What is IASTM?
IASTM stems from the theory of Friction Massage first introduced in the early 1900s by James Cyriax – known as the Father of Orthopedic Medicine. The efficacy of the friction massage treatment is proven to mitigate the adverse effects of the lack of movement during the healing process. Lack of movement during connective tissue repair can lead to unhealthy scar formation, increased pain when it is again moved and thus, scar stretching. This tissue repair process is when the scar is healing and forming which involves specialized cells, called fibroblasts, to produce a fibrous connective tissue made up of collagen.
Lack of or no movement during the healing process can throw off the connection and balance of the collagen-rich tissue and can increase the number and thickness of collagen fibers. Other negative effects are an increase in the intermolecular cross-links and a decrease in the water content of the extracellular matrix. All of which lead to increased scar formation. 1
