Non-Systems NPTE Practice Exam

To correct anterior listing, you need a device that stabilizes both the trunk and the shoulders. A chest harness does this by wrapping across the chest and attaching to the shoulders, creating a posterior counterforce that keeps the trunk upright and the shoulders pulled back. This dual support helps prevent forward tipping of the torso and maintains proper scapular alignment, promoting an upright posture during seated activities.

A chest strap alone mainly restrains the torso and doesn’t provide active shoulder stabilization. Armrests, whether present or removable, primarily support the arms and don’t address the forward trunk lean. So they don’t correct anterior listing as effectively.
