Mean (SD) values for the gait parameters in normal walking (no cognitive task) and the four cognitive dual tasks conditions: nonspatial (NS) easy, NS difficult, visuospatial (VS) easy and VS difficult for the 36 participants.

ANOVA results examining main and interaction effects of task type and difficulty are also presented.
an = 35; erroneously high data for one participant excluded from the analysis of this variable.
Note: There were also significant effects of added cognitive load (p<0.001) for all gait parameters, with each dual task condition (VS-easy, VS-diff, NS-easy, NS-diff) producing significantly slower gait speeds, shorter step lengths, reduced cadence, increased step time variability and reduced harmonic ratios compared with the no cognitive task walking condition (one-way repeated measures ANOVAs with planned contrasts p≤0.001).
