👇The two most common causes of aspiration are....
B) Decreased laryngeal elevation and delayed triggering of the pharyngeal motor response
A study across 5 institutions evaluated 166 dysphagic patients referred for a modified barium swallow.
When researchers looked at what was actually driving that aspiration, two physiologic causes stood out above the rest: decreased laryngeal elevation and delayed triggering of the pharyngeal motor response.
In plain terms: the airway wasn't closing enough, or it wasn't closing fast enough.
Either way, the bolus had a laryngeal opening it shouldn't have had!
This matters because it points treatment in a specific direction.
If delayed initiation and reduced laryngeal elevation are among the most common mechanical causes of aspiration....
👀...then the swallow exercises you choose should directly target the speed and strength of hyolaryngeal movement, not just general "swallow strengthening."
🔥And THAT'S EXACTLY what Ampcare targets, y'all!!
