How does S.A.S.T.M. work?

It is theorized that S.A.S.T.M. is effective because of the following:

Instruments effectively break down fascial restrictions and scar tissue. The ergonomic design of these instruments provides the doctor with the ability to locate restrictions through sound waves. This allows the clinician to treat the affected area with the appropriate amount of pressure, due to square surface concept. Restrictions within the soft tissue, which may have developed as a result of surgery, immobilization, repetitive strain injuries, are broken down allowing full functional restoration to occur.
