Perceptions of physical activity guidelines among wheelchair users with multiple sclerosis.

Background: Physical activity guidelines provide prescriptive resources for population-level promotion of behavior change to improve health outcomes. The National Multiple Sclerosis Society (NMSS) recently created and disseminated physical activity guidelines for persons with multiple sclerosis (MS) across the disease spectrum. Objective: This study aimed to assess perceptions of the updated NMSS Physical Activity Guidelines among wheelchair users with MS. Methods: One hundred thirty-four wheelchair users with MS participated in a cross-sectional study examining health behaviors. Outcomes were measured using an online questionnaire that included items related to demographic and clinical characteristics and a battery of questions regarding perceptions of the NMSS Physical Activity Guidelines based on Expanded Disability Status Scale groups 7.0-7.5 & 8.0-8.5. Results: Among the 134 participants, 77 participants (58%) did not meet the general recommendations, 43 participants sometimes meet the general recommendations (32%), and 14 participants (10%) reported meeting the general recommendations. Participants reported positive perceptions across modalities (i.e. Breathing, Flexibility, Upper Extremity, Lower Extremity, and Core Exercises); however Upper and Lower Extremity Exercises were rated as the most challenging based on inability to complete independently. Conclusion: Wheelchair users with MS in this study generally rated the NMSS Guidelines for Physical Activity as appropriate.
