PRC Neuromuscular Integration & Movement Patterns 3

Question 1

The Posterior Exterior Chain (PEC) in PRI refers to the integration of which primary structures?

Accepted Answer

Hamstrings, gluteus maximus, thoracolumbar fascia, and posterior shoulder complex

Answer

The PEC integrates the hamstrings, gluteus maximus, thoracolumbar fascia, and posterior shoulder girdle as a continuous myofascial chain influencing extension and rotation patterns.

Question 2

During a PRI-based step test, a patient shows an inability to shift weight left. This is most commonly associated with:

Accepted Answer

Inability to achieve left acetabular-femoral orientation due to right AIC patterning

Answer

Difficulty shifting left during the step test typically reflects the right AIC pattern where the left acetabulum cannot properly orient over the femoral head to accept load.

Question 3

Which of the following describes the neuromuscular role of the left adductor magnus in PRI theory?

Accepted Answer

It acts as a hip extensor-internal rotator that counters right pelvic forward rotation

Answer

The left adductor magnus is emphasized in PRI as a key hip extensor and internal rotator that counters the forward rotation of the right pelvis seen in the Left AIC pattern.

Question 4

A PRI clinician observes that a patient's left rib cage is more elevated and externally rotated than the right. This finding is most consistent with:

Accepted Answer

Right TMCC pattern influencing the left thorax

Answer

The Right TMCC (Temporal Mandibular Cervical Chain) pattern can influence thoracic cage positioning, and right temporal-cervical dominance often correlates with left thoracic cage elevation.

Question 5

In PRI gait analysis, the left gluteus medius ideally fires during which phase to stabilize the pelvis?

Accepted Answer

Right loading response through mid-stance, when the right foot is on the ground

Answer

The left gluteus medius must fire during right loading response and mid-stance to prevent contralateral (right) pelvic drop and maintain proper pelvis position over the left stance limb.
