Abstract

Background and Purpose: Physical activity is one of the promising interventions with positive effects on the quality of sleep and cognitive function in multiple sclerosis (MS) patients. With the development of various physical programs including combined physical-cognitive programs, it seems that this type of intervention may better affect neurodegenerative diseases, such as MS. Therefore, this study aimed to investigate the quality of sleep and psychomotor vigilance following combined aerobic-cognitive training (Brythonic) and conventional aerobic training (Aerotonic) in patients with MS.

Materials and Methods: Thirty patients (22 women and 8 men) with Relapsing-Remitting and Expanded Disability Status Scale (EDSS) less than four (Mean±SD; age, 36.66±9.36 years; height,164.5±6.3 cm; weight, 65.43±9.80 kg; body mass index, 24.02±3.02 kg/m²) were randomly divided into 3 equal groups of brythonic training, aerotonic training, and control. Subjects in brythonic and aerotonic groups performed 10 weeks of home-based online training, two sessions per week. Each exercise session included 10 minutes of warm-up, 15 to 35 minutes of exercise, and five minutes of cool-down. The activity of the brytonic group was to perform motivational words with aerobic movements in each session. During ten weeks, these words formed a complete sentence with a positive meaning. In the aerotonic group, the same aerobic movements as the braytonic group were performed, with the difference that there was no cognitive load. Before and after 10 weeks of training psychomotor vigilance test (PVT), and Pittsburgh Sleep Quality Index (PSQI) test were performed by all subjects in the three goups. Data analyses were prformed by using the repeated measures of ANOVA.

Results: Despite observing a relative improvement in most variables of the PVT in the brythonic group compared to the aerotonic and control groups, these changes were not significant (P>0.05). Although, in the PSQI test a 1-point improvement was observed in the sleep quality of patients in the brythonic and aerotonic groups, these changes were not significant.

Conclusion: This study showed that although the repetition of motivational words with aerobic exercise in a short training period does not have a significant effect on the quality of sleep and the levels of psychomotor vigilance of the patients with MS, because of improving trend in the brythonic training group, probably longer duration or higher intensity of exercise or cognitive interventions might result in significant changes.
