目的：检验诱发疼痛模型(站立模型)的有效性。材料和方法：最初，腰痛(LBP)患者在身体疼痛图上报告其典型症状的性质和位置。然后，LBP患者和背部健康的人站2个小时，报告基线和每15分钟症状的强度、质量和位置。将LBP患者的典型症状的性质和部位与站立时的症状进行比较。背部健康的人被分为疼痛开发者(PD)和非疼痛开发者(PD)。结果：两组患者的典型症状和站立时症状的性质和部位无显著差异(P>；0.05)。30%的LBP患者使用三个症状描述符来描述典型症状。只有2名LBP患者使用这些描述符来描述典型症状，但不是在站立时。LBP患者和PDS患者在站立状态中报告的症状的性质和部位没有差异(P>；0.05)。30%的LBP患者在站立时使用了四个症状描述符。PD报告的症状没有LBP患者没有报告的症状。讨论：这项研究提供了证据，表明站立范式中经历的症状与LBP患者经历的症状相似，从而支持了该范式的有效性。
Objectives:Examine the validity of an induced pain paradigm in which people stand while performing simulated light work tasks (standing paradigm).Materials and Methods:Initially, people with low back pain (LBP) reported the quality and location of their typical symptoms on a body pain diagram. Then, people with LBP and back-healthy people stood for 2 hours and reported the intensity, quality, and location of symptoms at baseline and every 15 minutes. Quality and location of typical symptoms of people with LBP were compared with their symptoms during standing. Back-healthy people were separated into pain developers (PDs) and nonpain developers. Symptom quality and location were compared between people with LBP and PDs.Results:There were no differences in the quality and location of typical symptoms and symptoms during standing in people with LBP (P> 0.05). Three symptom descriptors were used by> 30% of people with LBP to describe typical symptoms. Only 2 people with LBP used these descriptors to describe typical symptoms but not during standing. There were no differences in the quality and location of symptoms reported in standing between people with LBP and PDs (P> 0.05). Four symptom descriptors were used by> 30% of participants with LBP during standing. There were no symptoms reported by PDs that were not reported by people with LBP.Discussion:This study provides evidence that symptoms experienced during the standing paradigm are similar to symptoms experienced by people with LBP and, thus, provides support for the validity of the paradigm.
