Article: The effects of head positioning on pressure generation in the pharynx during normal swallowing: A pilot study

PURPOSE-We seek to compare forces generated in the pharynx and applied to the bolus during normal swallows with various clinically used altered head positions and compare these data to previously obtained data on normals without altered head positions. We shall then use these comparisons to establish a normative database regarding forces on the bolus for later studies evaluating dysphagic patients. Along with this, we are working to develop and perfect the operations of a Manofluorographic Laboratory at the Atlanta VA Medical Center.

The prototype instrumentation used to obtain force measurements in this investigation adds a new quantitative dimension to the traditional evaluation and ...
