Which statement is a specific benefit of backward sitting?

• A. Increases jaw grading (facilitates lingual disassociation and vowel production) and closure
• B. Provides a larger base of support
• C. Reduces upper extremity weight bearing
• D. Decreases thoracic extension

Answer: (A)

Backward sitting helps create a stable, well-supported trunk and pelvis, which provides the proximal stability needed for precise oral-motor control. When the torso is steadied, the nervous system can better organize jaw and tongue movements, allowing fine-grained jaw grading and the ability to dissociate the tongue from the jaw. This supports better lip closure and more accurate vowel articulation. The other statements describe benefits that aren’t specifically tied to this position’s effect on oromotor control—such as simply increasing base of support, reducing upper-extremity weight bearing, or altering thoracic extension—so the jaw/lingual coordination and vowel production improvement is the most specific and relevant outcome of backward sitting.
