Question 1

In PRI, the Zone of Apposition (ZOA) is defined as the area of the diaphragm that:

Accepted Answer

Lies in apposition to the inner aspect of the lower rib cage

Answer

The ZOA refers to the portion of the diaphragm that is in direct apposition (contact) with the inner lower rib cage, which is critical for optimal pressure generation and trunk stability.

Question 2

Which movement pattern is most associated with a patient who presents with a right dominant Left AIC (Anterior Interior Chain) pattern?

Accepted Answer

Right hip anterior tilt with left thoracic side-bending

Answer

The right dominant Left AIC pattern typically presents with a right hip anterior tilt and left thoracic side-bending as compensatory adaptations.

Question 3

During normal gait, the right hemidiaphragm descends during which phase as the right foot contacts the ground?

Accepted Answer

Loading response

Answer

During loading response (initial contact of the right foot), the right hemidiaphragm descends to contribute to trunk stabilization and load transfer through the thorax.

Question 4

The posterior mediastinum's role in PRI neuromuscular patterning is primarily related to:

Accepted Answer

Generating left thoracic rotation to counterbalance right dominance

Answer

The posterior mediastinum acts as a left thoracic rotator, helping to counterbalance the natural right-sided dominance seen in typical postural patterns.

Question 5

A patient cannot maintain a neutral pelvis during a supine 90-90 hip lift test. This most likely indicates inadequate activation of which muscle?

Accepted Answer

Left internal oblique

Answer

The left internal oblique is critical for maintaining a neutral left pelvis during the 90-90 hip lift; failure to activate it allows the pelvis to rotate right into a Left AIC pattern.
