背景疼痛绘图（PD）是评估疼痛患者的重要组成部分。这项工作的目的是提出一种新的方法来量化疼痛的程度和位置的重测信度。此外，PD变量和慢性颈痛（CNP）和慢性腰痛（CLBP）患者的临床特征之间的关联进行了explored.MethodsFifty-one患者与CLBP和56例CNP参与。每名患者使用数字平板电脑对两个连续的PD进行阴影处理。开发了软件来量化疼痛程度，分析PD之间的疼痛重叠并生成疼痛频率图。疼痛程度和临床特征，包括疼痛强度，残疾，心理困扰和认知function.ResultsThe水平之间的相关性，CLBP和CNP疼痛程度的组内相关系数非常高：0.97（95%CI：0.95-0.98）和0.92（95%CI：0.87-0.98），分别。Bland Altman显示平均差异接近于零：CNP组为5.4%像素，CLBP组为3%像素。CLBP和CNP的疼痛程度和疼痛强度之间以及CNP的疼痛程度和残疾之间存在显著相关性。疼痛程度和水平的困扰或认知function.ConclusionsA新的方法收购PD之间没有关系。报告疼痛程度和疼痛部位的重测信度在CNP和CLBP患者中得到支持。未来的研究需要建立PD的心理测量学特性。
BackgroundPain drawings (PDs) are an important component of the assessment of a patient with pain. The aim of this work is to present the test-retest reliability of a novel method of quantifying the extent and location of pain. Additionally, the association between PD variables and clinical features in patients with chronic neck pain (CNP) and chronic low back pain (CLBP) was explored.MethodsFifty-one patients with CLBP and 56 patients with CNP participated. Each patient shaded two consecutive PDs using a digital tablet. Software was developed to quantify the pain extent, to analyse the pain overlap between PDs and to produce pain frequency maps. Correlations were obtained between pain extent and clinical features including the level of pain intensity, disability, and psychological distress and cognitive function.ResultsThe intraclass correlation coefficients for pain extent in CLBP and CNP were very high: 0.97 (95% CI: 0.95-0.98) and 0.92 (95% CI: 0.87-0.98), respectively. The Bland Altman showed a mean difference close to zero: 5.4% pixels in CNP group and 3% pixels in the CLBP group. Significant correlations were observed between pain extent and pain intensity in CLBP and CNP and pain extent and disability in CNP. There was no relation between pain extent and the level of distress or cognitive function.ConclusionsA novel method for the acquisition of PD was presented. Test-retest reliability of reporting pain extent and pain location was supported in people with CNP and CLBP. Future research is needed to establish psychometric properties of PD.
