Instrument assisted soft tissue mobilization (IASTM) is a safe and effective technique that every practitioner should have in their repertoire. However, learning the technique and buying the correct tool for you are two different things. Buying an IASTM instrument is like buying a new car - research must be done! You have to "test drive" these instruments to determine which one fits your treatment approach, your hand size, and your budget. It has to be practical, affordable, and effective.
