Feasibility of Dual-Task Gait Training for Community-Dwelling Adults after Stroke: A Case Series

Figure 2

Plots showing patterns of cognitive-motor interference for each participant for each cognitive-motor dual-task combination before and after the intervention. Dual-task effects (DTE) represent percent change relative to single-task performance and are calculated by dividing the difference between single-task and dual-task values by the single-task value, expressed as a percentage. Positive values for DTE indicate that performance improved in the dual-task condition relative to single-task performance; negative values for DTE indicate that performance deteriorated in dual-task condition relative to single-task performance. DTEg is DTE on gait speed; DTEc is composite DTE for the three cognitive tasks (reaction time and accuracy for Stroop and clock tasks, clauses per utterance and pauses per utterance for spontaneous speech task).
