I agree with both ChelseaB and kmcahoon’s points above. On the basis that there is strong support for the thermal effects of ultrasound, as well as the benefit of building a therapeutic relationship and the psychosocial benefits it may have on the patient, I believe there is a place for ultrasound in physical therapy. For some patients ultrasound may provide better treatment effects than one that has more clinical evidence in its favor. However, it is important to have sound reasoning in your choice to use ultrasound and to be aware that some of the effects, such as decreasing pain, have more clinical evidence than others, such as treatment of acute ankle sprains. Until the research provides therapists with more sound evidence for or against U/S, clinical experience is sometimes all we have.
