The search strategy was Guasha (OR scraping) AND pain. Risk of bias was assessed with the Cochrane criteria (i.e. sequence generation, blinding, incomplete outcome measures and allocation concealment).Five randomized controlled trials (RCTs) and two controlled clinical trials (CCTs) were included in the present study. Two RCTs compared Guasha with acupuncture in terms of effectiveness, while the other trials compared Guasha with no treatment (1 trial), acupuncture (4 trials), herbal injection (1 trial) and massage or electric current therapy (1 trial). While two RCTs suggested favorable effects of Guasha on pain reduction and response rate, the quality of these RCTs was poor. One CCT reported beneficial effects of Guasha on musculoskeletal pain but had low methodological quality.Current evidence is insufficient to show that Guasha is effective in pain management. Further RCTs are warranted and methodological quality should be improved.Guasha was defined as a therapeutic modality that uses several tools to scrape or rub the surface of the body to relieve blood (Xue) stagnation. Guasha is used for pain relief in Chinese medicine. Tools for Guasha including a Chinese soup spoon, an edge-worn coin, a slice of water-buffalo horn, a cow rib, honed jade and a simple metal cap with a smooth round lip with oil or water are used in Guasha to scrape or rub the skin to relieve blood stagnation at the body surface [1]. Guasha is also used to treat common cold, flu, respiratory problems and musculoskeletal (MS) pain [2].There are three possible mechanisms of using Guasha t %U http://www.cmjournal.org/content/5/1/5
