Multiple Sclerosis, Fatigue, Expanded Disability Status Scale: A Cross-Sectional Exploration of Sleep Efficiency and Quantitative Sleep Parameters

Abstract Background Poor sleep quality and disorders are more prevalent in individuals with multiple sclerosis (MS) than the general population. has been correlated worse MS outcomes. Sleep efficiency (SE) is one of most sensitive markers quality. There very little written about SE other polysomnography (PSG) parameters measures. Methods This a retrospective review 280 consecutive evaluated by PSGs standardized measures over 13 years at comprehensive center. In addition, cohort was assessed 2 fatigue scales, Epworth Sleepiness Scale, Expanded Disability Status Scale. A comparison means test (independent t test) r, or correlation coefficient, were used. Results The PSG Total Time significantly different between group disease duration 5 vs less then equal to years. Prevalence obstructive apnea 63%, higher reported literature while prevalence moderate severe 33.4%, which lower reported. Conclusions Longer as well disability correlate measured SE.
