When we perform two tasks simultaneously, we often cannot perform each task completely, and performance in either one or both tasks is inadequate. This decrement is defined as dual-task interference. Dual-task interference causes various accidents, such as falls. Thus, dual-task interference is one problem that physiotherapists need to solve. To repeat dual tasks (i.e., dual-task training) was a famous method to reduce dual-task interference. However, the effect of dual-task training might be limited to repeated dual tasks. That is, it has become clear that the transfer effect of dual-task training might be poor. In this review, we outlined the methods and limitations of dual-task training. Subsequently, as new methods to reduce dual-task interference, we presented potentials for transcranial direct current stimulation and cognitive tasks. Through this review, we hope to contribute to the reduction of dual-task interference in clinical fields.
