Carrie Tollefson is an American middle distance runner who was on the US 2004 Summer Olympic team. She suffered from plantar fasciitis and used a Sonocur for her treatment back in 2003 before the Olympics. Here is an article from Running Times Magazine about her comback : http://runningtimes.com/Article.aspx?ArticleID=3764

In terms of treatment, Tollefson’s medical team left no known mode of plantar fasciitis therapy untried: iontophoresis, cortisone shots, acupuncture, active-release therapy, icing, and Sonorex shockwave treatments from Dr. Bill Roberts, which Tollefson credits more than anything else with her eventual recovery.
