Mirror Image Adjusting Techniques Flashcards

During a Mirror Image lumbar adjustment for a right rotational deformity, the corrective rotational force should be applied toward the:

Answer: Left rotation, opposite to the right deformity

Mirror Image protocol requires applying the corrective force in the left rotational direction to counteract the existing right rotational spinal deformity.

Harrison's Mirror Image concept in CBP is grounded in which mechanical principle?

Answer: Viscoelastic creep — sustained loads in the corrective direction produce plastic deformation of spinal soft tissues

CBP mirror image traction and exercises exploit viscoelastic creep, applying sustained corrective loads so that spinal ligaments and discs undergo plastic (permanent) deformation toward normal alignment.

In CBP practice, mirror image postures (held positions) are typically maintained for a minimum of how long per session to initiate viscoelastic tissue remodeling?

Answer: 10 to 20 minutes

CBP traction and mirror image postures are typically held for 10–20 minutes per session to reach the creep phase of viscoelastic tissue deformation and initiate structural change.

Which radiographic measurement confirms successful progress in a CBP cervical mirror image traction program?

Answer: Increase in the cervical Cobb angle toward the Harrison normal of approximately 34°

In CBP, improvement in cervical lordosis is quantified by the Cobb angle increasing toward Harrison's established normal of approximately 34°, confirming successful structural correction.

For a patient with an anterior head translation (forward head posture), the Mirror Image traction setup would position the head in:

Answer: Posterior translation relative to the trunk to oppose the anterior displacement

Anterior head translation is corrected by setting the traction device to apply a posterior translatory force on the head, the direct mirror image of the forward displacement.

Which table design feature is most essential for performing full-spine CBP Mirror Image adjusting?

Answer: Segmented drop pieces and articulating sections that can be configured to pre-load the spine into mirror image positions

CBP adjusting tables have segmented, articulating sections so each spinal region can be independently pre-loaded into the mirror image corrective position before the thrust.

In the CBP Mirror Image system, what is the term for the idealized spinal alignment that serves as the reference standard for identifying deformities?

Answer: Harrison Spinal Model (HSM) or Harrison Normal

The Harrison Spinal Model (HSM) provides the mathematical, geometry-based normal alignment standard against which patient X-rays are compared to identify the exact deformity requiring mirror image correction.
