I read a 2011 paper, Low-intensity pulsed ultrasound reduces the inflammatory activity of synovitis. that mention that ultrasound can help reduce inflammation.
However, Save Yourself article states:
Unfortunately — although there are some interesting exceptions and tantalizing hopes for some conditions — ultrasound is not a promising therapy for most musculoskeletal conditions. There is a jarring, bizarre lack of research for such a popular therapy. What little research is available paints an overwhelmingly bland picture. And the principle of US itself is, at best, much more complicated and unpredictable than most therapists believe. At worst, there is no rational basis for US at all. Ultrasound therapy is almost certainly useful for some patients, some of the time — but it is not a reliable or evidence-based therapy.
So, does ultrasound work to reduce inflammation (e.g. treat musculoskeletal problems, especially inflammation such as tendonitis and bursitis)?
