What is NOT a characteristic response of CAT 3 during a rib head exam?

In the context of a rib head exam within the framework of Sacro Occipital Technique (SOT), CAT (Cranial Adjusting Technique) categories define specific response patterns observed during assessments. CAT 3 is characterized primarily by bilateral movement, as the body tends to present a more symmetrical response during evaluations.

The correct choice highlights that "no associated rib head movement" does not align with the characteristics seen in CAT 3. Typically, a CAT 3 response would display some level of movement, whether unilateral or bilateral, thus indicating the body's engagement and reaction during the examination.

Understanding the movement types helps clarify the physiological responses noted in patients. Bilateral movement is significant since it suggests that both sides of the rib cage are involved in the adjustment process, highlighting a coordinated movement pattern which can be vital for specific chiropractic evaluations.

This knowledge aids practitioners in making informed decisions during treatment and diagnosis, ensuring that they recognize when responses don't fit expected patterns, such as the lack of rib head movement in CAT 3, which can indicate a different underlying issue or the necessity for further examination.
