Some relevant excerpts to this question:
"Robert Ward suggested that the direct method came from the osteopathy school in the 1920s by William Naidner called Fascial Twist. Dr. Ida Rolf developed Structural Integration in the 1950s...
"Teachings of direct myofascial release was kept in the school and only available privately until recently (in the 1990s) where texts and courses are offered to general bodyworkers: Art Riggs, Michael Stanborough, Tom Myers, and others.
"The indirect technique originated in osteopathy schools and also popular in physical therapy. German physiotherapist Elizabeth Dicke developed Connective Tissue Massage (Bindegewebbsmassage) in the 1920s with superficial stretching of the myofascia. According to Robert C. Ward, myofascial release originated from the concept by Andrew Taylor Still, the founder of Osteopathic medicine in the late 19th century. The concepts and techniques were subsequently developed by his successor including Dr. William Sutherland, and until 1980s they were popularised by osteopaths and physiotherapists. Robert Ward further suggested that the term "Myofascial Release" as a technique was coined in 1981 when it was used as a course title in Michigan State University. Initially Myofascial Release was popular among physical therapists in the US. John F. Barnes built on the indirect techniques in combination with CranioSacral therapy and made it to public in the 1980s by providing training to massage and other manual therapists."
