Key clinical point: Impaired respiratory muscle functions are linked to sleep disturbance and cognitive impairment in patients with multiple sclerosis (MS), warranting early evaluation of respiratory muscle strength.
Major finding: The respiratory muscle function test negatively correlated with the scores of Epworth Sleepiness Scale (ESS) and Perceived Deficits Questionnaire (PDQ) and showed a positive correlation with the Brief International Cognitive Assessment for Multiple Sclerosis (BICAMS) scale score ( P less than .001 for all).
Study details: The study assessed 146 MS patients with a mean age of 29.3 years and a mean Expanded Disability Status Scale (EDSS) score of 4.11.
Disclosures: This study did not receive any external funding. The authors declared no conflicts of interests.
