Supplementary Figure 1 from Increasing cognitive load attenuates right arm swing in healthy human walking

Effect of cognitive load on ASI for the entire cohort (n = 119), separated into three groups based on inclusion status. Only individuals exhibiting an ASI between -20 and 20 were included in the final analysis. Low baseline ASI; excluded group exhibiting a right-dominant ASI during normal walking of < -20 (n=8). High baseline ASI; excluded group exhibiting a left-dominant ASI during normal walking of > 20 (n=28). ASI is given as the mean value per gait cycle over a trial of 45 seconds (approximately 42 gait cycles at 4kmh-1). Error bars represent 95% confidence intervals. ASI; arm swing symmetry index.
