The effects of a volitional breathing technique on swallowing and respiratory coordination in individuals with amyotrophic lateral sclerosis: A pilot investigation

  • Individuals with amyotrophic lateral sclerosis (ALS) often present with aberrant respiratory-swallowing relationships. In this pilot study, eight individuals with ALS learned a volitional breathing technique designed to promote safe swallowing. The primary focus of the study was to evaluate the effectiveness of the technique in (1) promoting expiratory breathing after swallowing and (2) improving patients’ perceptions of swallowing. As a group, the participants showed a statistically significant increase in the average number of typical swallows (expiration after swallowing) following training. With regard to perceptions of swallowing, there were no obvious differences between participants’ baseline and post-treatment quality of the life scores on a questionnaire; however, participants’ responses to qualitative interview questions were generally positive and suggest that participants found the treatment technique to be beneficial and effective in improving their safety and comfort while swallowing.
