Abstract
This review discusses research on physical and cognitive function, physical activity behavior, and physical activity interventions in older adults with multiple sclerosis (MS). Research indicates that older adults with MS demonstrate reduced physical and cognitive function as well as physical activity compared with healthy older adults. Preliminary evidence suggests that levels and patterns of physical activity are associated with physical function and possibly cognition, and physical activity interventions can improve physical function in older adults with MS. Additional research is warranted that further clarifies the value and role of physical activity in managing the functional consequences of aging with MS.
