There are many tools out there that can be used for IASTM (instrument assisted soft tissue mobilization). This is not an inherently new technique. It stems from gua sha, a traditional Chinese medicine technique that has been practiced for over 2,000 years. I first was trained in school in Graston Technique, which uses stainless steel tools and an emollient to promote glide. Recently, I decided to try a different set of tools out. I took the Rock Blades seminar in May 2018. I chose these tools because they are more focused on the neurosensory effect of treatment instead of beating up the tissue. There are three different types of Rock Blades that I use in the office. They are all made of surgical stainless steel. The Mohawk is unique in that it also has a silicone sleeve and a snap on comb. The silicone sleeve is used for tissue gripping, which creates a shearing effect between the skin and tissue beneath. The comb is used to affect the nervous system. It acts like a form of dry brushing and can be used to reduce localized pain, improve kinesthetic awareness and proprioception of the body. It also facilitates lymphatic fluid flow and drainage. With these tools, depending on the pressure, pattern, and stroke, we are trying to modulate pain, up regulate, down regulate, or produce tissue glide in our muscles, fascia, ligaments, or tendons. Initially, IASTM tools were used to only “release” an area. We currently know that does not truly occur and where the actual benefits occur is from making positive changes in our nervous system.
