Graston Technique falls under the scope of "instrument assisted soft tissue mobilization". This means it is a form of therapy that uses specialized stainless steel instruments in order to achieve results. These instruments help your practitioner to assess and treat tissue that is causing you pain, and to treat and mobilize chronically tight tissues, scar tissue, tendons and fascia.
The instruments themselves have two main purposes: to help "break down" abnormal densities in tissue (es: scar tissue) and to re-initiate first-stage healing in the body. When we sustain an injury, the body sends healing substances via the blood stream to help healing; white blood cells help to clear out debris, and connective tissue cells help to lay down new collagen for tissue rebuilding. These connective tissue cells help to build scar tissue which then acts as a band aid to help repair the injured tissue. However, after time and without proper rehabilitation and treatment, this can build up and lead to decreased motion, flexibility and pain. The therapy of Graston acts as a mild injury to the tissue, which allows the healing process to start over again, allowing for proper healing, decreased pain, and increased range of motion.
