Reflexive Coughing Force in Severe Aspirators
The Summary of Purpose was updated.
New
To assess coughing force during reflex coughing test in those with severe dysphagia and severe aspiration and compare them to than those with stroke patients with no signs of dysphagia/aspiration.
Old
To assess coughing force during reflex coughing test in those with dysphagia and determine if those with silent aspiration (SA)have more compromised coughing force during reflex cough testing than those with non-silent aspiration (NSA).
The description was updated.
New
Severe aspiration with a compromised cough function can be a risk factor of aspiration pneumonia. Reflexive coughing can be tested by administration of citric acid via a nebulizer. The objective of this study is to measure the cough force produced via citric acid inhalation challenge, and determine if those with severe aspiration with severe dysphagia have more weak cough force during reflexive cough testing that those post-stroke patients with no signs of aspiration or dysphagia after stroke. We also aimed to measure the strenght of the respiratory measures with the use of surface EMG.
Old
Silent aspiration (SA) can be a risk factor of aspiration pneumonia. SA has been reported to occur in over 40% of patients referred for dysphagia evaluation in a rehabilitation hospital. Reflexive coughing can be tested by administration of citric acid via a nebulizer. The objective of this study is to measure the cough force, and determine if those with SA have more weak cough force during reflexive cough testing.
The eligibility criteria were updated.
