PRC Postural Assessment & Biomechanical Analysis 3

Question 1

When performing the Hruska Adduction Lift Test (HALT), what does a score of '1' on the right side indicate?

Accepted Answer

Minimal right hip adduction with significant trunk compensation

Answer

A HALT score of '1' indicates the patient can only achieve minimal hip adduction with significant compensatory trunk movement, reflecting poor right hip and pelvis positioning.

Question 2

In PRI assessment, what does 'AF IR' stand for and what is its clinical significance?

Accepted Answer

Anterior Femoral Internal Rotation — the femur rotates inward relative to the acetabulum

Answer

AF IR (Acetabular-Femoral Internal Rotation) describes the femur rotating internally within the acetabulum, which is a key positional variable in PRI pattern recognition.

Question 3

A patient in a left AIC + right BC + left PEC (Posterior Exterior Chain) pattern complex is assessed. Where would the clinician most likely find rib cage asymmetry?

Accepted Answer

Right rib flare with left thoracic depression and leftward rotation of lower thorax

Answer

The combination of right BC and left PEC creates right rib flare, left thoracic depression, and a leftward-rotated lower thorax due to competing chain tensions.

Question 4

During gait analysis using PRI principles, what is expected to occur at the right hip during left stance phase in a neutral pelvis?

Accepted Answer

Right hip should be in extension, abduction, and external rotation

Answer

During left stance phase (right swing), the right hip should achieve extension, abduction, and external rotation to allow proper weight transfer and contralateral stepping.

Question 5

What is the primary purpose of assessing the 'trunk shift' during a PRI postural examination?

Accepted Answer

To identify the direction the thorax has shifted relative to the pelvis, reflecting chain pattern

Answer

Trunk shift assessment identifies lateral displacement of the thorax relative to the pelvis, which reflects the dominant PRI chain pattern pulling the thorax to one side.
