Abstract

Study Design: Retrospective cohort study.

Objective: To determine the risk factors associated with dysphagia in individuals with cervical spinal cord injury (CSCI) and analyze the differences between individuals with improved penetration-aspiration (PA) and persistent PA on follow-up.

Setting: Tertiary inpatient rehabilitation facilities.

Methods: Medical records of individuals with CSCI admitted between December 2009 and February 2023 who underwent a videofluoroscopic swallowing study (VFSS) were retrospectively reviewed. Multivariate logistic regression analysis was performed to assess risk factors for dysphagia. Differences between individuals with improved PA and persistent PA were analyzed using an independent t-test.

Results: In total, 149 participants were enrolled. Age (odds ratio (OR) 1.08, 95% confidence interval (CI) 1.04-1.12), percentage of forced vital capacity to predicted normal (FVC (% predicted)) (OR 0.90, 95% CI 0.85-0.94), and skeletal muscle index (OR 0.89, 95% CI, 0.79-0.99) were significant factors associated with the risk of PA. Based on the receiver operating characteristic curve analysis, the cut-off values for age, FVC (% predicted), and skeletal muscle index were determined as 56.0, 45.7, and 41.0, respectively. A secondary analysis of the follow-up VFSS was conducted on 38 participants. The follow-up FVC (% predicted) and degree of weight loss differed significantly between the improved PA and persistent PA groups.

Conclusions: Older age, low FVC (% predicted), and low skeletal muscle index can be predictors of dysphagia in patients with CSCI. On follow-up VFSS, individuals with improved PA demonstrated greater improvement in FVC (% predicted).
