title: [PainVision].
abstract: 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.
