IASTM is a variation of traditional cross fiber (transverse) friction massage. It is a form of treatment used to “break up” or “soften” scar tissue, thus allowing for a return of normal function in the area being treated. The beveled edge of the instrument combined with its concave/convex shapes to mold the instrument to various contours of the body. This design allows for ease of treatment, maximum tissue penetration in a gentle manner, and minimal stress to the chiropractor’s hands. Much like a tuning fork, this instrument resonates in the clinician’s hands allowing the doctor to isolate adhesions and restrictions and treat them very precisely. Since the metal surface of the instruments do not compress like the fat pads of the finger, deeper restrictions can be accessed and treated. When explaining the properties of these instruments, we often use the analogy of a stethoscope. Just like a stethoscope amplifies what the human ear can hear, so do the instruments increase significantly what the human hands can feel.
