Objective.We aim to study the therapeutic effects of scraping by investigating the changes of temperature and local blood perfusion
volume in healthy subjects after scraping stimulation, and to explore the mechanism of scraping stimulation from the points of
microcirculation and energymetabolism. Methods. Twenty-three health subjects were included in this study. Local blood perfusion
volume and body surface temperature was detected at 5min before scraping stimulation, 0, 15, 30, 60 and 90min after scraping
using Laser Doppler imager and infrared thermograph. Results. Significant increase was noted in the blood perfusion volume in the
scraping area within 90 minutes compared to the baseline level and non-scraping area (P < 0.001). Compared with non-scraping
area, an increase of body temperature with an average of 1◦C was observed after scraping stimulation (P < 0.01). Conclusion.
Scraping can significantly improve the blood perfusion volume and increase the temperature in the scraping area, promoting the
local blood circulation and energy metabolism.
