Abstract

Eleven chronic low back pain (CLBP) and 11 age- and sex-matched control subjects were tested during two separate sessions for the perception of radiant heat and uncomfortably loud tones. Following the determination of a subject's pain threshold (PT) for radiant heat, a standard signal detection methodology was used to present 26 trials each of 4 stimulus levels. The stimuli were rated on a 9-point scale ranging from 'nothing' to 'very strong pain.' A similar procedure was used for the tone stimuli with the 9-point scale ranging from 'nothing' to 'very strongly uncomfortable.' It was found that the CLBP group had both higher heat pain and tone discomfort thresholds than the control group. For radiant heat only, the CLBP group had poorer discrimination as determined by P(I). The results are discussed within the framework of the hypervigilance and adaptation theories of pain perception.

摘要

在两个不同的时间段对11名慢性下腰痛（CLBP）患者和11名年龄及性别匹配的对照受试者进行了辐射热感知和极度响亮音调不适的测试。在确定受试者的辐射热疼痛阈值（PT）后，采用标准信号检测方法，对4种刺激水平各进行26次试验。刺激按照从“无”到“非常剧烈疼痛”的9分制进行评分。对音调刺激采用类似程序，9分制范围从“无”到“非常强烈不适”。结果发现，CLBP组的热痛阈值和音调不适阈值均高于对照组。仅对于辐射热，根据P(I)确定CLBP组的辨别能力较差。在疼痛感知的过度警觉和适应理论框架内对结果进行了讨论。
