Your physical therapist may decide to use an instrument assisted soft tissue mobilization during hands on therapy to effectively break down fascial restrictions and scar tissue. The design of these specific instruments provides the therapist with the ability to locate restrictions and to treat the affected area with the appropriate amount of pressure.
The Instrument Assisted Soft Tissue Mobilization (IASTM) tool is used to break down scar tissue or fascial restrictions. The IASTM tool helps to break down not only scar tissue but also release fascial restrictions by means of controlled microtrauma. What this means is the use of the tool will actually irritate an area and facilitate an inflammatory response. After the inflammatory response, scar tissue will reabsorb, and new cells will be brought to the area with the intention of becoming healthy cells. Some of the new cells are collagen cells. The problem is that the collagen cells are typically laid down in an abnormal pattern, which can affect the skin’s ability to resist stretching and other forces. Therefore, it is very important to loosen the scar tissue so that normal cells can replace these cells in the normal alignment.
Although a therapist can mobilize the tissue by hand, it is most effective to use a tool for precise work to the area. This technique is safe and should not cause any increase in pain.
What to Expect During IASTM Treatment
Your therapist will first identify areas of restriction or tightness through assessment and palpation. A hypoallergenic emollient is then applied to the skin, and the instrument assisted soft tissue mobilization tool is used in a variety of techniques—such as sweeping, fanning, or brushing motions—targeted to the specific muscle, tendon, or fascia involved.
This may be followed by:
-
Stretching and active movement exercises to improve mobility and reinforce proper alignment
-
Neuromuscular re-education to retrain muscle activation patterns
-
Strengthening exercises to stabilize the surrounding structures
-
Home care instructions to promote continued progress between sessions
Although a therapist can mobilize tissue by hand, the use of an IASTM tool allows for greater precision and efficiency, especially in dense or fibrotic areas. This technique is safe, evidence-based, and should not cause an increase in pain. Some mild soreness—similar to what you might feel after a deep tissue massage—is normal and usually subsides within 24–48 hours.
