Background summary
Chronic pain is a highly prevalent condition, with approximately 1 in 5 suffering from it in Europe. It has a large impact on the quality of life, but also increases costs of global health care and absenteeism at work. A wide spread increased sensitivity of the central nervous system to noxious stimulation plays a major role in the development and maintenance of chronic pain, and can be observed as a decreased pain threshold for electrocutaneous stimulation. Although many clinical studies have demonstrated decreased electrical pain thresholds (EPTs) in groups of chronic pain patients, the measurement variability is still substantial due to the use of non-optimal stimulation electrodes. The presently used electrodes cause a deep and non-selective activation of both pain and non-pain related nerve fibers, which hampers the patient in determining the pain threshold. Therefore, the CutaStim electrode has been designed with improved selectivity towards pain related nerve fibers in the superficial skin. We hypothesize that the CutaStim electrode has a higher measurement reliability.
Study objective
It is hypothesized that the CutaStim electrode will have a higher one week test-retest reliability than the currently used electrodes.
Study design
EPT and NRS at both visits (W0 and W1); CSI, CSQ and PD-Q only at first visit (W0)
