PURPOSE: To identify and synthesize the research evidence concerning (1) the
relationship between physical activity and cognitive performance in persons with
multiple sclerosis (MS) and (2) to review the reported effects of physical
activity interventions on neurocognitive performance conducted in this
population. METHODS: Relevant peer-reviewed journal articles were identified by
searching PubMed, PsychINFO, and SPORTDiscus through May 2016. Full-text articles
meeting the inclusion criteria were evaluated for quality using tools developed
by the National Institutes of Health. Studies deemed to be of poor quality were
excluded from the review. RESULTS: Nineteen studies meeting the
inclusion/exclusion criteria were analyzed. Nine studies reported significant
relationships between higher levels of physical activity or cardiorespiratory
fitness and measures of cognitive function. Data extracted from 10 physical
activity intervention studies reported mixed results on the effectiveness of
physical activity to improve selected domains of cognitive function in persons
with MS. CONCLUSION: Although correlational studies provide evidence to support a
linkage between physical activity and cognitive function in persons with MS, this
linkage is confounded by factors that may have influenced the studies' results.
Evidence derived from intervention studies that could support a positive effect
of physical activity on cognition in persons with MS is equivocal. Implications
for Rehabilitation Physical activity has numerous benefits for persons with
multiple sclerosis (MS) including improvements in balance, ambulation,
depression, fatigue, and quality of life. Structured physical activity programs
may contribute to cognitive function stability or improvement in persons with MS.
