Alterations in gait variability among older adults with cerebral small vessel diseases (CSVD) during single (S) and dual (D) task conditions. The impact of task condition on Coefficient of Variation (CV) of Step Time [CV_T, panel (A)] and Step Length [CV_L, panel (B)] are shown for CSVD (n = 11; orange square symbols) and age- and sex-matched control (CONT, n = 11; light blue circle symbols) groups, respectively. (C) Log-transformed CV_T significantly differs between CONT and CSVD group for dual task condition (two-way RM-ANOVA, p = 0.006; Šidák’s multiple comparisons test, p = 0.009). (D) Log-transformed CV_L significantly differs between CONT and CSVD group (two-way RM-ANOVA, p = 0.006) for single task conditions (Šidák’s multiple comparisons test, p = 0.017). Symbol and error bar depict mean ± SD. *p < 0.05, **p < 0.01.
