 A significant increase in PPW bulging was seen with the maneuver at both 
pharyngeal levels. These findings indicate potential for developing new 
treatment techniques to facilitate compensatory anterior movement of the PPW, 
which has not been a target for direct treatment in the past. At present, the 
tongue-holding maneuver can be employed clinically as an easy method for testing
 the compliance of the PPW videofluorographically. However, the use of the
