Plumb-line postural analysis is most limited for postural distortions within what plane?

Question

Quizplus · Accepted Answer

Plumb-line postural analysis is most effective for identifying postural distortions in the sagittal and frontal planes, such as forward head posture or lateral spinal deviations. It is limited in its ability to detect distortions in the transverse plane, such as rotations or twists of the body or limbs, because these movements occur around a vertical axis and are not easily observed from a side or front view.
