title: The association between physical activity and sleep characteristics in people with multiple sclerosis.
abstract: OBJECTIVE
  The majority of individuals with multiple sclerosis (MS) suffer from sleep disorders. In this study, we investigated the relationship between physical activity and sleep characteristics in MS patients.
  
  
  METHODS
  Sixty MS patients were recruited in the study. Sleep characteristics were assessed using the Actisleep device while physical activity levels were assessed using mobility accelerometer.
  
  
  RESULTS
  The results showed that means (±SD) of sleep latency (SL) and sleep efficiency (ES) for MS patients were 23.89±13.23min and 87.52±76.89% respectively. The participants' total time in sleep (TST) and wake after sleep onset (WASO) were 353.25±63.98min and 83.84±42.23min respectively. With respect to physical activity levels, means (±SD) of light (LA), moderate (MA), vigorous (VA) activities and moderate to vigorous physical activity (MVPA) were 11,660.15±18,145, 212.04±148.67, 9.70±9.26 and 222.88±154.60 counts per minute, respectively. Pearson's correlation analysis showed that WASO correlated significantly with LA, MA and MVPA (P<0.05). These correlations remained significant even after accounting for age, body weight and disease severity (P<0.05).
  
  
  CONCLUSIONS
  The results show a positive relationship of physical activity with sleep parameters in individuals with MS.
