  1. aDual tasking tests were performed with 34 patients; bStep length during self-selected walking speed was performed in 32 patients. Three measures were invalid and could not be repeated. The dual-tasking paradigm was performed with a) self-selected walking speed and b) dual-tasking (counting backwards from 100 in steps of 7 during self-selected walking speed
