This study aims to compare nail-fold capillary blood velocity (CBV) according to the presence or absence of cold hypersensitivity in the hands (CHH) using nail-fold capillaroscopy under cold stress conditions. Eleven participants were taken from the cohort study for observing long-term health status of the faculty of Semyung university. Seven of the participants displayed CHH while four showed signs of non-CHH. CBV between 0 and 60 seconds (S1) and between 240 and 300 seconds (S2) was measured under cold stress for 5 minutes, respectively, and the average value was used to compare non-CHH group and CHH group. Body mass index, Nogung (PC8) temperature and temperature difference between Nogung (PC8) and Hyeopbaek (LU4) were significantly lower in CHH group compared to non-CHH group. The S2-S1 CBV difference was negatively correlated with PC8 temperature and PC8-LU4 temperature, and positively correlated with cold pattern score and cold hypersensitivity visual analog scale. The CHH group had a lower CBV overall than non-CHH group, and the S2-S1 CBV difference was significantly higher in the CHH group than in non-CHH group. This study suggests that CBV measured by nail-fold capillarosopy might be a useful indicator of cold hypersensitivity properties.
