STUDY DESIGN
Case series.
PURPOSE
To determine the utility of "PainVision" apparatus for the assessment of low back pain.
OVERVIEW OF LITERATURE
A newly developed device, the PainVision PS-2100 (Nipro, Osaka, Japan), has been used to assess the perception of pain in a quantitative manner. In the current study, we aimed to evaluate the efficacy of PainVision for the assessment of low back pain.
METHODS
We assessed 89 patients with low back pain. The numeric rating scale (NRS) score, McGill Pain Questionnaire (MPQ) score and the degree of pain calculated by PainVision were measured twice at 4-week intervals in each patient. An electrode was patched on the forearm surface of the patients and the degree of pain was automatically calculated (degree of pain=100×[current producing pain comparable with low back pain-current at perception threshold/current at perception threshold]). Correlations between NRS and MPQ scores and the degree of pain were determined using Spearman's rank correlation test.
RESULTS
There was a strong correlation between the NRS and MPQ scores at each time point (rs =0.60, p<0.0001). The degree of pain also showed a moderate correlation with NRS and MPQ scores at each time point (rs =0.40, p<0.03). The change in the degree of pain over 4 weeks showed a moderate correlation with changes in the NRS and MPQ scores (rs =0.40, p<0.01).
CONCLUSIONS
PainVision as self-reported questionnaires is a useful tool to assess low back pain.
研究设计
病例系列研究。
目的
确定“疼痛视觉”设备在评估腰痛方面的效用。
文献综述
一种新开发的设备，即疼痛视觉PS - 2100（日本大阪尼普洛公司），已被用于以定量方式评估疼痛感知。在本研究中，我们旨在评估疼痛视觉在评估腰痛方面的功效。
方法
我们评估了89例腰痛患者。每位患者每隔4周测量两次数字评分量表（NRS）得分、麦吉尔疼痛问卷（MPQ）得分以及通过疼痛视觉计算出的疼痛程度。将电极贴在患者前臂表面，自动计算疼痛程度（疼痛程度 = 100×[产生与腰痛相当疼痛的电流 - 感知阈值时的电流/感知阈值时的电流]）。使用Spearman等级相关检验确定NRS和MPQ得分与疼痛程度之间的相关性。
结果
在每个时间点，NRS和MPQ得分之间存在强相关性（rs = 0.60，p < 0.0001）。疼痛程度在每个时间点与NRS和MPQ得分也显示出中度相关性（rs = 0.40，p < 0.03）。4周内疼痛程度的变化与NRS和MPQ得分的变化显示出中度相关性（rs = 0.40，p < 0.01）。
结论
疼痛视觉与自我报告问卷一样，是评估腰痛的有用工具。
