Physiotherapy use and access-barriers in persons with multiple sclerosis: A cross-sectional analysis

•Physiotherapy (PT) may alleviate multiple sclerosis symptoms, yet little is known about usage and barriers.•PT usage was studied based on self-reports of 1493 Swiss Multiple Sclerosis Registry participants.•PT usage was higher in persons with primary-progressive MS, higher symptom burden, or recent stays at a rehabilitation clinic.•No association between PT supply and percent PT users per Swiss canton was detected.•PT uptake differences were observed by language region, which warrant further investigations.
