We present a newly developed continuous pain score meter (CPSM). The CPSM is based on the principles of the visual analog score (VAS), and electronically measures pain score in a continuous, instead of a single, manner. In this study, we determine the test-retest reliability of this meter. ⋯ ICC of peak CPS (0.89 and 0.83) and AUC CPS (0.79 and 0.86) for nail and arm showed a good reproducibility. This study has successfully established the test-retest reliability of the CPSM. The real-time continuous pain measurement may provide more detailed information on a subjects' pain perception compared to a single VAS, in particular during an interval of pain stimuli.

The mechanisms underlying complex regional pain syndrome (CRPS) have been increasingly studied over the past decade. Classically, this painful and disabling disorder was considered to emerge from pathology of the central nervous system. However, the involvement of additional peripheral disease mechanisms is likely, and recently these mechanisms have also attracted scientific attention. ⋯ Additionally, currently known risk factors for CRPS will be addressed. Insight into risk factors is of relevance as it facilitates early diagnosis and tailored treatment. Moreover, it may provide clues for further unraveling of the pathogenesis and etiology of CRPS.
