受试者（29）使用感官强度的量化语言描述符（即，弱的，温和的，强烈的）或不愉快（即，恼人的、不愉快的、令人痛苦的），以评估在宽刺激范围内由牙髓的疼痛电刺激引起的感觉的强度或不愉快，以及由施加到暴露的牙质的天然热牙髓刺激、冷喷雾引起的感觉的强度或不愉快。受试者匹配的强度或不愉快的感觉诱发的自然刺激的电刺激的方法的限制和方法的恒定刺激。量化的口头描述符值的感觉强度或不愉快的电刺激线性相关的刺激强度的对数尺度，表明可以描述的关系的幂函数。自然热刺激的量化语言描述和与热刺激直接匹配的电刺激强度确定了临床刺激数据点的坐标。这一点接近实验刺激功率函数，表明临床刺激的言语幅度是由与临床刺激相匹配的特定电刺激强度的言语幅度预测的。这种一致性支持使用量化的语言描述符评估实验控制的伤害性刺激和不受控制的临床疼痛感觉的有效性。它也支持临床和实验疼痛感觉与这些感觉的不愉快之间的直接匹配的有效性。该程序为临床疼痛评估提供了一个有用的独立验证范式。
Subjects (29) used quantified verbal descriptors of sensory intensity (i.e., weak, mild, intense) or unpleasantness (i.e., annoying, unpleasant, distressing) to assess the intensity or unpleasantness of sensations evoked by painful electrical stimulation of the tooth pulp over a broad stimulus range, and by a natural thermal tooth pulp stimulus, cold spray applied to exposed dentin. Subjects matched the intensity or unpleasantness of the sensations evoked by the natural stimulus to that of the electrical stimuli by both the Method of Limits and the Method of Constant Stimuli. Quantified verbal descriptor values of either the sensory intensity or unpleasantness of the electrical stimuli were linearly related to stimulus intensity on a log scale, indicating that the relationships can be described by power functions. The quantified verbal description of the natural thermal stimulus and the intensity of the electrical stimulus directly matched to the thermal stimulus determined the coordinates of the clinical stimulus data point. This point was close to the experimental stimulus power function, indicating that the verbal magnitude of the clinical stimulus is predicted by the verbal magnitude of the specific electrical stimulus intensity that was matched to the clinical stimulus. This consistency supports the validity of the use of quantified verbal descriptors for the assessment of both experimentally controlled noxious stimulation and uncontrolled clinical pain sensations. It also supports the validity of direct matches between clinical and experimental pain sensations and the unpleasantness of these sensations. This procedure provedes a useful independent validational paradigm for clinical pain assessment.
