Ultrasound, interferential current and tens are widely used in rehabilitative therapy throughout the world. It is reported that in the United States alone, five billion dollars are spent on ultrasound therapy annually. Most independently motivated therapists are aware that minimal benefit derives from these techniques. At best, they act as counter-irritants, create a temporary increase in circulation and the release of endorphins. They are definitely not a factor in the healing process despite producing temporary relief of symptomotology.

Laser therapy, on the contrary, is effective in restoring tissue to its normal state, i.e., it acts to reverse the pathology and therby relieves symptoms. Initially there is a varying degree of pain relief due to the release of endorphins and cortisol produced by the body itself, but the more important effect is the cumulative factor, which is curative over the course of a series of treatments. These may vary from one treatment to as many as twenty. Each case is as individual as are the responses to therapy. More over, in most instances, patients activities need not be restricted as healing continues while activity goes on.
