Instrument Assisted Soft Tissue Mobilisation (IASTM) is a technique that enables therapists to efficiently locate and treat soft tissue dysfunction.

The technique itself is said to be a modern evolution from Traditional Chinese Medicine called Gua Sha. However, Gua Sha was not used in treating Musculoskeletal conditions but was traditionally applied along meridians to move the bad chi out through the skin. IASTM is a procedure that is rapidly growing in popularity due to its effectiveness and efficiency while remaining non-invasive.
