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.

This study began development of a standard method that uses the videofluoroscopic swallow study for evaluation of swallowing recovery after stroke based on a definition of dysphagia derived from three domains: bolus timing, bolus direction, and bolus clearance. Two experiments were conducted: one that defined normal versus disordered swallowing based on the range of scores in a sample of healthy adults (n = 13), and one that applied these thresholds to nine stroke patients to identify the presence of dysphagia. Results indicate that acute and protracted dysphagia may be more accurately detected by identifying abnormalities on multiple objective measures of swallowing rather than on laryngeal penetration or aspiration alone. Results indicate that our selected measures and use of healthy control subjects to establish normal thresholds may eventually contribute to the definition and differentiation of dysphagic and nondysphagic patients. Further research with a broader sample of healthy controls and stroke patients is mandatory.
