Two motor-cognitive interventions were implemented to evaluate their efficacy in cognitive improvement in Mexican older adults 65 years and more. The intervention group received a dance video games plus a cognitive task (dual-task); the comparison group received only the dance video game, in sessions of 45 minutes, 3 times a week, for 12 weeks. The Barthel Index and Lawton and Brody Index, the Center for Epidemiologic Studies Depression Scale-Revised were applied the Digit Span Test, the Stroop Test, and Color Trail Making. Gait parameters were assessed by GAITRite? electronic walkway (CIR Systems). The design was quasi-experimental. Sites were randomly assigned to intervention groups. The intervention group started with 32 participants and finished with 15; the comparison group started with 20 participants and finished with 18. Participants in the intervention group had to mimic the dance movement of a video game and, after the second week to name progressively three objects without stopping dancing. A multivariate repeated measures model (MANO-VA) was fit with four variables. A time-by-group interaction was observed in the Stroop test, and Digits Span Backwards was in favor of the dual task group. The Stroop test, Digit Span Backwards, gait speed, and step length showed effect time. Both groups improved in gait speed and step length by the end of the intervention. Results show it is feasible for Mexican older adults with little schooling to perform dual tasks and improve cognitive tasks and gait speed. Limitations were high attrition due to unforeseen situations and small sample size.
