Physical Activity in Multiple Sclerosis (MS): A Novel Approach to Study Outcomes

Summary

Physical activity and exercise interventions in multiple sclerosis (MS) have received great attention most recently and there exists several randomized clinical trials (RCTs) addressing the outcomes associated with such intervention. The majority of such interventions have primarily focused on directly influencing disease processes (e.g., inflammation, neurotrophic factors), the reduction of symptoms (e.g., fatigue, depression), improvement in physical functioning (e.g., gait, strength) or enhancing one's quality of life. To date, the evidence suggests that exercise intervention in MS holds anywhere from minimal to great promise depending on the outcome of interest. For some outcomes such as depression or cognition, findings are even less optimistic, being null, or inconsistent, at best. These inconsistent findings may be attributed to methodological issues such as use of subjective reports, lack of appropriate control group, poor compliance, and sample selection. The proposed investigation aims to address some of these issues by: (1) Obtaining objective measures of outcomes of interest (i.e., fatigue, cognition, and participation/activities of daily living \[ADLs\]) and; (2) assessing certain person-specific factors (e.g., personality) and intermediary factors that may be influenced by physical activity and indirectly result in improved outcomes (e.g., improvement in sleep and subsequent improvement in fatigue and/or cognition). Thus, the primary objective of the proposed investigation is to: (1) utilize innovative and objective measures of outcomes and; (2) obtain comprehensive assessment of intermediary variables (e.g., sleep) or person-specific characteristics (e.g., personality), which together may explain the inconsistent findings in the literature and has the following specific aims:

To achieve these goals, individuals will complete a comprehensive assessment of cognition, person-specific factors, intermediary factors, physical fitness, and functional magnetic resonance imaging (fMRI) prior to and following a home based exercise intervention.
