Dr. Barbara Hungerford is a physiotherapist practicing in Australia where she founded the educational group Advanced Manual Therapy Associates.
She completed a Ph.D. on the “altered pelvic biomechanics and muscle recruitment patterns associated with pelvic dysfunction.”
Now, Dr. Hungerford runs educational courses for medical professionals such as physical therapists and osteopaths on what is called manual therapy, which basically means hands-on treatment. (The muscle energy technique is one example of manual therapy).
Dr. Hungerford has written some really great articles on the SI joint and the pelvis in general.
My favorites are Lumbopelvic Stability and Back pain. Whats the link? and The Integrated Pelvis– In my opinion, these are the articles which are most accessible to the average person.
However, her other articles are super fascinating, too! They include:
