Scraping therapy (Gua-Sha) is the stretching of the fascia using a very thin, blunt blade. This therapy is most commonly used around the joints and across surfacable muscle areas (such as the shins and scapulas).
The use of scraping was originally used in ancient China and in ancient Chinese, Gua-Sha means the break up of fascia. Here, we treat fascia by stretching it as modern research shows we can’t physically break fascial tissues without surgery.
The Chinese method is therefore adapted and the tool of a thin, blunt blade is still used.
