Pain drawings were obtained from a group of 651 patients who had chronic low-back pain. Pain drawings were rated in four grades according to the degree of organic and nonorganic pain. Experienced and inexperienced evaluators were used. The reliability was excellent with an interevaluator reliability between 73% and 78%. A correlation between pain drawings and Waddell's nonorganic physical signs demonstrated that a large proportion of patients with high Waddell scores had nonorganic pain drawings. No significant differences were noted in the distribution of Waddell scores and pain drawings based on patient gender or payment status (i.e., medicolegal or workers' compensation). Pain drawings afford an important adjunct in the physician's assessment of chronic low-back pain.
从一组651名患有慢性下背痛的患者那里获取了疼痛图。根据器质性和非器质性疼痛的程度，将疼痛图分为四个等级。使用了有经验和无经验的评估者。评估者间信度在73%至78%之间，信度极佳。疼痛图与瓦德尔非器质性体征之间的相关性表明，瓦德尔评分高的患者中很大一部分有非器质性疼痛图。基于患者性别或付费状态（即法医或工伤赔偿），在瓦德尔评分和疼痛图的分布上未发现显著差异。疼痛图为医生评估慢性下背痛提供了一项重要辅助手段。
