Chronic pain patients (101) were assigned ratings of impairment and disability and were assessed for organic pathology and pain behavior through comprehensive testing procedures. As predicted, higher ratings of impairment and disability were significantly associated with higher levels of both physical pathology and pain behaviors. These results indicate that conditioning and pathologic processes significantly influence impairment and disability ratings. Many patients showed higher disability than impairment ratings, which suggests the possibility of gainful employment in less demanding jobs. However, the current disability system rewards sickness and dysfunction and discourages patients from resuming work.
慢性疼痛患者（101名）被评定了损伤和残疾等级，并通过全面的测试程序对其器质性病变和疼痛行为进行了评估。正如所预测的那样，更高的损伤和残疾等级与更高水平的身体病变和疼痛行为显著相关。这些结果表明，条件作用和病理过程对损伤和残疾等级有显著影响。许多患者的残疾等级高于损伤等级，这表明他们有可能从事要求较低的有酬工作。然而，当前的残疾制度奖励疾病和功能障碍，阻碍患者恢复工作。
