PRC Postural Assessment & Biomechanical Analysis 2

Question 1

During a PRI postural assessment, a patient demonstrates a left AIC pattern. Which combination of findings is most consistent with this presentation?

Accepted Answer

Right stance, left swing, left forward shaft femur

Answer

Left stance, right swing, right forward shaft femur

Answer

Right stance, left swing, right forward shaft femur

Answer

Bilateral stance with symmetric femoral positioning

Question 2

Which muscle is considered the primary driver of the left AIC (Anterior Interior Chain) pattern according to PRI principles?

Accepted Answer

Left iliopsoas

Answer

Right gluteus maximus

Answer

Right iliacus

Answer

Left tensor fascia latae

Question 3

A PRI-trained clinician observes that a patient cannot perform a left Adduction Drop Test. What does this suggest about the left hip?

Accepted Answer

Left hip cannot achieve abduction and external rotation simultaneously

Answer

Left hip abductors are overactive

Answer

Left hip adductors are inhibited

Answer

Left hip is locked in flexion

Question 4

In PRI biomechanical analysis, what is the significance of the 'zone of apposition' (ZOA) of the diaphragm?

Accepted Answer

It refers to the portion of the diaphragm in direct contact with the inner lower rib cage

Answer

It describes the area of the diaphragm that attaches to the spine

Answer

It is the central tendon attachment site

Answer

It represents the crural fibers of the diaphragm only

Question 5

When assessing the Right Brachial Chain (BC) pattern, which thoracic and rib cage finding would the clinician expect?

Accepted Answer

Right thoracic rotation with right rib flare and left rib depression

Answer

Left thoracic rotation with left rib flare

Answer

Symmetric thoracic rotation with bilateral rib flare

Answer

Left thoracic rotation with bilateral rib depression

Question 6

During postural assessment, a clinician notes the patient's right ASIS is lower than the left and the right PSIS is higher than the left. What pelvic pattern does this describe?

Accepted Answer

Right anterior ilial rotation

Answer

Right posterior ilial rotation

Answer

Left anterior ilial rotation

Answer

Bilateral anterior pelvic tilt

Question 7

According to PRI principles, why is the right hemidiaphragm considered biomechanically advantageous compared to the left?

Accepted Answer

It sits higher due to liver support, providing greater ZOA and mechanical advantage

Answer

It has more muscle fiber attachments to the spine

Answer

It has a larger central tendon

Answer

It has direct attachment to the right ilium
