OBJECTIVE: To test the hypothesis that oropharyngeal air-pulse application is
associated with increased swallowing rates in individuals with dysphagia
secondary to stroke. DESIGN: Case control. SETTING: Stroke rehabilitation
hospital or home setting. PARTICIPANTS: Convenience sample of individuals (N=8)
with new-onset dysphagia after stroke. INTERVENTIONS: Air-pulse trains were
applied to the oropharynx of 8 subjects who presented with dysphagia after
hemispheric stroke. Resting swallowing rates were determined for 5 experimental
conditions: baseline without air-pulse mouthpiece, baseline with mouthpiece in
situ, unilateral right oropharyngeal air-pulse, unilateral left oropharyngeal
air-pulse, and bilateral oropharyngeal air-pulse application. Individual
swallowing responses were analyzed using a 2-SD band method. MAIN OUTCOME
MEASURE: Swallowing rate (swallows/min). RESULTS: Swallowing rates associated
with bilateral air-pulse application were greater than baseline in 4 of the 8
subjects. The 4 subjects who demonstrated this response to air-pulse application
had greater baseline swallowing rates than did subjects whose swallowing rates
were not altered in association with air-pulse application. CONCLUSIONS:
Oropharyngeal air-pulse trains can be applied in individuals with swallowing
impairment. Air-pulse application is associated with increased resting swallowing
rates in some individuals with dysphagia secondary to hemispheric stroke. Further
research should extend this proof-of-principle study by examining the efficacy of
oropharyngeal air-pulse application in terms of improved swallowing and related
outcomes in dysphagic stroke through a large randomized trial.
