The walls of the straw are thicker than in the other straws and, therefore, it can be used
multiple times and by patients with a strong bite.
The straw is sold without the lip blocks.
The difficulty in drawing liquid through the straws increases as your child or client moves up the hierarchy. Straw #1 is the easiest, #8 is the most difficult.
The hierarchy promotes jaw-lip-tongue dissociation.
Straw is an excellent device for abdominal grading' training, lip protrusion and rounding, tongue retraction.
