Abstract: Although therapeutic ultrasound has been in existence since the 1930s, questions remain as to its effectiveness in promoting tissue healing in various injured tissues. These tissues include soft tissues such as skin, tendons, ligaments, bursae, joint capsules and muscles. Limited evidence exists to support a role for therapeutic ultrasound in closed, soft tissue lesions. However, an evolving literature provides support for the role of therapeutic ultrasound in the treatment of chronic wounds, acute injuries such as fractures and split thickness graft donor sites as well as in the modulation of wound-related pain. Modern technology that uses low-frequency (kilohertz), long wave ultrasound appears promising compared to older, higher frequency ultrasound (megahertz) devices. These newer devices appear to have positive effects on healing rates in various wound types, pain levels and the modulation of proinflammatory cytokines.
