twice as intense as standard temperatures of 47 degrees C and 48 degrees C, thereby providing evidence for ratio scale characteristics of M-VAS. The stimulus-response function derived from sensory numerical ratings differed from that obtained with M-VAS and did not provide accurate predictions of temperatures perceived as twice intense as 47 degrees C or 48 degrees C. Both M-VAS and numerical rating scales produced reliably different stimulus response functions for pain sensation intensity as compared to pain unpleasantness and both provided consistent measures of experimental and clinical pain intensity. Finally, both mechanical and pencil-and-paper VAS produced very similiar stimulus-response functions. The ratio scale properties of M-VAS combined with its ease of administration and scoring in clinical settings offer the possibility of a simple yet powerful pain measurement technology in both research and health care settings.
