Question 1

In CBP, the normal cervical lordosis measured on a lateral radiograph is approximately how many degrees?

Accepted Answer

34 degrees

Answer

CBP establishes the normal cervical lordosis as approximately 34 degrees (Cobb angle C2–C7) based on geometric modeling of ideal spinal curvature.

Question 2

Which mathematical model does CBP use to describe the ideal spinal curvature?

Accepted Answer

Circular arc or Harrison posterior tangent method

Answer

CBP uses the circular arc model (Harrison posterior tangent method) to quantify and compare spinal curvatures to an ideal geometric standard.

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

An antalgic posture is one the body assumes to offload a painful structure, often resulting in lateral or sagittal imbalances that CBP aims to correct.

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

Loss of cervical lordosis shifts the head's center of gravity anteriorly, dramatically increasing compressive and shear forces on anterior disc and vertebral body structures.

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

The mirror image principle means the corrective exercise, traction, or manipulation posture is the precise geometric opposite of the patient's measured postural deviation.
