Answer

Fibonacci spiral

Answer

Parabolic curve

Answer

Elliptical model

Question 3

What does the term 'antalgic posture' mean in CBP spinal mechanics?

Accepted Answer

A posture adopted to reduce pain by shifting spinal loading

Answer

The ideal upright posture with balanced spinal curves

Answer

A posture caused by leg length inequality alone

Answer

A normal postural variant requiring no treatment

Question 4

In CBP, what is the primary mechanical consequence of a loss of cervical lordosis?

Accepted Answer

Increased compressive loading on anterior disc structures

Answer

Reduced cervical rotation range of motion only

Answer

Decreased intervertebral foramen size at all levels

Answer

Improved shock absorption through the spine

Question 5

The 'mirror image' principle in CBP refers to which treatment concept?

Accepted Answer

Positioning the patient in the exact opposite of their postural deformity during treatment

Answer

Using bilateral spinal adjustments simultaneously

Answer

Replicating the patient's posture on a mannequin for analysis

Answer

Applying equal force on both sides of the spine

Question 6

Which law of physics is most directly applied in CBP when calculating the moment arm effect of forward head posture?

Lever mechanics (torque = force × distance)

Answer

Newton's First Law of Inertia

Answer

Hooke's Law of Elasticity

Answer

Bernoulli's Principle
