Also one of the more emerging techniques in rehabilitation and performance, scraping has its origins in Gua Sha, a traditional Chinese medicine technique.
Scraping acts to increase blood flow to an area by utilizing a tool or “blade” that is a blunt edge to apply the force application/treatment to the skin and underlying structures (muscle, tendon, ligament, etc.). We also notice improvements in scar tissue mobilization due to the tensile forces created on the skin.
Increasing skin mobility is incredibly important as our body relies on the sensation from our skin all movements of the joints and muscles. This sensation allows our brain to interpret and understand how the body is moving.
This is called the “brain-body map” and it is affected by pain, tension in the fascial system (tissue under the skin which links the body together structurally to bone, ligaments, muscle, skin, etc.)
