Read the first 6 PRC Muscle Imbalance & Pattern Recognition flashcards as text

  1. Which test is used in PRI to assess Left AIC pattern resolution?

    Answer: 90/90 hip lift test

    The 90/90 hip lift test evaluates the patient's ability to achieve a neutral pelvic position with left hamstring activation, serving as a key marker of Left AIC pattern resolution.

  2. Inhibition of which muscle is a primary goal when addressing the Right BC pattern in PRI treatment?

    Answer: Right pectoralis minor

    Inhibiting the right pectoralis minor reduces the forward shoulder pull that drives the Right BC pattern, allowing restoration of right thoracic rotation.

  3. In PRI pattern recognition, bilateral patterns such as PEC are generally considered:

    Answer: More complex and harder to resolve than unilateral patterns

    Bilateral PRI patterns like PEC are generally more complex, involving both sides of the body and requiring more comprehensive treatment to restore normal alternating function.

  4. The Right AF ER (Acetabular Femoral External Rotation) finding in PRI indicates:

    Answer: The right femur is positioned in relative external rotation within the acetabulum

    Right AF ER describes the right femur being positioned in relative external rotation within the acetabulum, a common finding in the typical Left AIC asymmetrical pattern.

  5. Which finding on a forward bending test would suggest a Right-on-Right sacral torsion in PRI assessment?

    Answer: Left lumbar convexity with right sacral base elevation

    A Right-on-Right sacral torsion presents with a left lumbar convexity and right sacral base elevation on forward bending, reflecting the sacrum rotating on the right oblique axis.

  6. Over-activation of the right hamstring in PRI patterns is most commonly associated with:

    Answer: Left innominate anterior rotation with compensatory right innominate posterior rotation via right hamstring

    In the Left AIC pattern, the right hamstring compensates by posteriorly rotating the right innominate as the left innominate anteriorly rotates, creating the characteristic asymmetrical pelvic position.
