PRC Neuromuscular Integration & Movement Patterns 2

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

Contracts concentrically during forced exhalation

Answer

Attaches directly to the lumbar vertebrae only

Answer

Functions independently of intra-abdominal pressure

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

Left hip internal rotation with right thoracic rotation

Answer

Bilateral hip external rotation with lumbar flexion

Answer

Right hip posterior tilt with left pelvic drop

Question 3

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

Accepted Answer

Loading response

Answer

Terminal swing

Answer

Pre-swing

Answer

Mid-stance

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

Providing attachment for the right AIC muscle chain

Answer

Limiting cervical extension range of motion

Answer

Resisting diaphragmatic descent on both sides equally

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

Right iliopsoas

Answer

Left hamstring

Answer

Right quadratus lumborum

Question 6

In PRI, the Right BC (Brachial Chain) pattern contributes to which characteristic cervical-thoracic posture?

Accepted Answer

Left cervical side-bending with right thoracic rotation

Answer

Right cervical side-bending with left thoracic rotation

Answer

Bilateral cervical flexion with thoracic kyphosis

Answer

Right cervical extension with left lateral trunk shift

Question 7

Which of the following best describes reciprocal inhibition as it pertains to PRI postural patterns?

Accepted Answer

Neural inhibition of an antagonist when the agonist contracts, reinforcing patterned asymmetry

Answer

Co-contraction of agonist and antagonist to stabilize a joint

Answer

Simultaneous activation of bilateral muscle groups during gait

Answer

Reflex relaxation of a muscle following a quick stretch stimulus
