Utilizing Pulmonary Function Parameters to Predict Dysphagia in Individuals With Cervical Spinal Cord Injuries

This study aimed to determine if lung function could predict swallowing difficulties (dysphagia) in people with cervical spinal cord injuries (CSCIs). The researchers reviewed medical records of 78 individuals with CSCIs, assessing lung function with spirometry and peak flow meters, and swallowing function via videofluoroscopic swallowing studies. The study found that lower values of peak cough flow (PCF) and forced expiratory volume in 1 second (FEV1) were associated with a higher risk of dysphagia in individuals with CSCIs.

• 1
  Individuals with a history of tracheostomy, anterior surgical approach, and higher neurological level of injury had significantly more penetration-aspiration or pharyngeal residue.
• 2
  Individuals in the penetration-aspiration group had significantly lower peak cough flow (PCF) levels.
• 3
  Individuals in the pharyngeal residue group had a significantly lower forced expiratory volume in 1 second (FEV1).
