Jaw Thrust Oral Motor Problem
suddenly and with force. Typically, the jaw is able to move up and down, shift, move laterally, rotate, and hold patterns in various graded positions and strengths.
These movements enable sucking, biting, chewing, and develops to more defined movement patterns. As a result, we are able to bite with graded motions, hold jaw positioning, move food within the mouth, manage various food textures, and control the tongue, lips, and cheeks. When jaw thrust is present, the jaw is held in a downward and outward position.

jaw thrust can occur for several reasons:
Increased patterns of muscle tone
Poor sitting posture
Impaired breathing patterns leading to
compensatory positioning resulting in jaw thrust
Over-stimulating sensory environment
- · Hyper-reaction to input from teeth contacting
each other during biting and chewing
Jaw thrust impacts components of eating,
including sucking, biting, swallowing, and chewing food.
Jaw thrust impacts the movement and use of the tongue, cheeks, and lips as a result of jaw thrust.
When a child eats, jaw thrust interferes with
the rhythm of eating and drinking.
Children may present with a strong jaw thrust during meals and the
person who is feeding the child views the jaw thrust as food refusal or being
through with eating.
Jaw thrust may result in drooling, food droppage or spilling, spilling or leaking of fluids.
