OBJECTIVE: To review the current evidence regarding correlates and determinants
of physical activity (PA) in persons with multiple sclerosis (pwMS). DATA SOURCES: PubMed and Scopus (1980 to January 2015) and reference lists of eligible
studies. STUDY SELECTION: Eligible studies include adults with multiple
sclerosis; have a cross-sectional or prospective observational design; or examine
the effect of a theory-based intervention trial on PA, including a mediation
analysis. Eligible studies also apply a quantitative assessment of PA and
correlates or proposed mediators and are published in English or German language.
DATA EXTRACTION: Two reviewers independently evaluated the risk of bias,
extracted data, and categorized variables according to the International
Classification of Functioning, Disability and Health. DATA SYNTHESIS: Consistency
and the direction of associations were evaluated with a semiquantitative
approach. Fifty-six publications with data from observational studies and 2
interventional studies provided evidence for 86 different variables. Consistent
correlates of PA were the disability level, walking limitations in particular,
PA-related self-efficacy, self-regulation constructs, employment status, and
educational level. One interventional study provided evidence for a causal
relation between self-regulation and PA. However, 59 of the 86 investigated
variables in observational studies are based on 1 or 2 study findings, and most
results stem from cross-sectional designs. CONCLUSIONS: Beside the importance of
the general disability level and walking limitations, the results highlight the
importance of personal factors (eg, PA-related self-efficacy, self-regulatory
constructs, sociodemographic factors). Limitations and implications of the
current review are discussed. Research that is more rigorous is needed to better
understand what affects PA in pwMS.
