What is the stress test for CAT 2?

The stress test for Category 2 (CAT 2) in Sacro Occipital Technique (SOT) involves evaluating the body's response to specific positions and movements that help identify mechanical imbalances or dysfunctions. The correct choice, which involves extending the arm out to the side and raising each leg for evaluation, directly assesses how the body manages weight distribution and stability, particularly focusing on the lower extremities in relation to pelvic and spinal function.

In this context, raising each leg while the arm is out assists in observing compensatory patterns and motor control within the pelvic area. This is crucial for identifying the type of dysfunction that might be present and determining the appropriate treatment approach based on the patient's response.

The other options, while they involve movements that could also be informative, do not specifically align with the established procedures for CAT 2 stress testing. For instance, having the arm out to the front or incorporating quick leg raises might not provide the same level of insight into the pelvic and hip mechanics being scrutinized in CAT 2 evaluations. Thus, the core focus on side positioning and leg raising is essential for proper assessment within this category.
