This study shows that adapting to visual feedback changes postural symmetry during quiet standing. These postural control adjustments persist even after the visual feedback is removed.
Area of Science:
- Neuroscience
- Biomechanics
- Human Motor Control
Background:
- Postural symmetry is crucial for stable standing.
- Sensorimotor adaptation can modify motor control strategies.
Purpose of the Study:
- To investigate how sensorimotor adaptation affects postural symmetry during quiet standing.
- To determine if adaptive changes in postural control persist after visual feedback removal.
Main Methods:
- Participants performed a visually guided weight-shifting task with biased center of pressure (COP) feedback.
- Postural sway and COP measures during quiet standing were assessed before and after adaptation.
Main Results:
- Sensorimotor adaptation induced a reliable, albeit small, compensatory shift in stance.
- This induced change in postural symmetry and control persisted after normal visual feedback was restored.
Conclusions:
- Visual-feedback-based sensorimotor adaptation can lead to lasting changes in postural control.
- The nervous system retains adaptive postural adjustments, impacting balance during quiet standing.
