IASTM stands for Instrument-Assisted Soft Tissue Massage. IASTM is a process in which the Physical or Occupational Therapist uses a set of hand held instruments to break down the scar tissue and fascial restrictions in soft tissues (muscles, ligaments, tendons, fascia, and nerves). This technique also includes Graston technique and cupping.
The tools are used to find and treat the restricted areas by causing controlled microtrauma. This will stimulate a local inflammatory response, which initiates reabsorption of excessive scar tissue and facilitates the body's natural healing process. Adhesions within the soft tissue that may have developed because of surgery, immobilization, or repetitive strain, are broken down, allowing the patient to regain function and decrease pain.
