Objective: The purpose of the study was to understand how people with multiple sclerosis experience dual-tasking situations in their everyday lives. Methods: Focus groups involving a total of 11 individuals with multiple sclerosis (eight females and three males) participated in this qualitative inquiry. Participants were asked open-ended questions focused on the nature of and consequences around dual tasking when standing or walking. Reflexive thematic analysis was employed to examine the data. Results: Three themes were generated from the data: (a) Life Is a Dual Task, (b) The Social Divide, and (c) Sacrifices for Stability. Conclusions: This study highlights the significance and impact of dual tasking on the lived experience of adults with multiple sclerosis, furthering the need to more fully examine this phenomenon and potentially improve fall-prevention interventions and facilitate community participation.

The present study expands on current understanding of dual-task cognitive-motor interference, by including cortical activation measures to both traditional and ecologically valid dual-task paradigms. Fifteen individuals with multiple sclerosis and 14 control participants underwent mobility testing while wearing functional near-infrared spectroscopy. In the absence of increased prefrontal cortical activation, subjects with multiple sclerosis performed significantly worse on measures of cognition under both single- and dual-task conditions. These findings suggest that persons with multiple sclerosis may be unable to allocate additional cortical resources to cognition under dual-task conditions, leading to significant cognitive-motor interference and decrements in performance. This study is the first to investigate cortical activation across several commonly used and ecologically valid dual-task assessments. [ABSTRACT FROM AUTHOR]
