Respiratory-swallow coordination is imperative to prevent aspiration of foreign material into the airway. Swallowing events typically occur during the expiratory phase of respiration; this is thought to facilitate laryngeal vestibule closure to prevent entry of material into the airway, and promote post-swallow clearance of any material that has penetrated into the laryngeal vestibule. By contrast, inspiration immediately post-swallow presents as a risk for aspiration. Individuals with respiratory impairment, such as those who have sustained a spinal cord injury, may experience changes in respiratory-swallow coordination, affecting their safety during oral intake. The focus of this dissertation was to explore the relationship between swallowing and respiration in the spinal cord injury (SCI) population. This was investigated in three phases: 1) a systematic review of current literature describing swallowing impairment and the efficacy of behavioural interventions in the SCI population; 2) a prospective study evaluating respiratory-swallow coordination in healthy young adults across a range of different liquid consistencies; and 3) a prospective study evaluating respiratory-swallow coordination in the SCI during a drinking task with 5 different liquid consistencies. Considered altogether, this work was able to provide novel contributions to the field of dysphagia research. This dissertation revealed a gap in knowledge about swallowing pathophysiology in the spinal cord injury population, with a need for high quality studies assessing the effectiveness of behavioural interventions in this population. The work of this dissertation was able to confirm stable respiratory-swallow relationships for healthy young adults across five liquid consistencies and provide reference data for respiratory phase pattern and pause duration. Finally, this dissertation provided evidence of changes in swallowing efficiency and respiratory-swallow coordination in the SCI population. These results demonstrate a need for further evaluation of the swallowing and respiratory subsystems in this population to establish clinical guidelines for assessment and intervention.
