Graston technique, Scraping and Instrument assisted soft tissue mobilization, or more commonly known as IASTM, are the use of tools to assess tissue quality and to treat areas identified to have scar tissue, soft tissue restrictions, chronic inflammation or degeneration. The IASTM used today was derived from the Cyriax cross-friction massage developed by Dr. James Cyriax, better known as the father of orthopedic medicine. He was a British orthopedic surgeon whose work has had great influence in the fields of sports medicine and physical therapy. There are many different versions of IASTM out there these days. Tools are typically made of stainless steel or hard plastic and designed to contour the shape of the body. The therapist applies firm pressure to the tool as the tool glides across the tissue in a scrapping fashion. A lubricant of some sort, typically lotion, is used to allow the tools to glide across the skin more freely. The instruments work to comb through soft tissue restrictions and scar tissue, producing microtrauma to the affected tissue. This stimulates a local inflammatory process, initiating reabsorption of unhealthy tissue and promoting tissue remodeling and healthy tissue production. Soft tissue restrictions can occur following surgery. These restrictions can also develop from overuse, such as running, throwing, repeated motions at work, or even prolonged postures sitting at a desk. Likewise, they can develop with lack of use, as may be the case with prolonged splinting or bracing. Research supports the idea that IASTM may have an impact on physiological changes by providing an increase in blood flow, reduction in tissue viscosity, myofascial release, interruption of pain receptors, and improvement of flexibility of underlying tissue. It is suggested that IASTM is an effective treatment intervention for reducing pain and improving function in less than a three-month period.
