Challenging walking environments increase cognitive-motor interference in stroke survivors during dual-task walking. Task prioritization differs between environments, with physical context favoring motor tasks and augmented reality favoring cognitive tasks.
Area of Science:
- Neurorehabilitation
- Biomechanics
- Human-Computer Interaction
Background:
- Cognitive-motor interference and inappropriate task prioritization are linked to fall risk in stroke survivors.
- Dual-task walking assessments offer insights for evaluating and treating gait in this population.
Purpose of the Study:
- To investigate the impact of varied walking environments on cognitive-motor interference and task prioritization during dual-task walking in individuals post-stroke.
- To compare dual-task walking performance in plain, physically enriched, and projector-augmented environments.
Main Methods:
- A repeated-measures design was employed with 30 stroke survivors.
- Cognitive-motor interference and task prioritization were assessed during dual-task walking (walking plus serial-3 subtraction) in three environments: plain, stationary physical context, and projector-augmented context.
- Performance was compared across conditions.
Main Results:
- Challenging environments (physical context and projector-augmented) elicited greater cognitive-motor interference than the plain environment.
- Cognitive-motor interference did not significantly differ between the two challenging environments.
- Task prioritization varied: motor performance was prioritized in the physical context environment, while cognitive task performance was prioritized in the projector-augmented environment.
Conclusions:
- The walking environment significantly modulates cognitive-motor interference and task prioritization during dual-task walking in stroke survivors.
- Environmental complexity influences how individuals with stroke allocate resources between cognitive and motor tasks.
