"What IASTM is, is not, and might be" is a recent post by Leonard van Gelder via his Dynamic Principles Blog. In this post, he discusses his usage of the EDGE Tool, why he uses it and the controversy surrounding using different instruments in his treatment sessions. First off, it is important to note that there is not a great deal of evidence surrounding IASTM. While major IASTM companies report high levels success, the amount of published articles does not directly correlate with these claims.
A few of these reported health benefits include regarding IASTM:
1. Activating the histamine response and triggering localized tissue inflammation
2. Scar Tissue (Type III Collagen) breakdown and "realigning fibers"
3. Promoting collagen synthesis by promoting fibroblast proliferation
Of those reported benefits (above), increasing fibroblast proliferation is the only property that has been consistently demonstrated through various research articles. With that said, the current studies have mainly been performed on rat MCL's with little evidence supporting long term differences in collagen synthesis whether or not IASTM was used.
In conclusion, it is important to remember that regular mobility of an affected area helps increase lubrication and maintains critical fiber distance. Whether it be from hands on techniques or the use of an instrument, it is important to keep structures mobile. As Goodman and Fuller state, "Immobilization is associated with excessive deposition of connective tissue in associated areas. This is accompanied by a loss of water and subsequent dehydration. The result is an increase in intermolecular cross-linking, which further restricts normal connective tissue flexibility and extensibility." When using Graston tools, the back edge of spoon, or the EDGE Tool, one must remember their intent behind treating with an instrument. In other words, what are you really trying to change or modify? The body of knowledge surrounding IASTM is limited, but being informed about what it is and maybe is a step in the right direction.
