Wurn technique/Clear Passage therapy-

This is a pair of husband/wife physical therapists who like many other physical therapists, name a technique after themselves, write a few low level studies without any controls, compare them to surgical outcomes, write a book, develop a franchise, and like McDonalds they are exporting this technique to the world.  They claim to be able to cure infertility, hip and back pain, abdominal adhesions, and an entire array of maladies with their mobilization therapy, really not very different claims that some other notorious physical therapy techniques.  There are ten publications in the scientific literature on this technique, none are randomized or are controlled trials.  They are of the nature “I did this technique to someone and they got better”, but of course they may have improved anyway or improved due to another therapy altogether unrelated to the “Wurn technique”.  Clear Passage is a solely owned company by the Wurns. 

Recommendation: while there is possible benefit to the therapy, it has no alpha level support or even beta level support.  The gamma level support makes outcomes speculative and subject to a placebo response.
