I think that as an adjunct treatment, the use of U/S has a place in PT practice. While there is lacking evidence to support the use of it, I believe that it is quite a reasonable therapeutic agent out there for heating deeper tissues. Other EPA’s are simply either too expensive (ie. SWD), or ineffective for heating deeper tissues (i.e heat packs). Therefore, I would argue that depending on what the goals are for treatment, and what tissues you are trying to target, ultrasound could be used.
