TMJ in Joint by Joint

....asked where the TMJ joint would fit into Coach Boyle's Joint by Joint Theory....I will have to look at the algorithm, but my impression is that the jaw is a stable joint.Here's why, and it's just semantics because the fact of the matter is that all joints require both mobility and stability.Using Sahrmann as a foundation, pain abounds from something that moves too much. So when we consider "stable" joints, these are the joint systems (not always just 1 joint) that have problems when there is hypermobility. Stability can be defined as control of a segment in the presence of potential change. That does not mean lockdown isometric mid-range "stability." Based off the hypermobility prevalence of TMJ, I would consider it a stable joint system.And if we use the O-A joint as mobile, the TMJ is supposed to be stable.The cervical spine is really debatable, and it simply lends to the credence that the Joint by Joint is more a theory and constructive way to think more than a steadfast biomechanical map.But the fact of the matter is that it does work out in the alternating fashion almost any way you crunch it.
