Category I patterns are often misunderstood unless you are evaluating through a dural and neurological lens.
When you find bilateral rib-head pain with hypermobility, frequently accompanied by an anterior SI joint fixation, you are not simply looking at a thoracic complaint. You are observing a compensatory mechanism.
In a Category I primary meningeal subluxation pattern, this hypermobility often represents the body’s attempt to facilitate pumping of cerebrospinal fluid. The system is creating motion where it can in order to maintain neurological function.
If you only address the ribs locally, you miss the underlying meningeal imbalance.
Evaluate the indicators. Confirm the pattern. Adjust specifically.
That is the difference between chasing symptoms and correcting neurological dysfunction.
