It is very difficult to assess pain intensity. A method for quantitative measurement of pain intensity using a painless electrical stimulation (PainVision PS-2100; Nipro Co, Osaka, Japan) has recently been developed in Japan. Pain degree is calculated from two parameters, current perception threshold and pain compatible electrical current by using PainVision. The former parameter is defined by the lowest electrical current detected; the latter parameter defined by the electrical current judged as being compatible with the intensity of ongoing pain. The pain degree calculated by PainVision showed a significant positive correlation with the pain intensity assessed by visual analogue scale, though there were inter-individual differences in the measured values. It is likely that PainVision is an appropriate device to quantify pain intensity for intra-individual comparison between before and after management of pain.
评估疼痛强度非常困难。日本最近开发了一种使用无痛电刺激（PainVision PS - 2100；日本大阪日医工株式会社）定量测量疼痛强度的方法。疼痛程度由两个参数计算得出，即电流感知阈值和通过PainVision得出的疼痛适配电流。前一个参数由检测到的最低电流定义；后一个参数由判断为与持续疼痛强度相适配的电流定义。尽管测量值存在个体差异，但通过PainVision计算出的疼痛程度与通过视觉模拟量表评估的疼痛强度呈显著正相关。PainVision很可能是一种适用于量化疼痛强度以进行疼痛管理前后个体内比较的设备。
