, & Winter, 1997 ). However, in order to successfully carry out everyday tasks, it is also necessary to be able to perform concurrent motor and/or mentally challenging activities while walking, requiring input from the cognitive system. This ability to perform concurrent tasks or “dual task”, and the effect

Dancing is a complex sensorimotor activity involving physical and mental elements which have positive effects on cognitive functions and motor control. The present randomized controlled trial aims to analyze the effects of a dancing program on the performance on a motorcognitive dual task. Data of 35 older adults, who were assigned to a dancing group or a health-related exercise group, are presented in the study. In pretest and posttest, we assessed cognitive performance and variability of minimum foot clearance, stride time, and stride length while walking. Regarding the cognitive performance and the stride-to-stride variability of minimum foot clearance, interaction effects have been found, indicating that dancing lowers gait variability to a higher extent than conventional health-related exercise. The data show that dancing improves minimum foot clearance variability and cognitive performance in a dual-task situation. Multi-task exercises (like dancing) might be a powerful tool to improve motor-cognitive dual-task performance.

The purpose of this study was to investigate the effects of the addition of a dual task to multicomponent training on cognition of active older adults. Eighty physically active older adults were divided into an intervention group (IG) and a control group (CG). Both groups performed multicomponent training over 12 weeks. The IG simultaneously performed exercises and cognitive tasks. The Mini-Mental State Examination, the Montreal Cognitive Assessment, and the Clock Drawing Test were used for cognitive assessments. The Timed Up and Go Test associated with a cognitive task was used for dual-task assessment. Significant interactions were not observed between groups in terms of the cognitive variables or the dual-task performance. An interaction was observed only for Timed Up and Go Test performance, which was better in the CG than in the IG. Active older adults showed no improvement in cognition following the addition of the dual task to the multicomponent training.

the variability of MTC. Dual-task costs during walking (e.g., deterioration of gait variability in a dual-task situation compared with normal walking) are often used to determine gait automaticity ( Clark, 2015 ). Although the variability of stride length or stride time increases during dual-task

In PD, gait impairments become exacerbated under dual-task (DT) conditions, or the simultaneous performance of two attention-demanding tasks ( Kelly, Eusterbrock, & Shumway-Cook, 2012 ; Penko et al., 2018 ). Decreased gait performance under DT conditions in PD has been attributed to

the reason for the increased risk is not clear. The effects of concussion can last months after diagnosis, and many traditional tests do not detect persistent deficits. 3 The use of a dual-task assessment, which adds a cognitive load to a motor assessment, has the potential to be a more sensitive
