Ultrasound is one of the most common treatments used in the management of soft tissue injury.  

Ultrasound consists of inaudible high-frequency mechanical vibrations created when a generator produces electrical energy that is converted to acoustic energy through mechanical deformation of a piezoelectric crystal located within the sound head.  The waves of sound energy that are produced enter the tissue, and are absorbed at depths of 1-5 cm, depending on the frequency of the applicator: 1MHZ or 3MHZ.  

Therapeutic effects are caused by thermal and non-thermal effects, ultimately resulting in earlier resolution of inflammation, heightened fibroblast recruitment, and increased tissue tensile strength, all accelerating tissue healing and repair.  

Scientific studies are not conclusive on the benefits of ultrasound, but it has continued to be used over the past 70 years.  We use this and other modalities as an adjunct to treatment when indicated to gain whatever benefits it may have.
