Patient Assessment Flashcards

In CBP posture analysis, how many degrees of freedom are used to describe the position of a rigid body such as the head, thorax, or pelvis?

Answer: Six

CBP describes each posture with three rotations and three translations about the x, y, and z axes, for six degrees of freedom.

A patient's head sits forward of the thorax when viewed from the side. In CBP terminology, this is described as:

Answer: Anterior head translation (+Tz)

Forward shift of the head relative to the thorax along the z-axis is anterior head translation, written as +Tz.

Which radiographic mensuration method does CBP use to measure segmental and global cervical lordosis on a lateral film?

Answer: Harrison posterior tangent method

The Harrison posterior tangent method draws lines along the posterior vertebral body margins and is the CBP standard for sagittal curve measurement.

In the CBP ideal cervical spine model, the C2–C7 absolute rotation angle is about:

Answer: -42°

Harrison's ideal cervical model gives a C2–C7 absolute rotation angle (ARA) of about -42° of lordosis.

Which outcome questionnaire is most often used to track neck-specific disability in CBP cervical patients?

Answer: Neck Disability Index

The Neck Disability Index is a validated self-report measure of neck-related disability and is commonly used in CBP outcome studies.

In the CBP sagittal assessment, why should the lateral cervical radiograph be taken with the patient in a neutral standing posture?

Answer: To show the patient's habitual load-bearing alignment

Neutral standing films show the patient's habitual weight-bearing alignment, which is the baseline CBP corrects and re-measures.

Before CBP structural rehabilitation begins, which finding should lead to referral rather than treatment?

Answer: Progressive neurological deficit with bowel or bladder changes

Bowel or bladder changes with progressive neurological deficit suggest cauda equina or myelopathy and need urgent referral.
