疼痛信息的传递需要患者编码和传递疼痛信息，观察者解码和解释疼痛信息。Rosenthal（1982）的疼痛信息传递模型被用于分析面部表情在疼痛信息传递中的作用。肩痛患者进行一系列肩关节运动的录像带被展示给一组5名法官。观察员和患者提供了相同的口头描述量表的患者疼痛的评级。分析了患者的疼痛报告，观察者对患者疼痛的判断和基于面部动作编码系统的患者面部表情测量之间的关系。结果表明，虽然观察者可以粗略区分患者的疼痛状态，但他们（1）不是特别敏感，（2）可能会系统地降低患者的痛苦强度。此外，观察者似乎没有充分利用患者面部表情中的信息。疼痛患者的研究结果和培训的卫生保健工作者的影响进行了讨论，为今后的研究方向。
The communication of pain requires a sufferer to encode and transmit the experience and an observer to decode and interpret it. Rosenthal's (1982) model of communication was applied to an analysis of the role of facial expression in the transmission of pain information. Videotapes of patients with shoulder pain undergoing a series of movements of the shoulder were shown to a group of 5 judges. Observers and patients provided ratings of the patients' pain on the same verbal descriptor scales. Analyses addressed relationships among patients' pain reports, observers' judgements of patients' pain and measures of patients' facial expressions based on the Facial Action Coding System. The results indicated that although observers can make coarse distinctions among patients' pain states, they (1) are not especially sensitive, and (2) are likely to systematically downgrade the intensity of patients' suffering. Moreover, observers appear to make insufficient use of information that is available in patients' facial expression. Implications of the findings for pain patients and for training of health-care workers are discussed as are directions for future research.
