IASTM is a technique used to treat soft tissue restrictions (i.e., knots or scar tissue). It involves scraping an area of restriction with controlled pressure using stainless steel, jade, or plastic tools. As the instruments glide over the skin, they provide tactile feedback, allowing me to detect subtle changes in tissue texture. When restriction is found, focused and controlled pressure is applied to the area in a scraping-like manner to stimulate the smoothing of adhesions.
TCM views health as dependent on the free movement of qi (life force energy) through meridians, or energy channels. When qi or blood becomes stagnant, it can lead to pain, tension, or illness. Gua sha, the scraping technique used in TCM, is used to break up stagnation, remove toxins, and restore health.
As mentioned, IASTM works by detecting and treating areas of adhesions (thickened or bound tissues). Adhesions can develop due to surgery, repeated strain, or poor movement and can restrict movement and cause pain. The scraping action over the skin is thought to kickstart the immune system, sparking a natural healing process. More specifically, the tool triggers a small amount of microtrauma and inflammation to the local tissues. This process stimulates the remodeling of the affected soft tissue.
The tools also increase local blood flow and stimulate local sensory receptors, which can desensitize a painful area.
Following an IASTM session, some people do report feeling mild local soreness. Most people claim to feel a bit "lighter" and have improved range of motion in the joints that neighbor the treatment area.
Some people, depending on the intensity of the session and their skin tone, will notice mild redness or pinpoint bruising. These marks are called petechiae (they are not bruises). The scraping action of the tool creates friction on the skin, leading to a small amount of blood to leak from superficial capillaries. The leak finds its way to the skin, leaving a hickey-like appearance. The marks are a normal and temporary reaction to the scraping stimulus and tend to fade within a few days.
IASTM has shown promise for the treatment of a variety of conditions, including:
Muscle strains
Sprains
Scar tissue from injuries or surgeries
Plantar fasciitis
Tendonopathy (Achilles, patellar, etc.)
Trigger finger
There are times when IASTM would not be appropriate. A few of these conditions/issues include:
Open wound
Bleeding disorder such as hemophilia
Uncontrolled hypertension
Hematoma
Unhealed fracture
