Differences in cognitive and locomotor DTI
Mori et al. (24)	Oval walkway	T-Test Trunk linear accelerations      DTI stroke > DTI healthy control	Serial subtraction (-3)	T-Test Correct response rate      DTI stroke = DTI healthy control Mistake rate      DTI stroke > DTI healthy control
Kemper et al. (29)	Oval walkway	Mixed-design ANOVA Cadence      DTI Stroke = DTI healthy control Time on task      DTI Stroke > DTI healthy control	Spontaneous speech	According to the authors Fluency: DTI stroke > DTI healthy control Grammatical complexity:      DTI stroke > DTI healthy control Semantic content:      DTI stroke > DTI healthy control
Hyndman et al. (28)	Forward walking	Mixed-design ANOVA Walking time      DTI Stroke > DTI healthy control Walking speed      DTI Stroke = DTI healthy control Stride length      DTI Stroke = DTI healthy control	Auditory memory	Mixed-design ANOVA      DTI stroke > DTI healthy control
Differences in locomotor DTI only
Manaf et al. (30)	Timed-Up-and Go	Mixed-design ANOVA Walking time      DTI Stroke = DTI healthy control Stride length      DTI Stroke = DTI healthy control Walking speed      DTI stroke > DTI healthy control Stride time      DTI stroke > DTI healthy control Coefficient of variability of walking speed      DTI Stroke = DTI healthy control Coefficient of variability of stride length      DTI Stroke = DTI healthy control Coefficient of variability of stride time      DTI Stroke = DTI healthy control	Serial subtraction (-3)*	Mixed-design ANOVA Number of repeated trials      DTI Stroke = DTI healthy control Number of correct responses      DTI Stroke = DTI healthy control
Differences in cognitive DTI only
Pohl et al. (32)	Oval walkway	T-Test Cadence      DTI stroke = DTI healthy control	Spontaneous speech	T-Test Rate speech      DTI stroke = DTI healthy control Fluency      DTI stroke = DTI healthy control Semantic content      DTI stroke = DTI healthy control Grammatical complexity      DTI stroke > DTI healthy control
No differences in DTI
Al-Yahya et al. (25)	Treadmill	Mixed-design ANOVA Stride length      DTI Stroke = DTI healthy control Cadence      DTI Stroke = DTI healthy control	Serial subtraction (-7)	Mixed-design ANOVA Counting rate      DTI Stroke = DTI healthy control Accuracy      DTI Stroke = DTI healthy control
Chan and Tsang (26)	Back and forth (180°)	T-Test Turning time      DTI Stroke = DTI healthy control Number of steps to turn      DTI Stroke = healthy control Completion time      DTI Stroke = healthy control	Auditory stroop test	T-Test Reaction time      DTI Stroke = DTI healthy control Accuracy      DTI Stroke = DTI healthy control
