McKenzie Method teaches assessment techniques using patient movements to assess the problem. His premise is that there are three causes of back pain. 1-Postural. 2. Dysfunction of the vertebral complex. 3-Derangement Syndromes. The assessment enables identification and clasification of the back pain. Treatment regimes follow depending on the classification of the back pain. Therapist input is fairly intensive at first requiring about 11-12 treatment sessions which consist of assisting the patient to learn and adjust as well as progress the exercises. It is very strong on patient education. While the emphasis is on patient self management there are times when further therapist is required eg nerve adherance, postural, or derangement problems on top of a derangement syndrome. Might be worth looking on the web. His name is Robin McKenzie, is from New Zealand and his courses are run through the McKenzie Institute all over the world. Thanks for your interest.
