- W2883362998 abstract "<b><i>Background:</i></b> Specific dual-task (DT) training is effective to improve DT performance in trained tasks in patients with dementia (PwD). However, it remains an open research question whether successfully trained DTs show a transfer effect to untrained DT performances. <b><i>Objective:</i></b> To examine transfer effects and the sustainability of a specific DT training in PwD. <b><i>Methods:</i></b> One hundred and five patients with mild-to-moderate dementia (Mini-Mental State Examination: 21.9 ± 2.8 points) participated in a 10-week randomized, controlled trial. The intervention group (IG) underwent a specific DT training (“walking and counting”). The control group (CG) performed unspecific low-intensity exercise. DT performance was measured under three conditions: (1) “walking and counting” (trained); (2) “walking and verbal fluency” (semi-trained), and (3) “strength and verbal fluency” (untrained). Outcomes evaluated at baseline, after training, and 3 months after the intervention period included absolute values for the motor and cognitive performance under DT conditions, and relative DT costs (DTCs) in motor, cognitive and combined motor-cognitive performance. <b><i>Results:</i></b> The IG significantly improved DT performances in the trained condition for absolute motor and cognitive performance and for motor, cognitive, and combined motor-cognitive DTCs compared to the CG (<i>p</i> ≤ 0.001–0.047; <i>ηp</i><sup>2</sup> = 0.044–0.249). Significant transfer effects were found in the semi-trained condition for absolute motor and partly cognitive performance, and for motor but not for cognitive DTCs, and only partly for combined DTCs (<i>p</i> ≤ 0.001–0.041<i>;</i> <i>ηp</i><sup>2</sup> = 0.049–0.150). No significant transfer effects were found in the untrained condition. Three months after training cessation, DT performance in the trained condition was still elevated for most of the outcomes (<i>p</i> ≤ 0.001–0.038; <i>ηp</i><sup>2</sup> = 0.058–0.187). Training gains in the DT performance in the semi-trained condition were, however, not sustained, and no significant group differences were found in the DT performance in the untrained condition after the follow-up. <b><i>Conclusion:</i></b> This study confirmed that specific DT training is effective in improving specifically trained DT performances in PwD and demonstrated sustainability of training-induced effects for at least 3 months. Effects were partially transferable to semi-trained DTs but not to untrained DTs. With increasing distance between trained and untrained DTs, transferability of training effects decreased." @default.
