Key result
Hemispatial neglect and multiple swallowing features are linked to worse dysphagia outcomes after acute stroke.
Observational (n=65)
This retrospective study determined whether specific neurological features were associated with initial and final swallowing outcomes in acute stroke patients. A chart review of 65 acute stroke patients suggested that certain clinical and neurocognitive behaviors were associated with swallowing outcomes. Hemispatial neglect was significantly associated with initial nonoral dietary intake, whereas aphasia was not associated with swallowing outcome. Results from the initial clinical swallowing evaluations suggested that the presence of at least four of six clinical features (cough after swallow, voice change after swallow, abnormal volitional cough, abnormal gag reflex, dysphonia, and dysarthria) were associated with poor initial and final swallowing outcomes. Whether specific lesion location, size, or a combination of clinical neurological deficits are associated with poor initial and final swallowing outcomes is unclear. Prospective studies are warranted for further investigation of these relationships.

Schroeder et al. (2006) conducted an observational in Acute stroke (n=65). Clinical and neurocognitive features (including hemispatial neglect, aphasia, and 6 clinical swallowing features) vs. Absence of these clinical or neurocognitive features was evaluated on Initial and final swallowing outcomes (including initial nonoral dietary intake). Hemispatial neglect and having ≥4 of 6 clinical swallowing features in 65 acute stroke patients were associated with poor initial and final swallowing outcomes, whereas aphasia was not.
