RESUMEN
Objective:To observe the characteristics of back scraping skin symptoms in sub-health people through diagnostic scraping, and explore the characteristics of back scraping skin symptoms in sub-health people with different constitutions.Methods:By adopting a cross-sectional study method, the Third Affiliated Hospital of Guangzhou University of Traditional Chinese Medicine recruited volunteers through a combination of offline and online methods from March 2021 to September 2022. Totally 2 239 sub-health people were treated for TCM constitution identification and were diagnostic scraped with Wentong scraping cup. The differences of back scraping skin symptoms in the color, speed, amount, shape, nature of pain and feeling characteristics under scraping board were compared between sub-health people with different TCM constitutions and gentle constitution.Results:There were differences in the characteristics of Sha Xiang among sub-health individuals with different constitutions. Among them, 49.02% (351/716) of individuals with a gentle constitution had a bright red color, 90.64% (649/716) had a fast rate of appearance, 5.73% (41/716) had a large amount of sha, 3.35% (24/716) had a patchy shape, 3.35% (24/716) felt a stabbing pain, and 0 felt nodules under the scraping plate. Among individuals with a damp-heat constitution, 86.72% (457/527) had a bright red color, 95.64% (504/527) had a fast rate of appearance, 100.00% (527/527) had a large amount of sha, 88.80% (468/527) had a patchy shape, 95.64% (504/527) felt a stabbing pain and 97.72% (515/527) felt nodules under the scraping plate. There was a statistically significant difference between the two groups ( χ2 values were 11.27 to 1 243.00, all P<0.05). Conclusions:The characteristics of back scraping skin symptoms of sub-health people with different constitutions are different. It is expected that the type of TCM constitution of sub-health people can be judged according to the characteristics of scraping skin symptoms in the future, in order to guide patients in health management and improve their satisfaction with traditional Chinese medicine scraping treatment.
