Abstract

UNLABELLED: Purpose/Objective Research: This study examined combinations of disease outcomes (i.e., walking, cognition, and symptoms) as correlates of physical activity subgroups (insufficiently active vs. sufficiently active) in persons with multiple sclerosis (MS).

RESEARCH METHOD/DESIGN: This study included 213 participants who completed walking and cognitive function tests and self-report measures of symptoms and physical activity. Multivariate analysis of variance and discriminant function analysis identified combinations of MS outcomes associated with physical activity.

RESULTS: The sample had a mean age of 49.6 years (

CONCLUSION/IMPLICATIONS: The findings identified walking endurance and limitations, processing speed, depression, and fatigue as primary correlates of physical activity differences in persons with MS. These results may inform researchers and health care providers to consider these factors in behavior change interventions and clinical practices for promoting adequate physical activity levels in MS.
