简介：
Overview
This protocol allows for selective manipulation of movement affordances and constraints to aid in balance recovery after postural perturbation. By controlling visual access and altering the response environment, the method emphasizes cognitive processes involved in decision making and response inhibition.
Key Study Components
Area of Science
- Neuroscience
- Motor control
- Balance recovery
Background
- Traditional balance assessments focus on reflexive actions.
- Automatic postural reactions may not be adaptable to changing environments.
- Modifying reactions can enhance balance recovery strategies.
- Visual control is crucial in assessing balance responses.
Purpose of Study
- To develop a protocol that alters movement affordances and constraints.
- To investigate cognitive processes in balance recovery.
- To assess the impact of visual manipulation on motor responses.
Methods Used
- Participants provide informed consent and undergo EMG data collection.
- Liquid crystal goggles control visual access during trials.
- Participants perform balance tasks with varying obstacle configurations.
- Response settings are randomized to assess adaptability in balance recovery.
Main Results
- Participants demonstrated varying abilities to suppress automatic stepping responses.
- Significant correlations were found between response inhibition and balance recovery.
- Transcranial magnetic stimulation revealed insights into motor system activation.
- Visual access influenced the effectiveness of balance recovery strategies.
Conclusions
- The protocol effectively highlights the role of cognitive processes in balance recovery.
- Findings suggest potential applications in clinical populations with cognitive decline.
- Further research could explore the implications for rehabilitation strategies.
