Summary
Stroke survivors show partial transfer of treadmill walking adaptations to overground walking. This suggests shared neural circuits, offering potential benefits for post-stroke rehabilitation by improving gait symmetry.
Area of Science:
- Neuroscience
- Rehabilitation Science
- Biomechanics
Background:
- Locomotor adaptation is possible after stroke.
- Understanding treadmill adaptation transfer to overground walking is crucial for rehabilitation.
Purpose of the Study:
- To investigate if split-belt treadmill adaptation aftereffects transfer to overground walking in healthy individuals and stroke survivors.
- To assess the robustness of this transfer between different walking environments.
Main Methods:
- 11 poststroke and 11 healthy subjects walked overground before and after split-belt treadmill adaptation.
- Measured adaptation and aftereffects in step length and double support time.
Main Results:
- Both groups showed partial transfer of treadmill aftereffects to overground walking.
- Transfer was more pronounced in stroke survivors.
- Stroke survivors with baseline asymmetry improved in step length and double limb support symmetry.
Conclusions:
- Partial transfer indicates shared neural control for locomotion across different environments.
- Stroke survivors' greater adaptation transfer may stem from challenges in adjusting to environmental changes.
- Persistent symmetry improvements offer a potential rehabilitation advantage for stroke survivors.
