Supplementary Figure 3 from Increasing cognitive load attenuates right arm swing in healthy human walking

Basic spatiotemporal parameters under increasing cognitive loads during treadmill walking in younger, middle-aged and older adults. Statistical significance was determined using a linear mixed model with post-hoc t-tests. P values are corrected for multiple comparisons within each age group using the Bonferroni method. Error bars indicate 1 standard error of the mean. CoV; coefficient of variation.
