So if we say that the cause of most low back pain is not understood, it should mean that we do not know what mechanism is causing the low back pain most of the time. But that is not true. We can often palpate tight myofascial tissue or a dysfunctional joint that is causing back pain.
The application of this study is enormous. Many manual therapy professions employ joint mobilization techniques, either Grade IV and/or Grade V.
A joint functions to allow motion, so two forms of joint dysfunction exist: Hypomobile joint has restricted motion; Hypermobile joint has excessive motion.
Grades IV and V joint mobilization are essentially pin and stretch technique.
Bone “A” is pinned and then Bone “B” is moved relative to Bone “A.”
