What does the non-neutral plane indicate during evaluation?

The correct answer highlights that the non-neutral plane indicates a restricted range of motion. In osteopathic structural practice, the evaluation of spinal mechanics often involves determining whether the spine is in a neutral or non-neutral position. When the spine is described as being in a non-neutral plane, it suggests that there are limitations in the mobility of the vertebral segments.

In this context, a non-neutral position typically occurs when the spine is flexed or extended, creating a situation where the normal range of motion is compromised due to muscular or ligamentous restrictions, joint dysfunctions, or other structural changes. This limited ability to move freely signifies that certain motions may be constrained, which is crucial information for practitioners when diagnosing and developing treatment plans.

Understanding this concept helps practitioners identify areas requiring intervention, as enhancing mobility in restricted segments may be essential for restoring function and reducing discomfort.
