Verbal pain description and assessment of functional limitations are key components in the clinical evaluation of patients with low back pain syndromes. Using the McGill Pain Questionnaire (MPQ) to quantify the pain experience and the Oswestry Disability Questionnaire (ODQ) to quantify functional disability, a study was undertaken to determine the efficiency with which the MPQ and ODQ were capable of enhancing the differential diagnosis of three broad categories of low back syndromes. Three discriminative models were employed. The combined discriminant model (MPQ/ODQ) yielded the highest accuracy, 0.90, and it was the only model with acceptable predictive power. The greatest utility of the discriminant models was found to be ruling out nonspecific low back pain and ruling in radiculopathy, with and without neurological deficits. Subjective pain and disability appear to have the potential for successfully differentiating broad categories of low back pain. Further studies need to be performed to assess the discriminant power of the MPQ and ODQ for specific diagnostic entities.
疼痛的言语描述以及功能受限评估是腰痛综合征患者临床评估的关键组成部分。一项研究采用麦吉尔疼痛问卷（MPQ）来量化疼痛体验，采用奥斯威斯利残疾问卷（ODQ）来量化功能残疾，以确定MPQ和ODQ在增强对三大类腰痛综合征鉴别诊断方面的有效性。采用了三种判别模型。联合判别模型（MPQ/ODQ）的准确率最高，为0.90，且是唯一具有可接受预测能力的模型。判别模型的最大作用在于排除非特异性腰痛以及诊断神经根病，无论有无神经功能缺损。主观疼痛和残疾似乎有可能成功区分不同大类的腰痛。需要开展进一步研究来评估MPQ和ODQ对特定诊断实体的判别能力。
