People post-stroke prioritize cognitive tasks, showing significant gait changes during dual-task walking. Speech tasks caused more gait interference than visuospatial or memory tasks.

Area of Science:

  • Neuroscience
  • Rehabilitation Science
  • Human Movement Studies

Background:

  • Gait and cognitive function are often impaired after stroke.
  • Understanding dual-task interference is crucial for improving daily functioning and fall prevention in stroke survivors.

Purpose of the Study:

  • To investigate the effects of combining walking with different cognitive tasks on gait parameters and cognitive performance in individuals post-stroke.
  • To compare the interference effects of visuospatial, working memory, and speech tasks on gait and cognition.

Main Methods:

  • Thirteen community-dwelling individuals post-stroke performed walking alone, seated cognitive tasks, and dual tasks (walking + cognitive).
  • Gait data (speed, stride time, length, cadence) were continuously recorded.

Dual-Task Stroop Paradigm for Detecting Cognitive Deficits in High-Functioning Stroke Patients

Published on: December 16, 2022

  • Cognitive performance was assessed via reaction time, accuracy (visuospatial, memory), and speech analysis.

    • Main Results:

    • Dual-tasking significantly affected gait speed, stride time, stride length, and cadence, but not stride time variability.
    • The speech task caused greater gait interference compared to visuospatial and memory tasks.
    • Cognitive interference was minimal, with only speech performance significantly impacted by concurrent walking.

    Conclusions:

    • Individuals post-stroke prioritize cognitive tasks over gait when performing dual tasks, leading to significant gait modifications.
    • Speech tasks pose a greater challenge to gait stability than visuospatial or memory tasks in this population.
    • Future research should explore dual-task training to mitigate gait deficits in post-stroke individuals.
