The interactive effect of cognitive and physical dual task interventions on obstacle negotiation while walking in healthy young, and older, adults.

Context: Dual task performance affects obstacle crossing ability in older adults. Previous studies suggest that cognitive dual tasking can lead to changes in obstacle crossing performance in older adults, but there is a lack of evidence to support changes in obstacle crossing performance due to the influence of motor dual tasking.

Aims: To investigate the interaction of cognitive and motor tasks, on obstacle crossing performance, in healthy young and older adults.
