“…For example, a study that investigated VC and RC in patients following stroke found that they were independent of each other and that VC was impaired in 79% of right-handed patients who had suffered acute left-sided middle cerebral artery (MCA) infarcts but CR remained unimpaired and no patients developed aspiration pneumonia (Stephens et al, 2003). A similar study investigating VC and RC in stroke patients found that 10% of patients had a weak or absent CR, whereas 20% of patients had an abnormal VC (Addington, Stephens, & Gilliland, 1999). Addington et al (2005) also suggest that cerebral infarcts can result in transient, or permanent, 'brainstem shock' which can result in impaired cough reflex.…”

“…It has been demonstrated that cough gastric pressures are normal in patients following stroke, whereas respiratory measures of coughing strength, including flow rate and expired volume, are reduced (Addington et al, 1999). It was hypothesized that gastric measures of coughing are not indicative of actual coughing strength as they do not encompass measurement of impairment at the upper airway.…”

“…Impairments of respiratory muscle function when measured by volitional tests and reductions in voluntary cough flows and gastric pressure in stroke patients have been described previously [26,27], but demonstration of a cough deficit, which may be considered more important for airway protection and clearance, is novel. An interesting finding was that despite patients achieved normal reflex cough gastric pressures, flow rates and expired volumes for reflex cough were both decreased.…”

Cough is defensive airway reflex subjected to a high degree of cortical control. Not surprisingly, all cough motor patterns can be mimicked and reflex cough be inhibited up to complete suppression, at least to a certain extent. Reflex cough differentiates from other airway reflex responses for its characteristic 3-phase motor pattern, and such pattern is maintained when coughing is produced voluntarily. Despite these and some other similarities, voluntary and reflex cough differ in many important respects, suggesting different neural control of the respiratory and non-respiratory musculature implicated in the generation of the cough modalities. This paper focuses the motor features that differentiate voluntary and reflex cough efforts, and highlights the importance of functional assessment of coughing in the diagnostic workup of respiratory and extra-respiratory diseases affecting the production of voluntary and reflex cough.

“…Dystussia is related to risk for aspiration and respiratory failure in people with neuromuscular dysfunction. [3][4][5][6][7][8] It is well known that dystussia can occur due to weakness of the inspiratory and/or expiratory respiratory muscles. 2 In particular, weakness of the abdominal muscles results in difficulty generating sufficient pressure for a forceful, effective cough.…”
