IASTM
Instrument Aided Soft Tissue Manipulation
IASTM stands for Instument Aided Soft Tissue Manipulation, and may also be called ASTYM or Graston. Both ASTYM and Graston are specific types of IASTM, much like Xerox is a type of copier. IASTM is used extensively in the outpatient orthopedic setting due to the results generated with the technique.
