Video game and motor-cognitive dual-task training could be suitable treatments to improve dual-task interference in older adults

The objective of study was to investigate the effects of video game training in comparison with traditional motorcognitive dual-task training on dual-task interference in older adults. Sixty older adults were allocated to the video game (intervention group) or the motor-cognitive dual-task training (control group). The outcome measures were dual-task cost (DTC) of linear metrics (Standard deviation (SD) of amplitude and velocity) and DTC of nonlinear metrics (approximate entropy, Lyapunov and correlation dimension) acquired from postural sway time series from both the mediolateral (ML) and anteroposterior (AP) directions. The results revealed in both groups, dual-task cost of SD of amplitude and velocity as well as Lyapunov were significantly decreased in post-training and follow-up compared with pre-training (p < 0.017), while there was no significant difference between the groups. Video game and motor-cognitive dual-task training could be recommended as suitable treatments to improve dual-task interference.

Automated summary

The study aimed to compare the effects of video game training and traditional motorcognitive dual-task training on dual-task interference in older adults. Both types of training showed significant reductions in dual-task cost in amplitude, velocity, and Lyapunov, indicating they are suitable treatments for improving dual-task interference.
