PRC Muscle Imbalance & Pattern Recognition Flashcards

In Postural Restoration, the Left AIC pattern primarily involves which finding?

Answer: Left innominate in anterior rotation with left hip internal rotation

The Left AIC pattern features a left innominate in anterior rotation with associated left hip internal rotation and compensatory right hip external rotation.

Which muscle is considered a primary driver of the Right BC (Brachial Chain) pattern in PRI?

Answer: Right pectoralis minor

The right pectoralis minor is a key driver of the Right BC pattern, pulling the right shoulder into a forward and depressed position.

In the typical PRI asymmetrical human presentation, which femur is most commonly found in a relatively forward or anterior position?

Answer: Left

In the typical PRI asymmetrical pattern, the left femur is positioned more anteriorly due to left AIC involvement and associated left innominate anterior rotation.

The PEC pattern in PRI refers to which myofascial chain?

Answer: Posterior Exterior Chain

PEC (Posterior Exterior Chain) is a bilateral pattern involving posterior pelvis and thorax overactivation with associated respiratory and lumbar extension dysfunction.

Which muscle imbalance is most characteristic of a left-sided AF IR (Acetabular Femoral Internal Rotation) limitation in PRI?

Answer: Overactive right adductors and left hip external rotators limiting left femoral internal rotation

Left AFIR limitation is characterized by overactive right adductors pulling the pelvis and overactive left hip external rotators preventing adequate left femoral internal rotation.

In PRI, the TMCC pattern refers to which chain?

Answer: Temporal Mandibular Cervical Chain

The TMCC (Temporal Mandibular Cervical Chain) involves the relationship between the jaw, cervical spine, and associated myofascial structures linking craniofacial to cervicothoracic regions.
