Swallowing and respiratory impairments in Parkinson's disease (PD) may contribute to atypical respiratory–swallowing phase patterning. This exploratory study aimed to (a) quantify swallowing impairment and airway protection, (b) determine respiratory–swallowing phase pattern at swallow initiation, and (c) test the association between swallowing impairment, airway protection, and respiratory–swallowing phase pattern in PD.

Conclusion
PD patients demonstrated greater frequency of swallows initiated during inspiration with higher MBSImP and maximum PAS scores relative to healthy controls. Replication of these findings in large, homogenous PD samples may clarify the relevance for retraining typical respiratory–swallowing phase patterning benefiting swallowing improvement.
