Abstract

The aims of this study were to examine the effect of cognitive dual-tasking in spatiotemporal aspects of gait in people with neurological conditions and healthy people. Ten volunteers (M=63.88 years, SD=10.39) with hemiparetic stroke and acquired brain injury and ten age-matched (M=72.66 years, SD=8.10) healthy people were selected non-randomly. The actual task manipulation consisted of 2 constraints: stride change through external stimuli and dual-task through a cognitive task. Participants walked on the treadmill for 2 minutes and data were collected for different temporal and spatial gait parameters. In the dual-task condition, participants were required to count backwards and subtract 3 numbers from 1000. The results of paired t test showed that in patients group dual-task condition significantly increased the duration of step and stride and variability of stride time, whereas there was not any significant difference between two conditions in healthy group. In conclusion, adding a cognitive secondary task whilst walking can constrain the sensory-motor integration in neurological patients and it could be a good modality to enhance the selective attention in people who suffer from dysexecutive function.
