PAS Postural Deviations & Pathologies 3

Question 1

The Cobb angle is the standard radiographic measurement used to quantify the degree of which spinal deviation?

Accepted Answer

Lateral scoliotic curvature

Answer

The Cobb angle is drawn on X-ray between lines parallel to the most tilted vertebrae at the ends of a scoliotic curve, quantifying its lateral magnitude.

Question 2

Which landmarks define ideal postural alignment along the plumb line from a lateral view?

Accepted Answer

Lateral malleolus, mid-knee, greater trochanter, acromion, and earlobe

Answer

Ideal lateral alignment has the plumb line passing through the lateral malleolus, mid-knee, greater trochanter, shoulder (acromion), and earlobe.

Question 3

What does a rib hump observed during Adam's forward bend test clinically confirm?

Accepted Answer

Vertebral rotation associated with scoliosis

Answer

A rib hump appears because vertebral rotation in scoliosis pushes the posterior rib cage upward on one side, confirming the rotational component of structural scoliosis.

Question 4

Forward head posture is clinically quantified by measuring the horizontal distance the ear (tragus) is positioned relative to which landmark?

Accepted Answer

Anterior to the acromion process

Answer

Forward head posture is measured as the horizontal distance the tragus of the ear is located anterior to the acromion process.

Question 5

Which postural deviation is most strongly associated with increased compressive stress on lumbar facet joints and elevated risk of low back pain?

Accepted Answer

Anterior pelvic tilt with hyperlordosis

Answer

Anterior pelvic tilt with hyperlordosis increases compressive forces on lumbar facet joints and posterior disc structures, significantly raising low back pain risk.
