National Board of Chiropractic Examiners (NBCE) Practice Test

The adjustment procedure pictured (right PSIS push), using a PA and IS line of drive, is used to correct a/an ___________ malposition of the ilium.

1. Anterior

2. Posterior

3. Inferior

4. Superior

The correct answer is: Posterior

The right PSIS push adjustment procedure utilizes a posterior-to-anterior (PA) and inferior-to-superior (IS) line of drive primarily to correct a posterior malposition of the ilium. In chiropractic practice, the ilium can become misaligned, and when it is positioned too far posteriorly relative to its normal alignment, a corrective adjustment is necessary to restore proper function and motion. In this context, the PA line of drive implies that the force is directed from the back (posterior) toward the front (anterior), while the IS component further indicates that the adjustment aims to elevate the ilium, which has shifted posteriorly. Correcting a posterior malposition is essential for restoring proper pelvic mechanics and spine alignment, which can alleviate related dysfunctions and discomfort. Understanding this adjustment's purpose clarifies the necessity of employing specific lines of drive to effectively target the posterior malposition, thereby aiding in restoring overall patient health and biomechanical balance.
