Objective: To investigate the impact of the COVID-19 pandemic on physical activity in persons with multiple sclerosis (PwMS).Design: Multicenter international online survey study.Setting: The survey was conducted within 11 participating countries. Each country launched the survey using online platforms from May to July 2021.Participants: This was an electronic survey study targeting PwMS (N=3725).Intervention: Not applicable.Main Outcome Measures: The survey ascertained physical activity performance and its intensity, the nature of the activities conducted, and the use of technology to support home-based physical activity before and during the pandemic.
Results: A total of 3725 respondents completed the survey. Prepandemic, the majority (83%) of respondents reported being physically active, and this decreased to 75% during the pandemic.
This change was significant for moderate-and high-intensity activity (P<.0001). Activities carried out in physiotherapy centers, gyms, or pools decreased the most.
Walking was the most frequently performed activity prepandemic (27%) and increased during the pandemic (33%). A total of 24% of those inactive during the pandemic had no intention of changing their physical activity behavior post pandemic.
A total of 58% of the respondents did not use technology to support physical activity during the pandemic. Of those who did use technology, wearables were most used (24%).
Of those currently nonactive (25%) expressed a preference for an in-person format to con-duct physical activity post pandemic.Conclusions: Physical activity performance, especially activities at moderate and high intensities, decreased during the pandemic in PwMS com-pared with prepandemic. Walking and using wearables gained popularity as ways to stay active.
As we move toward an endemic COVID-19, a call for action to develop interventions focused on walking programs with specific emphasis on increasing physical activity of PwMS is proposed.
