Ultrasound Therapy Therapeutic Ultrasound Thermal and Non Thermal Effects Overview One of the therapeutic effects for which ultrasound has been used is in relation to tissue healing. It is suggested that the application of US to injured tissues will, amongst other things, speed the rate of healing & enhance the quality of the repair (Watson 2006). The following information is intended to provide a summary of some of the essential research in this field together with some possible mechanisms through which US treatments may achieve these changes. It is not intended to be a complete explanation of these phenomena or a comprehensive review of the current literature. It may, none the less, provide some useful basic information for clinical application. Some of the 'wider' applications for ultrasound therapy (e.g. drug delivery, chemotherapy potentiation) are usefully reviewed in Paliwal and Mitragotri (2008). The therapeutic effects of US
