Graston’s Technique
Instrument Assisted Soft Tissue Mobiliztion (IASTM)
Graston is a form of instrument assisted soft tissue mobilization also known as IASTM. The Graston technique uses a particular set of instruments along with a certain progression of strokes and application. Often called scraping as a general term, there are several different methods or theories behind it. Graston is the technique we use here at Sports Medicine Solutions.
Graston can be used to help mobilize soft tissue and scar tissue using several different techniques. The idea is that we are scraping along the surface of the skin separating the layers of tissue (fascia, muscle, skin, etc). This will lead to better overall extensibility of the tissue allowing for improved exercises and stretches afterwards.
Common Myth
Myth: People think that Graston should be painful and will most likely leave bruising or petechiae (red dots from burst capillaries).
Fact: The pain during treatment should never get above a 4/10 on the pain scale and any discoloration should be minimal except for slight reddening of the skin during treatment.
How It Works
The reddening of the skin indicates blood flow increased to the area which will literally warm the tissues causing increase in extensibility. The reddening from fresh blood to the area will bring new healing factors to the injury area.
The other way that scraping works is by modulating the nervous system's sensation response in the area. We use this technique with scar tissue or after a neurologic injury, giving stimuli to the dermatomes (the nerve endings that senses touch/pain/temperature). The goal is to recalibrate what is felt and should be able to decrease the sensation of pain over time.
