Biomechanical tests, physical examination, spinal radiographs, a modified Minnesota Multiphasic Personality Inventory (MMPI), and a psychologic health inventory derived from the Hopkins Symptom Checklist were applied in 321 randomly selected men, ages 18-55. Each subject was evaluated for prior and current low-back pain (LBP) complaints by use of a modification of the McGill pain questionnaire. Subjects were then categorized as having no LBP (n = 106, 33%), moderate LBP (n = 144, 44.8%), and severe LBP (n = 71, 22.1%). Subjects were further subcategorized as not disabled (defined as equal or less than seven days of work lost in the previous year) and disabled (work loss greater than seven days in the prior year).
cumulative scores of the Hopkins Checklist showed that a mean score for no LBP equaled 2.5 +/- 2.9; moderate LBP was 4.3 +/- 3.2; and severe LBP was 4.6 +/- 3 (p = .0000). The disabled group was significantly different on both MMPI and Hopkins Checklist. The 20 disabled subjects had significant elevations of hypochondriasis (p = .0006) and hysteria (p = .005) when compared with nondisabled subjects with LBP. The mean score for disabled subjects on the Hopkins Checklist was 7.35 +/- 4.49, while the score was 4.17 +/- 3.15 (p = .0001) for the nondisabled subjects with LBP. In the general male population, patients with disabling LBP conditions form a distinctive subgroup comparable to those patients seen in selected LBP clinics.
对321名年龄在18至55岁之间随机选取的男性进行了生物力学测试、体格检查、脊柱X光片、改良的明尼苏达多相人格调查表（MMPI）以及源自霍普金斯症状清单的心理健康量表评估。通过对麦吉尔疼痛问卷进行修改，对每位受试者既往和当前的下背痛（LBP）主诉进行评估。然后将受试者分为无LBP组（n = 106，33%）、中度LBP组（n = 144，44.8%）和重度LBP组（n = 71，22.1%）。受试者进一步细分为未致残组（定义为上一年工作损失等于或少于7天）和致残组（上一年工作损失超过7天）。
霍普金斯量表的累积得分显示，无LBP组的平均得分为2.5±2.9；中度LBP组为4.3±3.2；重度LBP组为4.6±3（p = 0.0000）。致残组在MMPI和霍普金斯量表上均有显著差异。与未致残的LBP受试者相比，20名致残受试者的疑病症（p = 0.0006）和癔症（p = 0.005）得分显著升高。致残受试者在霍普金斯量表上的平均得分为7.35±4.49，而未致残的LBP受试者的得分为4.17±3.15（p = 0.0001）。在一般男性人群中，致残性LBP患者形成了一个独特的亚组，与在特定LBP诊所所见的患者相当。
