   OroPress is a new, low profile, portable, wireless tool that enables stable measurement of tongue pressure during isometric (‘pushing’) tasks and, more importantly, during swallowing.  Using this tool, a pressure-time product, the OroPress Absolute (OPA) parameter, has been developed as a representative measure of lingual effort during swallowing. 

   In a sample of 57 adults aged 20-80+ years, of both sexes and without dysphagia, tongue-palate contact pressures generated while swallowing 5ml, 10ml of water and 5ml custard, were recorded using OroPress. Data were examined for effects of gender, age and bolus condition (consistency, volume). OPA was tested for stability of measure and then correlated with the criterion standard, peak pressure recorded when swallowing (PMaxSW).

   Swallowing pressures (PMaxSW;OPA) were positively correlated with bolus viscosity. No significant age and gender differences were found.  Excellent stability of measure (test, re-test reliability) was demonstrated and OPA was positively correlated with PMaxSW.

   OroPress produces valid, reliable and reproducible measurements and improved accuracy of oro-lingual pressure measurement during swallowing.  With such a tool, interventions/ therapy can be proactive and principled as outcomes are better validated. To enhance specificity of intervention, measurement parameters need to reflect the pressure and temporal qualities of swallow function.  OPA has the potential to describe differences in effort made, and ability to sustain pressures, in adults without dysphagia.
   The results of these studies will enable more accurate examination of the oral phase of swallowing as we establish this highly accurate sensor as a criterion standard for oro-lingual pressure measurement in clinical populations.
