A number of recent articles have discussed the issue of laterality of chronic pain with inconclusive results. While some authors have found evidence for a preponderance of left-sided pain, others have failed to find such evidence. Unfortunately, none of the studies have clearly explained the rules used for deciding laterality. Consequently, considerable differences exist in the frequency of lateralized versus unlateralized patients in these studies, raising the question of whether variance in results reflects actual differences or different methodologies. In the current study, 101 chronic pain patients were asked to complete a drawing indicating the location and extent of their pain. These drawings were scored for the presence and absence of pain in each of 45 body areas, using a highly reliable rating system. The results suggest that laterality may be normally distributed. The findings are discussed in light of previous research, and suggestions are made for possible uses of the rating system.
最近有一些文章讨论了慢性疼痛的单侧性问题，但结果尚无定论。虽然一些作者发现了左侧疼痛占优势的证据，但另一些作者却未能找到此类证据。不幸的是，没有一项研究清楚地解释了用于确定单侧性的规则。因此，这些研究中单侧疼痛患者与非单侧疼痛患者的频率存在相当大的差异，这就引发了一个问题，即结果的差异是反映了实际差异还是不同的方法学。在当前的研究中，101名慢性疼痛患者被要求完成一幅图，表明他们疼痛的位置和程度。使用高度可靠的评分系统，对这些图中45个身体部位的每个部位是否存在疼痛进行评分。结果表明，单侧性可能呈正态分布。根据先前的研究对这些发现进行了讨论，并对评分系统的可能用途提出了建议。
